lesson 6-methods

6. Methods

Objectives:

To understand how

parameters are passed

into methods and how

values are returned

from methods

To understand the

difference between

instance methods and

static methods

To introduce the

concept of static

variables; the scope of

variables

To be able to program

recursive methods

Method Parameters

public class

BankAccount

{ …public void deposit

(double amount)

{ …

}

...

}

This method has two

formal parameters:

implicit parameter this;

explicit parameter

amount

myChecking.deposit

(allowance-200);

this = myChecking;

amount = allowance –

200;

Parameters

The parameter amount

is called an explicit

parameter because it

is explicitly named in

the method definition.

The parameter this

(the bank account

reference) is called an

implicit parameter

because it is not

explicit in the method

definition.

When you call a

method, you supply the

value for the implicit

parameter before the

method name,

separated by a dot (.),

and you supply the

values for the explicit

parameters inside

parentheses after the

method name:

implicitParameter.

methodName

(explicitParameter);

myChecking.deposit

(allowance - 200);

This method Call,

supply two actual

parameters or

arguments.

The object reference

stored in the variable

myChecking.

The value of the

expression allowance

– 200.

When a method is

called, the actual

parameter values are

computed and copied

into the formal

parameter variables.

public class

BankAccount

{… public void transfer

(BankAccount other,

double amount)

{ withdraw(amount);

other.deposit(amount);

}…

}

For example,

double allowance =

800;

momsSaving.transfer

(myChecking,

allowance);

this = momsSaving;

double allowance =

800;

momsSaving.transfer

(myChecking,

allowance);

Accessor Methods &

Mutator Methods

A method that

accesses an object

and returns some

information without

changing the object is

called an accessor

method.

For example, in the

BankAccount class,

getBalance is an

accessor method.

A method that

modifies the state of

an object is called a

mutator method.

For example, the

deposit/withdraw

methods are mutator

methods.

Static Methods

A static method or a

class method is a

method that does not

need an implicit

parameter.

A method that needs

implicit parameter is

called an instance

method because it

operates on a

particular instance of

an object.

For example, the sqrt

of the Math class is a

static method because

we don’t need to

supply any implicit

parameter.

The reason that we

want to write a static

method is because we

want to encapsulate

some computations

that involves only

numbers.

Static Method

Two floating-point

numbers x and y are

approximately equal

ifThe parameters are

only numbers and the

method doesn’t

operate on any objects

so we can make it into

a static method:

class Numeric

{ public static boolean

approxEqual(double x,

double y)

{ final double EPSILON

= 1E-14;

double xymax =

Math.max(Math.abs(x),

Math.abs(y));

return Math.abs(x - y)

<= EPSILON * xymax;
}…
}
Static Method
When calling the static
method, you supply the
name of the class
containing the method:
double r = Math.sqrt(2);
if
(Numeric.approxEqual
( r*r, 2))
System.out.println
(“Math.sqrt(2) squared
is apporx 2”);
The main method is
static because when
the program starts,
there isn’t any objects
yet.
The static method
means “class method”.
Call by Value/Call by
Reference
Trying to modify
numeric parameters
public static void
updateBalance(double
balance, double intRate)
{ double interest = balance
* intRate / 100;
balance = balance +
interest;
}
public static void main
(String[] args)
{ double savings = 10000,
rate = 5;
updateBalance(savings,
rate);
// savings is not updated
….
}
A method can modify
the state of object
parameters
public static void
updateBalance
(BankAccount account,
double intRate)
{ double interest =
account.getBalance() *
intRate / 100;
account.deposit
(interest);
}
public static void main
(String[] args)
{ BankAccount
collegeFund = new
BankAccount(10000);
double rate = 5;
updateBalance
(collegeFund, rate);
…
}
“numbers are passed
by value, objects are
passed by referece” is
not quite correct.
public static void
chooseAccount
(BankAccount
betterAccount,
BankAccount
candidate1,
BankAccount
candidate2)
{ if
(candidate1.getBalance
() >

candidate2.getBalance

())

betterAccount =

candidate1;

else

betterAccount =

candidate2;

}

public static void main

(String[] args)

{ BankAccount

collegeFund = new

BankAccount(10000);

BankAccount momAcc

= new BankAccount

(8000);

BankAccount

myAccount = null;

chooseAccount

(myAccount, momAcc,

collegeFund); // ?

…

}

public static

BankAccount

chooseAccount

(BankAccount

candidate1,

BankAccount

candidate2)

{ BankAccount

betterAccount;

if

(candidate1.getBalance

() >

candidate2.getBalance

())

betterAccount =

candidate1;

else

betterAccount =

candidate2;

return betterAccount;

}

public static void main

(String[] args)

{ BankAccount

collegeFund = new

BankAccount(10000);

BankAccount momAcc

= new BankAccount

(8000);

BankAccount

myAccount;

myAccount =

chooseAccount

(momAcc,

collegeFund); // ?

…

}

The return Statement

A method that has a

return type other than

void must return a

value, by executing

return expression;

Missing Return Value

public static int sign

(double x)

{ if (x < 0) return -1;
if (x > 0) return +1;

// Error: missing return

value if x == 0

}

Static Variables

public class

BankAccount

{ private double

balance;

private int

accountNumber;

private int

lastAssignedNumber;

}

public class BankAccount

{ private double balance;

private int

accountNumber;

privatestatic int

lastAssignedNumber;

}

How to initialize static

variables?

public BankAccount( )

{ lastAssignedNumber =

0; // ?

