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

public class LogoAnimator extends JPanel
                          implements ActionListener {
   protected ImageIcon images[];
   protected int totalImages = 30,
                 currentImage = 0,
                 animationDelay = 50// 50 millisecond delay
   protected Timer animationTimer;

   public LogoAnimator()
   {
      setSizegetPreferredSize() );

      images = new ImageIcontotalImages ];

      for int i = 0; i < images.length; ++i 
         images=
            new ImageIcon"images/java" + i + ".gif" );

      startAnimation();
   }

   public void paintComponentGraphics g )
   {
      super.paintComponent);

      if imagescurrentImage ].getImageLoadStatus() ==
           MediaTracker.COMPLETE ) {
         imagescurrentImage ].paintIconthis, g, 0);
         currentImage = currentImage + % totalImages;
      }
   }

   public void actionPerformedActionEvent e )
   {
      repaint();
   }

   public void startAnimation()
   {
      if animationTimer == null ) {
         currentImage = 0;  
         animationTimer = new TimeranimationDelay, this );
         animationTimer.start();
      }
      else  // continue from last image displayed
         if ! animationTimer.isRunning() )
            animationTimer.restart();
   }

   public void stopAnimation()
   {
      animationTimer.stop();
   }

   public Dimension getMinimumSize()
   
      return getPreferredSize()
   }

   public Dimension getPreferredSize()
   {
      return new Dimension16080 );
   }

   public static void mainString args[] )
   {
      LogoAnimator anim = new LogoAnimator();

      JFrame app = new JFrame"Animator test" );
      app.getContentPane().addanim, BorderLayout.CENTER );

      app.addWindowListener(
         new WindowAdapter() {
            public void windowClosingWindowEvent e )
            {
               System.exit);
            }
         }
      );

      // The constants 10 and 30 are used below to size the
      // window 10 pixels wider than the animation and
      // 30 pixels taller than the animation. 
      app.setSizeanim.getPreferredSize().width + 10,
                   anim.getPreferredSize().height + 30 );
   }
