How to make a splash screen for GUI?

Question

Hi there I'm new to GUIs in Java and was trying to make a splash screen or an image appear for 3 seconds. Then after that it it will go onto my main program. Does anyone have an ideas how to do this or can link me to any tutorials?

So far I have done this but not sure where to go from here.

public static void main(String[] args)
{
    splashInit();           // initialize splash overlay drawing parameters
    appInit();              // simulate what an application would do 
}

Simplest one , is to create JFrame and add your screen on it then use Thread.Sleep(long millies)

Try this code:

JWindow window = new JWindow();
window.getContentPane().add(
    new JLabel("", new ImageIcon(new URL("http://docs.oracle.com/javase/tutorial/uiswing/examples/misc/SplashDemoProject/src/misc/images/splash.gif")), SwingConstants.CENTER));
window.setBounds(500, 150, 300, 200);
window.setVisible(true);
try {
    Thread.sleep(5000);
} catch (InterruptedException e) {
    e.printStackTrace();
}
window.setVisible(false);
JFrame frame = new JFrame();
frame.add(new JLabel("Welcome"));
frame.setVisible(true);
frame.setSize(300,100);
window.dispose();

Or you can Create a Splash Screen by using SplashScreen class

Answer 3

There's a pretty descent beginners tutorial here which explains how to create such a screen, with a step by step guide how to get there. Wouldn't hurt to Google first, I'd say.

This works fine for me.The functions such as getScreenSize() ,getWidth() and getHeight() can be replaced by own values.

public class splash extends JWindow 
{
  public splash()
  {
     JWindow j=new JWindow();

     Dimension d=Toolkit.getDefaultToolkit().getScreenSize();

     Icon img= new ImageIcon(this.getClass().getResource("2.jpg"));
     JLabel label = new JLabel(img);
     label.setSize(200,300);
     j.getContentPane().add(label);
     j.setBounds(((int)d.getWidth()-722)/2,((int)d.getHeight()-401)/2,722,401);
     j.setVisible(true);
     try
     {
        Thread.sleep(6000);
     }
    catch(InterruptedException e)
    {
        e.printStackTrace();
    }
     j.setVisible(false);

  }
  public static void main(String[] args)
  {
    splash s=new splash();
  }
}