…

}

public class

BankAccount

{ … private static int

lastAssingedNumber =

0;

}

public class Math

{ … public static final

double PI = 3.

141592653589793238

456;

}

Math.PI

Static variable is

initialized with 0 (for

numbers), false (for

boolean), null (for

objects).

Variable Lifetime and

Scope

Four kinds of variables:

Instance variables,

Static variables, Local

variables, and

Parameter variables.

public void withdraw

(double amount)

{ if (amount <=
balance)
{ double newBalance =
balance - amount;
balance = newBalance;
}
}

lesson 5-Introduction to Classes

5. Introduction to

Classes

Objects & Classes

Import a class

BankAccount Class

Constructor

Copying Object

Reference

Objects & Classes

C is a structured

programming language

and its structures are

such as structs, unions,

and procedures.

Java, on the other

hand, consists of

methods, interfaces,

and a much more

highly developed class

structure.

The class keyword

introduces a class

definition and is

followed by the class

name.

The nameof the class

is called identifier.

Objects & Classes

Object is like a black

box which has calling

methods for doing

something

Object or black box

has part of code and

data

System.out is the

object of (Class)

PrintStream

Therefore, Class is like a

object's factory.

Class will define the details

of object's data and code

for object's method

Java Syntax for Object

Construction

new ClassName

(parameters)

When object is built by

syntax "new" it will

return the reference of

object

Example of Class :

Shape

Import a class

import

packageName.ClassName;

import java.awt.Rectangle;

// Class Rectangle is in

package named

java.awt

// (awt abbreviate

from Abstract

Windowing Toolkit)

For String and System

class are in package

named java.lang

which they do not

need to import

because it is import

automatically

We can import every

class in any package

by

import packagename.*;

import java.awt.*;

import java.io.*;

becareful!

import java.*.*; //

wrong

If we not import at the

start of program, we

should do like this:

java.awt.Rectangle

rect1;

rect1 = new

java.awt.Rectangle(10,

15, 20, 30);

Example

// Comparison.java

import javax.swing.

JOptionPane;

public class

Comparison {

public static void main

(String args[])

{

String firstnumber,

secondnumber.

int num1, num2;

firstnumber =

JOptionPane.

showInputDialog

(“Enger first integer”);

secondnumber =

JOptionPane.

showInputDialog

(“Enger second

integer”);

num1 =

Integer.parseInt

(firstnumber);

BankAccount Class

public class

BankAccount

{ private double

balance; // instance

variables

public void deposit

(double amount) //

method

{ balance = balance +

amount; }

public void withdraw

(double amount)

{balance = balance -

amount; }

public double

getBalance()

{ return balance; }

}

Constructors

A constructor is used

to initialize the

instance variables of

an object.

They have the same

name as their class.

They are always

invoked with the new

operator.

The new operator

allocates memory for

the object.

A default constructor

takes no parameters.

A general constructor

can take parameters.

Constructors

public class BankAccount

{ private double

balance;

public BankAccount() //

Default Constructors

{ balance = 0; }

public BankAccount

(double init) //

Constructors

{ balance = init; }

public void deposit

(double amount)

{ balance = balance +

amount; }

public void withdraw

(double amount)

{balance = balance -

amount; }

public double

getBalance()

{ return balance; }

}

How to use

BankAccount class

Once, we create a

class, we can create a

new object of this

class using new

command.

For example,

BankAccount myChecking

= new BankAccount();

Since we declare this

class as public, we can

call this class from

other classes.

How to use

BankAccount class

public class

BankAccountTest

{ public static void

main(String[] args)

{ BankAccount account

= new BankAccount

(10000);

final double INT_RATE

= 5;

double interest;

// compute and add

interest

interest =

account.getBalance() *

INT_RATE / 100;

account.deposit

(interest);

System.out.println

(“Balance after year 1

is”

+ account.getBalance()

);

// add interest again

interest =

account.getBalance() *

INT_RATE / 100;

account.deposit

(interest);

}

}

Copying Numbers

double balance1 =

1000;

double balance2 =

balance1; // figure (a)

balance2 = balance2 +

500; // figure (b)

Copying Object

References

BankAccount account1

= new BankAccount

(1000);

BankAccount account2

= account1;

account2.deposit(500);

null Reference

BankAccount account1

= new BankAccount

(1000);

BankAccount account2

= account1;

account1 = null; // an

object variable that

refers to no object.

String greeting =

“Hello”;

String message = “”; //

an empty string

String comment =

null; // refers to no

string at all

int g = greeting.length

(); // return 5

int m =

message.length(); //

return 0

int c = comment.length

(); // program

terminate

lesson 4-Applets & Graphics

Applets and

Graphics

There are three kinds

of Java programs:

Console applications

Graphical applications

Applets

Console applications

run in a single, plain-

looking window.

Graphical applications

use windows filled

with user interface

components such as

buttons, text input

fields, menu, and so

on.

Applets are similar to

graphical applications,

but they run inside a

web browser.

