AN APPLET SKELETON

Java:Applet Skeleton

Most of the applets override a set of methods that controls its execution.

• Four of these methods init( ), start( ), stop( ), and destroy( ) are defined by Applet.
• paint( ), is defined by the AWT Component class.

These five methods can be assembled into the skeleton shown here: 

// An Applet skeleton.

import java.awt.*;

import javax.swing.*;

/*

<applet code="AppletSkel" width=300 height=100>

</applet>

*/

public class AppletSkel extends JApplet {

  // Called first.

  public void init() {

    // initialization

  }

  /* Called second, after init().  Also called whenever

     the applet is restarted. */

  public void start() {

    // start or resume execution

  }

  // Called when the applet is stopped.

  public void stop() {

    // suspends execution

  }

  /* Called when applet is terminated.  This is the last

     method executed. */

  public void destroy() {

    // perform shutdown activities

  }

  // Called when an applet's window must be restored.

  public void paint(Graphics g) {

    // redisplay contents of window

  }

}

Although this skeleton does not do anything,it can be compiled and run.When run,it generates the following window when viewed with an appletviewer:
