Directory "StarApplet 1"

You can now define an applet that draw stars:

import javax.swing.*;
import java.awt.*;

@SuppressWarnings("serial")
public class StarApplet extends JApplet {
// Initialize the applet
@Override
public void init() {
StarPane pane = new StarPane(); // Pane containing stars
getContentPane().add(pane); // BorderLayout.CENTER is

default position
}
