Java Tips - How to implement a splash screen for an application

This Java Swing tip illustrates a method of implementing your own splash screen. This is a simple application to show a title screen in the center of the screen for the amount of time given in the constructor. This class includes a sample main() method to test the splash screen, but it's meant for use with other applications.


import java.awt.*;

import javax.swing.*;



public class SplashScreen extends JWindow {

    

    private int duration;

    

    public SplashScreen(int d) {

        duration = d;

    }

    

    // A simple little method to show a title screen in the center

    // of the screen for the amount of time given in the constructor

    public void showSplash() {

        

        JPanel content = (JPanel)getContentPane();

        content.setBackground(Color.white);

        

        // Set the window's bounds, centering the window

        int width = 450;

        int height =115;

        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 label = new JLabel(new ImageIcon("java-tip.gif"));

        JLabel copyrt = new JLabel

                ("Copyright 2002, O'Reilly & Associates", JLabel.CENTER);

        copyrt.setFont(new Font("Sans-Serif", Font.BOLD, 12));

        content.add(label, BorderLayout.CENTER);

        content.add(copyrt, BorderLayout.SOUTH);

        Color oraRed = new Color(156, 20, 20,  255);

        content.setBorder(BorderFactory.createLineBorder(oraRed, 10));

        

        // Display it

        setVisible(true);

        

        // Wait a little while, maybe while loading resources

        try { Thread.sleep(duration); } catch (Exception e) {}

        

        setVisible(false);

        

    }

    

    public void showSplashAndExit() {

        

        showSplash();

        System.exit(0);

        

    }

    

    public static void main(String[] args) {

        

        // Throw a nice little title page up on the screen first

        SplashScreen splash = new SplashScreen(10000);



        // Normally, we'd call splash.showSplash() and get on 

        // with the program. But, since this is only a test...

        splash.showSplashAndExit();

        

    }

}
