As far as I know, this code is supposed to draw a black circle, and then slowly move it across the screen.. only problem is.. it doesn't move.. and on my computer, if i extend the applets screen, the ball dissapears and moves back if i shrink the applet back down.. if someone can help me id appreciate it..

// This applet displays a message moving horizontally
// across the screen.

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

public class Banner extends JApplet

  public void init()
    Container c = getContentPane();

  public void paint(Graphics g)
    int x = 10;
    int y = 10;
    g.fillOval(x, y, 20, 20);