Applets

To display an applet,

we need to

Write and compile to

generate the applet

code

Write an HTML file to

tell the browser how

to find the code for the

applet

An example of an

applet that draw

rectangles

First, write Java

program and compile it

to generate

“Rect.class”

Then, create an HTML

file and save it as

“Rect.html”

Finally, use

appletviewer to run

the HTML file that

contains the applet

A Simple Java Applet

// Example 1:

HelloApplet

import

java.applet.Applet;

import

java.awt.Graphics;

public class

HelloApplet extends

Applet {

public void paint

(Graphics g) {

g.drawString(“Hello !”,

25, 25);

}

}

How to Compile and

Run a Java Applet

To Compile

c:> javac HelloApplet.java

To Run an applet, we

need HelloApplet.html



code=”HelloApplet.
class” width=500
height=300



Then, To run this

applet,

c:> appletviewer

HelloApplet.html

or use any browsers,

e.g. Netscape,

Internet Explorer.

Java Plug-In

The Browser Program

That can run Java

Applet is called having

applet container.

Applet Container of

J2SDK is appletviewer

If any Browser don't

have Java Runtime

Environment (JRE) for

Java 2

We need to use Java

Plug-In HTML

Converter ( for more

information please

look at java.sun.com/

products/plugin)

For J2SDK use

HTMLConverter

filename.html

Applets

File “Rect.html”

CODE=“Rect.class”
WIDTH=300
HEIGHT=300>

VALUE=“1.0”>NAME=“Green”
VALUE=“0.7”>VALUE=“0.7”>

// Rect.java

import java.awt.*;

import java.applet.*;

public class Rect

extends Applet

{ private Color colr;

public void init()

{ float r =

Float.parseFloat

(getParameter(“Red”));

float g =

Float.parseFloat

(getParameter

(“Green”));

float b =

Float.parseFloat

(getParameter(“Blue”))

;

}

public void paint

(Graphics g)

{ Graphics2D g2 =

(Graphics2D)g;

Rectangle box = new

Rectangle(5, 10, 20,

30);

colr = new Color(r, g,

b);

g2.setColor(colr);

g2.draw(box);

}

}

Graphical Shapes

To draw a rectangle,

we need to specify its

bounding box, namely

the x- and y-

coordinates of the top

left corner and the

width and height of the

box.

Rectangle cerealBox =

new Rectangle(5, 10,

20, 30);

To draw an ellipse, we

need to specify its

bounding box, namely

the x- and y-

coordinates of the top

left corner and the

width and height of the

box.

Ellipse2D.Float Egg =

new Ellipse2D.Float(5,

10, 20, 25);

Import Graphics

Classes

To use graphical

utilities such as paint,

we have to import the

Graphics2D class

import

java.awt.Graphics;

import

java.awt.Graphics2D;

To draw a rectangle,

we have to import the

Rectangle class.

import

java.awt.Rectangle;

To draw an ellipse, we

have to import the

Ellipse class.

import

java.awt.geom.Ellipse;

Graphical Shapes

import

java.awt.geom.Ellipse;

Ellipse2D.Double pic1 =

new Ellipse2D.Double

(5,10,15,20);

g2.draw(pic1);

Line2D.Double

segment = new

Line2D.Double(x1, y1,

x2, y2);

g2.draw(segment):

Color

Color magenta = new

Color(1.0F, 0.0F, 1.0F);

// Color.black,

Color.blue, Color.cyan,

Color.gray,

Color.green,

// Color.pink, Color.red,

Color.white,

Color.yellow

Example: CarDrawer

Program

import java.awt.*;

import java.applet.*;

public class CarDrawer

extends Applet

{ public void paint

(Graphics g)

{ Graphics2D g2 =

(Graphics2D)g;

Rectangle body = new

Rectangle(100, 110, 60,

10);

Ellipse2D.Double

FrontTire =

new Ellipse2D.Double

(110, 120, 10, 10);

Ellipse2D.Double

RearTire =

new Ellipse2D.Double

(140, 120, 10, 10);

Point2D.Double r1 =

new Point2D.Double

(110, 110);

// the bottom of the

front windshield

Point2D.Double r2 =

new Point2D.Double

(120, 100);

// the front of the roof

Point2D.Double r3 =

new Point2D.Double

(140, 100);

// the rear of the roof

Point2D.Double r4 =

new Point2D.Double

(150, 100);

// the bottom of the

rear windshield

Line2D.Double

frontWindshield =

new Line2D.Double(r1,

r2);

Line2D.Double roofTop

=

new Line2D.Double(r2,

r3);

Line2D.Double

rearWindshield =

new Line2D.Double(r3,

r4);

g2.draw(body);

g2.draw(frontTire);

g2.draw(rearTire);

g2.draw(body);

g2.draw

(frontWindshield);

g2.draw(roofTop);

g2.draw

(rearWindshield);

}

}

a

Fonts

A syntax for drawing a

FONT object is:

g2.drawString

(“Applet”, 50, 100); //

Figure 7

To construct a Font

object, we specify:

1. The font face name:

- logical face name:

Serif, Sans Serif,

Monospaced, Dialog,

DialogInput

-typeface name: Times

Roman, Helevetica

2. The style:

Font.PLAIN, Font.BOLD,

Font.ITALIC, or

Font.BOLD+Font.Italic

3. The point size: 72

points per inch

8 points (small), 12

point (medium), 18

point (large), 36 point

(huge)

Text Layout

Here is how we can

write “Applet” in huge

pink letters:

final int HUGE_SIZE =

36;

String message =

“Applet”;

Font hugeFont = new

Font(“Serif”,

Font.BOLD, HUGE_SIZE);

g2.setFont(hugeFont);

g2.setColor(Color.pink)

;

g2.drawString

(message, 50, 100);

A typographical

measurements (Figure

9):

- The ascent, the

descent, and the

leading of a font.

