Main program start before splash screen, help

Question

hi:
below is the splash screen code:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.io.PrintStream;
import java.util.Random;
class Splash extends JWindow {
     public Splash(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();
                         // can catch InvocationTargetException
                         // can catch InterruptedException
          setVisible(true);
          Thread splashThread = new Thread(waitRunner, "SplashThread");
          splashThread.start();
below is the constructor that started the splash and the main:
public static void main(String args[])
PictureViewer PV = new PictureViewer();
standaloneApp = true;
splash Splash sw = new Splash("prestigestetho.gif",null, 5000);
the splash appear just fine, the problem is that it appears after
my main program appear first.
I try to shift the priority of splash, which is sw first and then PV,
in that case the splash screen appear first then PV, but this time PV
stay in front of sw makes it totally not viewable.
is there any method to make splash screen appear first and on the screen you can see the process of main program starting up (for example
: loading this ...., loading that.....) something like acrobat reader's
startup screen, and then splash screen disappear and then main program
pop up.

okay, I got it, it's under SwingSet2.java the related code is as follow:
// Used only if swingset is an application
private JFrame frame = null;
private JWindow splashScreen = null;
// The tab pane that holds the demo
private JTabbedPane tabbedPane = null;
private JEditorPane demoSrcPane = null;
private JLabel splashLabel = null;
* SwingSet2 Constructor
public SwingSet2(SwingSet2Applet applet, GraphicsConfiguration gc) {
// Note that the applet may null if this is started as an application
     this.applet = applet;
// Create Frame here for app-mode so the splash screen can get the
// GraphicsConfiguration from it in createSplashScreen()
if (!isApplet()) {
frame = createFrame(gc);
// setLayout(new BorderLayout());
     setLayout(new BorderLayout());
// set the preferred size of the demo
     setPreferredSize(new Dimension(PREFERRED_WIDTH,PREFERRED_HEIGHT));
// Create and throw the splash screen up. Since this will
// physically throw bits on the screen, we need to do this
// on the GUI thread using invokeLater.
createSplashScreen();
// do the following on the gui thread
     SwingUtilities.invokeLater(new Runnable() {
     public void run() {
          showSplashScreen();
initializeDemo();
     preloadFirstDemo();
     // Show the demo and take down the splash screen. Note that
     // we again must do this on the GUI thread using invokeLater.
     SwingUtilities.invokeLater(new Runnable() {
     public void run() {
          showSwingSet2();
          hideSplash();
     // Start loading the rest of the demo in the background
     DemoLoadThread demoLoader = new DemoLoadThread(this);
     demoLoader.start();
* Show the spash screen while the rest of the demo loads
public void createSplashScreen() {
     splashLabel = new JLabel(createImageIcon("Splash.jpg", "Splash.accessible_description"));
     if(!isApplet()) {
     splashScreen = new JWindow(getFrame());
     splashScreen.getContentPane().add(splashLabel);
     splashScreen.pack();
     Rectangle screenRect = getFrame().getGraphicsConfiguration().getBounds();
     splashScreen.setLocation(
screenRect.x + screenRect.width/2 - splashScreen.getSize().width/2,
          screenRect.y + screenRect.height/2 - splashScreen.getSize().height/2);
public void showSplashScreen() {
     if(!isApplet()) {
     splashScreen.show();
     } else {
     add(splashLabel, BorderLayout.CENTER);
     validate();
     repaint();
* pop down the spash screen
public void hideSplash() {
     if(!isApplet()) {
     splashScreen.setVisible(false);
     splashScreen = null;
     splashLabel = null;
