给你个例子,不是我做的.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;public class CoverFrame extends JFrame
{
   public CoverFrame(){
       Dimension dimension = getToolkit().getScreenSize();
       setBounds((dimension.width - 640) / 2,(dimension.height - 480) / 2,640,480);
       addWindowListener(new WindowAdapter(){public void windowClosing(WindowEvent windowevent){System.exit(0);}});
   }
   public static void main(String argv[]){
       class Cover extends Window{
           public Cover(JFrame f){
               super(f);
               Dimension dimension = getToolkit().getScreenSize();
               setBounds((dimension.width - 320) / 2,(dimension.height - 240) / 2,320,240);
               java.net.URL imgURL = getClass().getResource("PICS/COVER.jpg");
               ImageIcon icon=new ImageIcon(imgURL);
               add(new JLabel(icon));
           }
       }
       final CoverFrame l=new CoverFrame();
       final Cover cover=new Cover(l);
       cover.show();
       javax.swing.Timer timer=new Timer(5000,new ActionListener(){
           public void actionPerformed(ActionEvent e){
               cover.dispose();
               ((Timer)e.getSource()).stop();
               l.show();
           }
       });
       timer.start();
   }
}