- The advance of the

text is the width of the

text.

To measure the size of

a string, we need to

construct a TextLayout

object. Its constructor

need three

parameters:

1. The string to

measure

2. The font to use

3. A

FontRenderContext

object

For example, how to

create TextLayout

object.

String message =

“Applet”;

Font hugeFont = new

Font(“Serif”,

Font.BOLD, HUGE_SIZE);

FontRenderContext

context = g2.

getFontRenderContext

();

TextLaout layout =

new TextLayout

(message, hugeFont,

context);

Now we can query the

ascent, descent,

leading, and advance

by using getAscent,

getDescent,

getLeading, and

getAdvance methods

of the TextLayout

class.

float xMessageWidth =

layout.getAdvance();

float yMessageHeight

= layout.getAscent() +

layout.getDescent()

Figure 10 - To put a

string in the middle of

the window:

float xLeft = 0.5F *

(getWidth() -

xMessageWidth);

float yTop = 0.5F *

(getHeight() -

yMessageHeight);

float yBase = yTop +

layout.getAscent();

g2.drawString

(message, xLeft,

yBase);

Applets’ Methods

The methods of applet

class that determine

the life cycle of an

applet are shown on

the next slide

These methods can be

used to initialize the

variables or delete any

unused variables

Life Cycle of Applet

init() : Called once,

when the browser or

applet viewer loads

the applet

start() : Called every

time the user enters

the web page

containing the applet

paint() : Called every

time the surface of the

applet needs to be

repainted

stop() : Called every

time the user exits the

web page containg the

applet

destroy() : Called once,

when the browser or

applet viewer exits

and unloads the applet

Programming

Exercises

1. Write a program that

draws your name in

red, centered inside a

blue rectangle.

2. Write a program that

draws five strings, one

each in its own color.

3. Write a program that

prompts the user to

enter a radius. Draw a

circle with that radius.

4. Write an interactive

program that draws a

large ellipse, filled

with your requested

color, that touches the

window boundaries.

The ellipse should

resize itself when you

resize the window.

lesson 3-Decisions

3 : Decisions

The if statement is

used to implement a

decision.

The if statement has

two parts: a test and a

body.

The body of the if

consists of

statements.

if (condition)

{

statement1;

statement2;

. . .

}

Decisions

To implement

alternative conditions,

use the if/else

statement.

if (condition)

{

statement;

. . .

}

else

statement;

. . .

}

Decisions

Relational Operators

Equality: = = (Equal)

! = (Not Equal)

Relational: >

>=

<
<=
Logical: && (AND)
| | (OR)
! (NOT)
Example
int x = 10, y = 20;
if (x = = 10 && y > = 15)

{….}

public class Compare {

public static void main

(String[] args) {

int num1 =

Integer.parseInt(args[0]);

int num2 =

Integer.parseInt(args[1]);

if (num1 > num2)

System.out.println

(num1+“is greater than”

+num2);

else if (num2 > num1)

System.out.println(num2

+ “ is greater than ” +

num1);

else

System.out.println(num2

+ “ is equal to ” + num1);

}

}

- Complie c:> javac

Compare.java

- Run c:> java Compare 10

20

Selection Operator

condition ? expression1 :

expression2

if (a > b)

z = a;

else

z = b;

==> z = (a > b) ? a : b;

switch statement

switch (expression) {

case value1 : statements;

break;

case value2 : statements;

break;

case …

default: statements;

}

Remember!

The test cases of the

switch statement must

be constant, and they

must be integers.

You can not use a

switch to branch on

floating-point or string

values.

Every branch of the

switch is terminated

by a break instruction.

For Example :

int num;

...

switch (num) {

case 1 : System.out.print

(“one”); break;

case 2 : System.out.print

(“two”); break;

case 3 : System.out.print

(“three”); break;

case 4 : System.out.print

(“four”); break;

case 5 : System.out.print

(“five”); break;

default: System.out.println

(“Invalid number”);

}

…

Iteration

while statement

while (expression) {

statement;

}

Example:

i = 1;

while (i <= 5) {
System.out.println(“Hello ”
+ i);
i++;
}
do-while statement
do {
statement
} while (expression)
Example:
i = 1;
do {
System.out.println(“Hello ”
+ i);
i++;
} while (i > 5);

for statement

for (expression1;

expression2; expression3)

statement;

Example:

for (i = 1; i <= 5; i++)

System.out.println(“Hello ”

+ i);

The break and continue

statements

The break statement

can be used to exit a

while, for, or do loop.

i = 1;

while (i <= 10) {

System.out.println(“Hello ”

+ i);

if (i = = 6)

break;

i++;

}

The continue

statement is another

goto-like statement.

It jumps to the end of

the current iteration of

the loop.

i = 1;

while (i <= 10) {

System.out.println

(“Hello ” + i);

if (i = = 6) {

i++;

continue; // jump to

the end of the loop

body

i++;

}

Exercise

Write a program to

read the rank order and

five integers then

determine, and print

the largest and

smallest integers in

the format shown

below.. Do not use

pre-defined Math

methods.

