Splash Screen Code

Question

I couldn't find any splash screen code I like on the Internet, so I made this. I'm just posting this in case someone else finds it useful.
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Toolkit;
import java.io.File;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JWindow;
* The worst Splash Screen. Ever.
* @author George Wyatt
* @version 0.1
public class SplashScreen extends JWindow {
      * Holds a static instance of this class.
    static private class Holder
       static protected final SplashScreen manager = new SplashScreen();
      * Hides the splash.
     public static void hideSplash() {
          SplashScreen.Holder.manager.setVisible(false);
      * Changes the image file to be splashed.
      * @param filename  the name of the file
     public static void setFilename(String filename) {
          if (!new File(filename).exists()) {
               System.out.println("File doesn't exist!");
               return;
          SplashScreen.Holder.manager.filename = filename;
      * Displays the splash. Should display above other windows.
     public static void showSplash() {
          SplashScreen ss = SplashScreen.Holder.manager;
          if (ss.filename == null) {
               System.out.println("No file to display!");
               return;
          if (!new File(ss.filename).exists()) {
               System.out.println("File doesn't exist!");
               return;
        JLabel l = new JLabel(new ImageIcon(ss.filename));
        ss.getContentPane().add(l, BorderLayout.CENTER);
        ss.pack();
        Dimension screenSize =
          Toolkit.getDefaultToolkit().getScreenSize();
        Dimension labelSize = l.getPreferredSize();
        ss.setLocation(screenSize.width/2 - (labelSize.width/2),
                    screenSize.height/2 - (labelSize.height/2));
        screenSize = null;
        labelSize = null;
          ss.setVisible(true);
          ss.repaint();
          ss.toFront();
     private String filename;
}
