Question

If anyone can point me in the right direction.
Here is the code I have so far.

//UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setUndecorated(true);//To remove the bars around the frame.
frame.setResizable(false);//resizability causes unsafe operations.

frame.validate();

//actually applies the fullscreen.
GaphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(frame);

Answer 1

There are three complex example you may interested in oracle tutorials.

Do you want to use high-performance
graphics in the Java development
environment? Have you always wanted to
program a game, but your images
wouldn’t move fast enough? Has your
slide show program not worked properly
because you had no control over the
user’s display resolution? If you’ve
been asking any of these questions,
then the full-screen exclusive mode
API, introduced in release 1.4, may be
what you’re looking for.

---

CapabilitiesTest demonstrates the different buffering capabilities
available for the machine on which it
is run.

---

DisplayModeTest shows a Swing application that uses passive
rendering. If full-screen exclusive
mode is available, it will enter
full-screen exclusive mode. If display
mode changes are allowed, it allows
you to switch between display modes.

---

MultiBufferTest enters full-screen mode and uses multi-buffering through an active render loop.

Take a look at this:

and this:

EDIT:

Here is a sample app does what you want:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;


public class DisplayModeChanger extends JFrame {

    private GraphicsDevice device;
    private static JButton changeDM = new JButton("800X600 @ 32 BIT 60HZ");
    private boolean isFullScreenSupported = false;

    public DisplayModeChanger(final GraphicsDevice device) {

        this.device = device;

        setDefaultCloseOperation(EXIT_ON_CLOSE);

        changeDM.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                DisplayMode dm = new DisplayMode(800, 600, 32, 60);
                device.setDisplayMode(dm);
                setSize(new Dimension(dm.getWidth(), dm.getHeight()));
                validate();
            }
        });

    }

    public void goFullScreen() {
        isFullScreenSupported = device.isFullScreenSupported();
        setUndecorated(isFullScreenSupported);
        setResizable(!isFullScreenSupported);
        if (isFullScreenSupported) {
            device.setFullScreenWindow(this);
            validate();
        } else {
            pack();
            setVisible(true);
        }
    }

    public static void main(String[] args) {
        GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice defaultScreen = env.getDefaultScreenDevice();
        DisplayModeChanger changer = new DisplayModeChanger(defaultScreen);
        changer.getContentPane().add(changeDM);
        changer.goFullScreen();
    }
}
