// This is a sample program to test the eclipse launcher.
// The program looks for the "-endsplash" argument and its
// command string. To simulate initialization, the program
// sleeps for 10 seconds.
package org.eclipse.core.launcher;import java.io.*;
public class Main {private static String splashCmd = null;public static void main( String args[] ) {    System.out.println( "Eclipse: Program started." );    // Extract the command to end the splash window. 
    for (int index = 0; index < args.length; index++)
    {
        System.out.println( "    args[" + index + "] = '" + args[index] + "'" );
        if (args[ index ].equals( "-endsplash" ) && (index+1) < args.length)
        {
            splashCmd = args[ index + 1 ];
        }
    }    // Perform the initialization of eclipse.
    try {
        Thread.sleep( 5000 );
    }
    catch (Exception e) {}
    System.out.println( "Eclipse: Initialization complete!" );    // Initialization is complete so execute the end splash command.
    if (splashCmd != null) {
        try {
            Runtime.getRuntime().exec( splashCmd );
        }
        catch (Exception e) {}
    }    // Perform the actual work of eclipse.
    try {
        Thread.sleep( 10000 );
    }
    catch (Exception e) {}
    System.out.println( "Eclipse: Program is terminating!" );
}
}

class SplashWindow3 extends JWindow
{
    public SplashWindow3(String filename, Frame f, int waitTime)
    {
        super(f);
        JLabel l = new JLabel(new ImageIcon(filename));
        getContentPane().add(l, BorderLayout.CENTER);
        pack();
        Dimension screenSize =
          Toolkit.getDefaultToolkit().getScreenSize();
        Dimension labelSize = l.getPreferredSize();
        setLocation(screenSize.width/2 - (labelSize.width/2),
                    screenSize.height/2 - (labelSize.height/2));
        addMouseListener(new MouseAdapter()
            {
                public void mousePressed(MouseEvent e)
                {
                    setVisible(false);
                    dispose();
                }
            });
        final int pause = waitTime;
        final Runnable closerRunner = new Runnable()
            {
                public void run()
                {
                    setVisible(false);
                    dispose();
                }
            };
        Runnable waitRunner = new Runnable()
            {
                public void run()
                {
                    try
                        {
                            Thread.sleep(pause);
                            SwingUtilities.invokeAndWait(closerRunner);
                        }
                    catch(Exception e)
                        {
                            e.printStackTrace();
                            // 能够捕获InvocationTargetException
                            // 能够捕获InterruptedException
                        }
                }
            };
        setVisible(true);
        Thread splashThread = new Thread(waitRunner, "SplashThread");
        splashThread.start();
    }
}

                        }
                }
            };
        setVisible(true);
        Thread splashThread = new Thread(waitRunner, "SplashThread");
        splashThread.start();
    }
}这样就可以了！哈哈！