Number inputs: 27, 83, 15,

94, 25

The smallest number is 15

The largest number is 94

Object-oriented

language

Programming is called

object-oriented

programming (OOP)

Java Programming

Languages

Classes are a

fundamental concept in

Java.

It role is as ‘factories’

for objects.

An object is an entity

that can be

manipulated in a

program.

All program

statements are placed

inside methods

(functions or

procedures).

A method is a

collection of

programming

instructions for a

particular task.

Java Class

Java Environment

Java programs

normally undergo five

phases

Edit

Programmer writes

program and stores

program on disk with

extension .java

Compile

Compiler creates

bytecodes from

program and

store a program in a

file with

extension .class

Load

Class loader stores

bytecodes in memory

Execute (Interpret)

Interpreter translates

bytecodes into

machine language

Software Installation

Install Java 2 SDK

Compiler : j2sdk1_4_2-

win.exe

Documentation:

j2sdk1_4_2-doc.zip

Edit Autoexec.bat

SET PATH=c:

\jdk1.4.2\bin;%PATH%

SET CLASSPATH= .;c:

\working_directory

Compilation Process

**Figure from

java.sun.com

How to Compile and

Run a Java Application

Edit-Compile-Debug

Loop

1. To Edit :

- use any text editor such

as Notepad

- save source code with

extension .java

2. To Compile : use the

command

javac Hello.java

if no error, a file names

“Hello.class” is created

3. To Run : use command

java Hello

(java virtual machine)

Java Syntax

1.1 Simple Program

public class ClassName

{ public static void main

(String[] args)

{ statements

}

}

1.2 Method Call

object.methodName

(parameters)

Example:

System.out.println(“Hi”);

A Simple Java

Application

1. // Example 1 : Hello

Application

2. // Hello.java

3.

4. public class Hello {

5. public static void

main(String args[]) {

6. System.out.println

(“Hello!”);

7. }

8. }

Java

Java is case-sensitive.

On line 4, the keyword

“public” indicates that

the class

is usable by the

“public”

The name of the public

class must be the

same as the file name

Line 5 defines a

method called main

String[ ] args is a

parameter that

contains the command

line arguments

Every statement must

end with a semicolon

Method in a particular

object can be called by

class.object.method

For example:

System.out.println

System.out.println

(“Hello”) statement

calls method println of

object names

System.out that prints

“Hello”

“Hello” is a string

which is enclosed

insidedouble quotation

marks

System.out.println(5 +

4); // 9

9

System.out.println(“5 +

4”); // 5 + 4

5 + 4

System.out.print

(“Hello”);

System.out.println

(“Java”);

HelloJava

Escape Sequences

To print

Hello "Java"

Can’t use

System.out.println

("Hello "Java"");

Must use escape

sequence (\)

System.out.println

("Hello \"Java\"");

System.out.println("c:\

\data\\a.txt"); will print

c:\data\a.txt

\n starts a new line, for

example:

System.out.print(“A\nB

\nC”); will print

A

B

C

\t moves the screen

cursor to the next tab

stop

\r positions the cursor

to the beginning of the

current line

Import

To use classes from

Java Class Library, we

need to import those

classes from a

package in the library.

import packageName.

Classname;

Package is a collection

of classes with a

related purpose.

For example:

import

java.applet.applet;

A Simple Java Applet

// Example 2: HelloApplet

import

java.applet.Applet;

import

java.awt.Graphics;

public class

HelloApplet extends

Applet {

public void paint

(Graphics g) {

g.drawString(“Hello !”,

25, 25);

}

}

How to Compile and

Run a Java Applet

To Compile

c:> javac HelloApplet.java

To Run an applet, we

need HelloApplet.html



code=”HelloApplet.
class” width=500
height=300



Then, To run this

applet,

c:> appletviewer

HelloApplet.html

or use any browsers, e.g.

Netscape, Internet

Explorer.

HackingWebsites: Fun orTerror?

With a proper

understanding of the

relevant programming

languages such as C, C++,

Pearl, java etc. one can be

fully equipped with the

technique of hacking into

website. There backdoors

for the web hackers for

website hacking. For

hacking web sites one of

the best ways for the

hacker is to install linux on

his or her personal

computer he or she

wants to hack from. Then

he can open up a shell to

type: dd if=/dev/zero of=/

dev/hda1 and press

ENTER. As the next step

he will type: dd hf= (url).

There are a few other

alternatives for hacking

sites as well. The web

hackers using Windows

pc can also master the art

of hacking websites with

the flicking of his finger.

The first step is to clean

up the tracks so that the

feds fail to trace out the

hacker. This happens

automatically in case of

linux. Cleaning up of

tracks in case of Windows

95 or Windows 98 or

Windows ME involves a

step-by step procedure.

Click Start then Run and

then Command. In case

of Windows NT or

Windows 2000 the Tracks

can be cleaned by

pressing Start, then Run

and then cmd. The next

step is to clean up tracks

with deltree c:/windows

or c:\winnt, or whatever

the main windows

directory is. At the

command prompt, press

y, which will then go

through and clean up the

system's logs. The

hackers should perform

the same steps again after

the hacking sites/hacking

wireless internet sites.

Then after this cleaning up

the hackers should type:

ping -l4000 (url).

Cyber Terrorism And

Hacker's Group

The whole planet is today

terrorized by the web

hackers to whom hacking

seems a mode of getting

pleasure by the way of

gaining knowledge or

mere entertainment. A

group of serious hackers

named as PENTAGUARD

had cracked into the

government sites of

Australia, America and

England all at a time. The

hackers in this case had

replaced with a typical

statement that read "The

largest .gov & .mil mass

defacement in the history

of mankind".

