Is it possible to have a program start with a splash screen?

Question

Would it be possible to have a program show a splash screen while loading with Java's latest release 1.4.0 ?
If it is possible, could anybody explain me how.. and maybe show me a little example? :)
Thanks in advance

Answer 1

I just implemented this with one of my applications.
I wrote a class which extends JWindow and adds a JLabel icon to the contentPane.
The class containing the main method instantiates this class, makes the window visible, wait's some time and deletes the window:
Through the Dimension object I calculate the center of the screen
=> Splash screen
import javax.swing.*;
import java.awt.*;
class Splash extends JWindow
JPanel pane;
public Splash()
super();
setBounds(300, 225, 300, 200);
pane = new JPanel();
ImageIcon image = new ImageIcon("logo.jpg"); //Splash logo
Dimension dim = this.getToolkit().getScreenSize();
int height = (int) dim.getHeight() / 2;
int width = (int) dim.getWidth() / 2;
int iconheight = image.getIconHeight();
int iconwidth = image.getIconWidth(); // Center of Screen
int x = width - (iconwidth / 2);
int y = height - (iconheight / 2);
setLocation(x, y);
JLabel label = new JLabel(image);
pane.add(label);
setContentPane(pane);
pack();
=> "Main Method"
import util.*;
import app.*;
import java.awt.*;
import javax.swing.*;
public class Main
public static void main(String[] args)
Splash splash = new Splash();
splash.setVisible(true);
try
Thread.sleep(10000);
catch (InterruptedException e)
splash.setVisible(false);
splash = null;
