Is there any way to create a full-screen (non-windowed) application in Java?

No because in Microsoft Windows the "Start
bar" remains top-level and overlaps
with your Window.
Yes and no.
Yes because Java has components that are non-windowed. Ironically these are called Window (AWT) and JWindow (Swing).
Other platforms may have the same problem. Note that you may be able to get a truly full-screen application by using JNI to call native methods on your platform, but that kills portability of your application.
Here is the AWT code to make a Window as large as the screen.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class FullscreenWindowApp extends Window {
private Button button;
public FullscreenWindowApp() {
super(new Frame());
button = new Button("Close");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}});
setLayout(new FlowLayout());
add(button);
//get the screen size
Dimension screenSize =
Toolkit.getDefaultToolkit().getScreenSize();
//sets the location of the window to top left of screen
setBounds(0,0,screenSize.width, screenSize.height);
}
public static void main(String[] args) {
new FullscreenWindowApp().setVisible(true);
}
}
The Swing code is nearly the same, using JWindow instead of Window,
