Java Applet Example

To run applets we use appletviewer .

An appletviewer is command line program to invoke an applet program from command line.

Here we will see how to run applet from applet viewer

Example : Write a simple applet program to print “ Hello Students”

import java.applet.Applet;
import java.awt.Graphics;

/* 
<applet code="APdemo.class" width="300" height="300"> 
</applet> 
*/

public class APdemo extends Applet {
    String s = "Hello Students";
    public void paint(Graphics g) {
        g.drawString(s, 100, 100); // print string at 100*100 pixel location
    }

}

import java.applet.Applet;

import java.awt.Graphics;

</applet>

public class APdemo extends Applet {

String s = "Hello Students";

public void paint(Graphics g) {

g.drawString(s, 100, 100); // print string at 100*100 pixel location

}

Compile Save & Run: Save this file with APDemo.java name.

Compile : javac APDemo.java

Run: appletviewer ApDemo.java

Example : Write a simple applet program to print “ Hello Students” and show the how init(), start() ,paint(), stop() and destroy() method executes in a sequence.

import java.applet.Applet;
import java.awt.Graphics;

/* 
<applet code="APDemo1.class" width="300" height="300"> 
</applet> 
*/

public class APDemo1 extends Applet {
    String s = "Hello Students";

    public void init() {
        System.out.println("Inside init method");

    }
    public void start() {
        System.out.println("Inside start method");
    }

    public void paint(Graphics g) {
        System.out.println("Inside paint method");
        g.drawString(s, 100, 100); // print string at 100*100 pixel location
    }
    public void stop() {
        System.out.println("Inside stop method");
    }
    public void destroy() {
        System.out.println("Inside destroy method");
    }

}

import java.applet.Applet;

import java.awt.Graphics;

</applet>

public class APDemo1 extends Applet {

String s = "Hello Students";

public void init() {

System.out.println("Inside init method");

}

public void start() {

System.out.println("Inside start method");

}

public void paint(Graphics g) {

System.out.println("Inside paint method");

g.drawString(s, 100, 100); // print string at 100*100 pixel location

}

public void stop() {

System.out.println("Inside stop method");

}

public void destroy() {

System.out.println("Inside destroy method");

}

Note: In an applet program first init() method executes then start() method. After start(), paint() executes.

Compile Save & Run: Save this file with ApDemo1.java name.

Compile : javac APDemo1.java

Run: appletviewer APDemo1.java

After running applet we will see following output in console

Inside init method
Inside start method
Inside paint method
Inside stop method
Inside destroy method

Inside init method

Inside start method

Inside paint method

Inside stop method

Inside destroy method