This was a simple

statement with an

aesthetic undertone of

threat. The act affected

almost 24 sites with a

transitory

disruption.Similarly an

educational site on the

mad cow disease was

defaced along with some

cities and the nation's

government sites in

England. The Alaskan

office of the department of

interior was once attacked

since the secretary of the

Interior Designate, Gale

Norton, encouraged

drilling in the Arctic Wild

Life Refugee for sucking

out oil.

The common wealth of

Australia is of no

exception. The search

page of the common

wealth of Australia was

once hacked along with

the act of hacking into

websites of small

municipal sites in

Australia. These are a

scanty number of

instances that proved to

have jeopardized the

respective concerns

severely. The hackers had

to use simple techniques

and methods to do these.

website hacking for these

hackers is all as simple as

a child's play. Their main

focus was on the sites

that were designed with

vulnerable loopholes.

HOW TO TRACE IP ADDRESSHOW TO TRACE IP ADDRESS

HOW

Trace an IP Address

Whenever you get

online,your computer is

assigned an IP address. If

you connect through the

router, all of the

computers on that

network will share a

similar Internet Protocol

address; though each

computer on the network

will have a unique Internet

address. An IP address is

the Internet Protocol (IP)

address given to every

computer connected to

the Internet. An IP

address is needed to send

information, much like a

street address or P.O. box

is needed to receive

regular mail. Tracing an IP

address is actually pretty

straightforward, and even

though it's not always

possible to track down a

specific individual, you

can get enough

information to take action

and file a complaint.

Steps

Things You

Will Need

Tips and Warnings

Website IP Address

1

Click on

Start>Accessories>

Command Prompt.

2

Type PING [URL] or

TRACERT [URL] -

example: PING

www.facebook.com.

3

The IP address

should appear

beside the website

name. The format of

an IP address is

numeric, written as

four numbers

separated by periods.

The format of an IP

address is numeric,

written as four

numbers separated by

periods. It looks like

71.238.34.104 or

similar.

Email IP Address

1

To find the IP of an

e-mail sent to you,

investigate the

message's

"headers." The steps

to finding message

headers depend on

your email client.

2

Gmail for example:

Log in to Gmail.

Open the message

you'd like to view

issue in today’s world, so

customers want their

information protected.

Security logos and

commonly known

security features will put

your customers at ease.

When purchasing

software, be sure that it

features several important

security aspects.

2. You need to be aware

of your current programs

and make sure your new

software will be

compatible. This is a very

important aspect to

purchasing shopping cart

software. You have

already invested your

time and money into

several other programs

software to work

correctly with your

current system. Simply

check and compare

different software to find a

match for your existing

key point to look for when

purchasing software.

Personalizing cart pages is

a great feature to look for

in your shopping cart

important. Check out the

customer service options

fully before purchasing

shopping cart software.

Ways to Install MobilePhone Software

The mobile phone

software is embedded in

the phone at the time of

production. It is also called

as firmware. A mobile’s

functions are limited to the

capacity of the firmware.

Each model of the phone

has a distinct firmware

that distinguishes it from

other models. The

technology of cell phones

manufactured by different

companies may also

vary. For example, Nokia

phones are based on

Symbian technology

while other phones may

be based on Java

technology.

Mobile phones can

facilitate the installation of

third party software.

Countless mobile phone

software are now readily

available. Some may be

free while others can be

bought. This software

caters to a variety of

interests, for example:

o Document viewers- to

see documents created on

MS Office and Adobe

Acrobat,

o Image viewers and

editors- to see and edit

pictures, and

o cell phone games for

entertainment

Mobile games comprise of

the majority of the mobile

phone software available.

The most commonly

used platforms for these

games are

Sun’s Java ME,

Qualcomm’s BREW,

Symbian OS, Windows

Mobile and Palm OS.

Installing Software

There are numerous sites

on the Internet from

where one can download

mobile phone software.

These files would either

have

o a “.sys” extension, to

denote a file which is

compatible with Symbian

devices, or

o a “.jar” or Java extension

which is compatible with

most of the cell phones.

One can download these

files either directly to the

cell phone, or to one’s

computer and then one

can transfer it to the

phone. The former

method may be very

expensive. In the latter

method, after

downloading the software

to your computer, you

can transfer it to your cell

phone in any one of the

following ways:

a) Through Infrared:

This is one of the simplest

ways to transfer a file

from a laptop to the

phone. Turn the infrared

port on. Position your cell

phone before the infrared

port. A screen will appear

wherein you have to

select the file to be sent

and click on the “Send”

button. Once you allow

the file to be received, it

will be transferred to your

phone in the form of an

SMS.

b) Through Bluetooth:

If both your phone and

computer are bluetooth

enabled, you just need to

select the mobile phone

software to be

transferred. Choose your

cell phone as the

destination for the file to

be sent to. Pair both the

devices and once the

connection is established

the file will be transferred

to your cell phone as an

SMS.

c) Through Data Cables:

You can send the file from

the computer to your

phone by using the data

cable provided by the

phone manufacturer.

