sleep function not working correctly - function

Question

I am using the code below to make my splash screen
package Splashscreentest;
/*
* SplashDemo.java
*
*/
import java.awt.*;
import java.awt.event.*;
public class Splashscreentest extends Frame implements ActionListener {
static void renderSplashFrame(Graphics2D g, int frame) {
final String[] comps = {"foo", "bar", "baz"};
g.setComposite(AlphaComposite.Clear);
g.fillRect(300,140,400,400);
g.setPaintMode();
g.setColor(Color.BLACK);
g.drawString("Loading "+comps[(frame/5)%3]+"...", 120, 150);
}
public Splashscreentest() {
super("SplashScreen demo");
setSize(3000, 2000);
setLayout(new BorderLayout());
Menu m1 = new Menu("File");
MenuItem mi1 = new MenuItem("Exit");
m1.add(mi1);
mi1.addActionListener(this);
this.addWindowListener(closeWindow);
MenuBar mb = new MenuBar();
setMenuBar(mb);
mb.add(m1);
final SplashScreen splash = SplashScreen.getSplashScreen();
if (splash == null) {
System.out.println("SplashScreen.getSplashScreen() returned null");
return;
}
Graphics2D g = splash.createGraphics();
if (g == null) {
System.out.println("g is null");
return;
}
for(int i=0; i<100; i++) {
renderSplashFrame(g, i);
splash.update();
try {
Thread.sleep(5000);
}
catch(InterruptedException ex) {
}
}
splash.close();
setVisible(true);
toFront();
}
#Override
public void actionPerformed(ActionEvent ae) {
System.exit(0);
}
private static final WindowListener closeWindow = new WindowAdapter(){
#Override
public void windowClosing(WindowEvent e){
e.getWindow().dispose();
}
};
public static void main (String args[]) {
}
}
The splash screen is not remaining on screen for the 5 seconds I would expect it to from the Thread.sleep command I used. The image for my splash screen is in this project within source packages

You're calling Thread.Sleep within the for loop. Change it to
for(int i=0; i<100; i++) {
renderSplashFrame(g, i);
splash.update();
try {
Thread.sleep(50);
}
catch(InterruptedException ex) {
}
}
