Splashscreen problem...

Question

Hi, I have a class that makes splash screen (found it somewhere online and then edited for my purpose). Now this only works at the beginning of a GUI application. In my specific program I need to make splash screens while the GUI is running. Here is the code for the splash screen class I used:
// Splash Screen Class:
class SplashScreen extends JWindow
    // Constructor for time:
    public int duration;
    public SplashScreen (int d)
        duration = d;
    // Splash Screen method:
    public void showSplash (BufferedImage source)
        // Initialization and background:
        JPanel content = (JPanel) getContentPane ();
        content.setBackground (Color.white);
        // Set the window's bounds, centering the window
        int width = source.getWidth ();
        int height = source.getHeight ();
        Dimension screen = Toolkit.getDefaultToolkit ().getScreenSize ();
        int x = (screen.width - width) / 2;
        int y = (screen.height - height) / 2;
        setBounds (x, y, width, height);
        // Build the splash screen
        JLabel image = new JLabel (new ImageIcon (source));
        content.add (image);
        content.setBorder (BorderFactory.createLineBorder (Color.black, 2));
        // Display it
        setLocation (8, 8);
        setVisible (true);
        // Wait a little while, maybe while loading resources
        try
            Thread.sleep (duration);
        catch (Exception e)
        setVisible (false);
    // Show splash screen for a while, then close:
    public void showSplashAndExit (BufferedImage source)
        showSplash (source);
// To call the Splash Screen I use the following:
        try
            BufferedImage Introduction1 = ImageIO.read (new File ("IntroductionImages/Introduction1.jpg"));
            SplashScreen splash1 = new SplashScreen (2000);
            splash1.showSplashAndExit (Introduction1);
        catch (IOException e)
        }Anyways that works for the introduction only(while the GUI application is being loaded). But it does not work while the main frame is running. The only way I could do this is by using JinternalFrame. So basically, I want to make a similar splash screen class using JInternalFrame so that the splash screen will work WHILE the GUI application is running. If there is another way to do the above, I would highly appreciate your advice. If not, then can anybody tell me how I can manipulate this same class to be used for JInternalFrame. Any help would be greatly appreciated. Thanks!

I see a problem with your potentially putting the EDT thread to sleep by calling Thread(sleep). Have you tried to use a Swing Timer instead?