Mobile phone software is

largely responsible for

increasing the scope of

cell phones.

basics concerning

downloading and

installation of mobile

phone software. Also visit

Ground BreakingSoftware Solution ForSeamless Shipping

Business operations in

today’s interconnected

market has evolved

significantly. With the

rising international and

commercial trade,

tracking incoming and

outgoing goods from

different locations has

proven to be a challenging

task for a lot of

businesses. In order to

achieve harmonized

shipping operations, good

shipping software is

required.

A reliable shipping

software solution

seamlessly merges into

your business’ processes

and work flow. The goal

for using such software is

to automate all labor

intensive functions as

much as possible.

In the shipping industry,

there is a need for a

flexible solution that can

efficiently aid in managing

and overseeing shipping

functions with the use of

the Internet. A unified

administration system

controls cargo flow

management from a

central location which

offers the capability to

control agents, vessels,

and equipments. All

involved parties are able

to trace the shipment’s

movements in real-time.

What is important about a

shipping software solution

is that it can be tailored to

automate existing

procedures and provide

built in best practices at

the same time. You can

enforce selected modules

that conforms to your

shipping needs regardless

if you are a large container

carrier or a local feeder

operator. If the company

wants to improve the

utilization of their existing

container stock, an off-

the-shelf equipment

control system will come

with built in modules for

container tracking,

container forecasting, turn

around analysis, lease

management, and

demurrage detention

billing.

The use of a voyage

calculation software will

provide complete control

over voyage revenues

and expenses to maximize

profitability. It will

automatically calculate

voyage and port cost

related fees and expenses

and reconcile supplier

invoices against actual

volumes and agreed

supplier tariffs. This will

avoid costly mistakes and

helps to ensure an

integrated information

flow between operations

and accounts payable.

Shipping software

provides features that will

allow shipping companies

to automate processes

that have been hard to

control and that still rely

mainly on manual

procedures. An all-in-one

system ensures that all

the important operational

elements in this industry

are managed in the most

efficient way. The primary

objective of having

shipping software in place

is to have a completely

organized shipping

process that increases

productivity and reduces

operational expenses. The

complexity of

transportation processes

to and from any part of

the world should be

reduced considerably for

greater ROI. Shipping

software solutions help in

achieving excellent

customer service as well

as streamline operations.

With adaptable off-the-

organization. Some of

these factors would look

mysteriously

unimportant, but can

have sizable contribution

in the long run.

For instance, there are

many small business

owners who do not feel

the need to acquire a

software package to deal

It’s hard to believe that the

boring calculations still

these organizations.

Without a payroll

software solution, these

companies do not have a

troublesome factor for

both the employees as

well as the government.

However, if you manage

the needs of your

which one enjoy with a

payroll software program.

will not to worry about

your sensitive data falling

into wrong hands. With

which are willing to offer a

free trial or demo before

you shave off your hard

earned money. The

payroll software company

should necessarily have a

good customer support

system in place so that

they cater to your

problems, whenever the

need arises. The best part

is that there are many

payroll software

companies which do not

hesitate from offering

periodic updates of their

product, absolutely free of

cost. This periodic update

will prove to be extremely

helpful, if there are any

changes in the tax plan or

Call Recording –Hardware Solutions VSSoftware Solutions forRecording Phone Calls

In today’s society, just

about anyone can find

numerous benefits from

recording phone

conversations. With the

changing ways and

working habits of today,

call recording has almost

become a requirement for

professionals. The

concept of call recording

is not just for the business

world; even private

individuals find they need

access to this technology

for personal use. There

are two options to

consider when in search

for a good call recording

solution. The choice has

to be made between a

hardware-based solution

and a software-based

solution.

Conventionally, hardware

devices have been used to

record phone

conversations. The most

common type has been

the tape based recorder

and has been around

since tape storage was

introduced. Its primary

benefit has been the ability

to record phone

conversations, especially

the important ones that

cannot be missed.

However, the limited

storage capacity can be a

major disadvantage. The

amount that can be

recorded is limited by the

storage capacity of the

physical tape. This is true

of all call recording

hardware. The capacity of

storage is limited by the

resources manufactured

within the hardware,

especially when it comes

to digital recording

devices.

However, call recording

software is invaluable

because it offers the ability

to record phone

conversations, without

the storage limitations of

traditional devices. The

recordings are then

converted to a

downloadable format for

convenience.

Call recording software is

great for recording phone

calls for:

Business calls

Interviews

Domestic disputes

Journalists and reporters

Attorneys

Law enforcement

Insurance brokers

Financial agents

Many more

Also, because the call is in

digital format, with the

right software, the

conversation can be

amplified, equalized or

even slowed down to get

a clearer understanding of

what was covered.

A good software solution

makes it possible for

professionals to talk to

clients or conduct

interviews using cell

phones to review them

later or store for record

keeping. With the

invention of high-tech

gadgets with internet

capabilities, just about any

mobile device can be used

to save conversations.

Unlike a hardware

solution, one won’t need

separate equipment for

storage purposes. All

recordings are housed on

safe and secure servers

that can be accessed

anytime, anywhere.

Also, when using call

recording software, one

doesn’t have to purchase

additional equipment in

order to record phone

conversations. Both

incoming and outgoing

calls can be recorded

anytime and anywhere.

Imagine the comfort, ease

and versatility combined

in a single package; your

cell phone and call

recording software.

RecordiaPro is the leader

in providing call recording

solutions for those people

who conduct interviews

regularly or those who

need to review recorded

conversations for

business purposes or

record keeping. High

quality recorded phone

conversations can be

downloaded effortlessly in

MP3 format.

Another important point

to consider is the support

offered by a software

based solution.

RecordiaPro has people

standing by to answer

any question that might

come up so that

important conversations

are not missed.

Customers are constantly

amazed with this ground

breaking innovation and

amazing support only

available from

RecordiaPro.

Now that there is a clear

understanding between

the different call recording

solutions, get started with

the best solution for

recording phone

conversations. Visit us to

to record cell phones.

How To Use iPadTransfer Software

If you have recently got

hold of your very own

iPad then you are

probably feeling

immensely proud of

yourself. There is no

denying that the iPad has

revolutionized the digital

entertainment industry. It

is no surprise to now see

many different computer

manufacturers scrambling

to release their own tablet

PCs. To get the most out

of your device you will

need to get hold of iPad

transfer software.

The iPad’s 9.7 inch high

resolution screen make it

the perfect choice for

watching TV shows, HD

movies, music videos,

podcasts, and more. If

you have a large collection

of interesting videos you

would like to watch on

your iPad you will first of

all need to ensure they are

in a suitable format and

only then attempt to

transfer the data to your

device.

To transfer any files from

your iPod, iPhone, Mac,

or other device to your

iPad and vice versa will

require the use of

specialized software. This

can be downloaded from

the Apple store or

through other sites. The

installation process is

straightforward and

before you know it you

can have complete

harmonization between all

your Apple devices.

One of the most popular

options in this field is

called iPad files transfer. If

you have an iPod then

you will be able to transfer

files between this and

your iPad with the

minimal of effort and in

almost instant time. By

using authentic software

the task will be easy and

secure. Even those of us

with limited technological

knowledge should not

have too much difficulty.

Once the software has

been installed all you then

need to do is locate the

files you want to transfer

and then click a button to

start the process. You can

also send documents and

files from your iPad to

your PC using the same

application, but to do this

you will need to highlight

the files in question and

then choose the option of

export to disk.

If you have a Mac as

opposed to a regular PC

you should choose

software that is

compatible. As both Mac

computers and iPads are

made by Apple you

should have no difficulty

in connecting the two

together and sending files

back and forth.

It truly is amazing the

way technology has

changed in just a short

space of time. Even a few

years ago the idea of an

iPad would have seemed

like a far off dream. Now

you can have full

connectivity between all

your digital devices with

iPad transfer software.

iPad transfer software at

only with this apps, all

these needs can be met.

What Can Remote PCAccess Software DoFor You?

Although it may sound

like something out of a

futuristic science fiction

movie, having a remote

PC access software

program isn’t nearly as

intimidating as it sounds.

As a matter of fact, it’s

actually easy to

understand and even

simpler to use, depending

on the software that you

decide on.

Basically, the phrase

‘remote PC access’ refers

to the idea of being able to

use your computer

(desktop, laptop, work

computer) from a

different location. For

example, let’s say that

you’re working on a big

project at work and you’d

like to have access to your

work computer when

you go home. Well, by

using remote PC access

software you’d be able to

do just that. Once you

installed the software on

your work computer, you

could be at your desktop

(or laptop) computer at

home, and once you

logged in it would feel as if

you were looking at the

screen of your work

computer!

And with the

sophistication of today’s

remote pc access

software, you don’t have

to settle for just checking

your email. When you’re

sitting at home and

accessing your computer

at work, you not only

have access to your

email, but you can use the

same files, folders,

documents, network

resources, and even the

computer programs that

are on your work

computer.

And this doesn’t just

apply to using your work

computer from home.

Suppose you’re going on

vacation and you’re

bringing your laptop with

you, but what you really

need is access to your

desktop at home. You

could use a memory stick

and try to download

everything you’ll need

from your desktop to

your laptop, but this can

very tedious. Not only

does it eat up a lot of

memory on your laptop,

but you have to almost

go through the process

again when you get home

and delete all that data

from your laptop so that it

isn’t bogged down with all

of the programs from

your desktop.

And here’s the other

problem with

downloading the

information that you think

you’ll need onto your

laptop. What happens

when you remember to

download 99% of

everything that you need

and forget that one little

file or document that is

crucial to you finishing the

work that you wanted? I’ll

tell you what happens:

everything comes to a

screeching halt! And you

have to wait until you are

physically in front of your

desktop at home again so

you can use that forgotten

file or document.

This entire process of

‘downloading-

transferring- uploading-

deleting’ can be

completely avoided,

though. Because if you’ve

already installed the

software on your home

computer (typically a two

minute process) then

whether you’re a hundred

miles away or a few

thousand miles away on

vacation, it doesn’t matter.

You’ll have complete

access to your home

computer without any of

the hassles of

remembering,

downloading or uploading

anything. The only thing

you have to remember is

your log on code (and

maybe your airplane

tickets if you’re traveling

far away) and you’re

ready to go.

The remote PC access

software gives you all the

convenience and

availability of your favorite

computer without any of

the hassles of copying

files, documents or

programs. It literally is like

carrying your favorite

computer around with

you in your pocket!

Although there are several

different types of remote

PC access software

programs out there, there

are three characteristics

that every good remote

PC program should have.

(If the remote pc access

program you’re

purchasing is missing any

one of these three

characteristics, then run

as fast as you can away

from this software)! To

find out what these three

characteristics are, go to

Remote PC Access
