Applet lifecycle methods

In this example we shall show you the Applet lifecycle methods. A Java applet is a special kind of Java program that a browser enabled with Java technology can download from the internet and run. An applet is typically embedded inside a web page and runs in the context of a browser. An applet must be a subclass of the java.applet.Applet class. The Applet class provides the standard interface between the applet and the browser environment. The Applet lifecycle methods are the ones below:

• init() API method is called by the browser or applet viewer to inform this applet that it has been loaded into the system.
• start() API method is called by the browser or applet viewer to inform this applet that it should start its execution.
• stop() API method is called by the browser or applet viewer to inform this applet that it should stop its execution.
• destroy() API method is called by the browser or applet viewer to inform this applet that it is being reclaimed and that it should destroy any resources that it has allocated.
• paint(Graphics g) API method is used to paint the container of the applet. This forwards the paint to any lightweight components that are children of this container,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;

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

public class AppletLifecycleMethods extends Applet {
	
	private static final long serialVersionUID = 5872447536017036208L;

	// Called by the browser or applet viewer to inform
	// this applet that it has been loaded into the system.
    public void init() {
    }

    // Called by the browser or applet viewer to inform
    // this applet that it should start its execution.
    public void start() {
    }

    // Called by the browser or applet viewer to inform
    //this applet that it should stop its execution.
    public void stop() {
    }

    // Called by the browser or applet viewer to inform
    // this applet that it is being reclaimed and that it
    // should destroy any resources that it has allocated.
    // The stop method will always be called before destroy. 
    public void destroy() {
    }

    // Paints the container. This forwards the paint to any
    // lightweight components that are children of this container.
    public void paint(Graphics g) {
    }

}
