Applet Life Cycle

All applets have the following four lifecycle methods:

init -> Applet can initialize itself.
start ->Applet can start running.
stop ->Applet can stop running.
destroy ->Applet can perform a final cleanup, in preparation for being unloaded.

Java Example Program / Sample Source Code

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

public class AppletLifecycle extends Applet {
StringBuffer buffer;

public void init() {
    buffer = new StringBuffer();
    addItem("initializing... ");
}

public void start() {
    addItem("starting... ");
}

public void stop() {
    addItem("stopping... ");
}

public void destroy() {
    addItem("preparing for unloading...");
}

private void addItem(String newWord) {
    System.out.println(newWord);
    buffer.append(newWord);
    repaint();
}

public void paint(Graphics g) {
    // Drawing a Rectangle around the applet's display area.
    g.drawRect(0, 0, getWidth() - 1, getHeight() - 1);
    // Drawing the current string inside the rectangle.
    g.drawString(buffer.toString(), 5, 15);
}
}
