changing the Frame to "full screen" mode

Well, this sets the size of the frame to be equal to the size of screen.
While I want it to appear as a powerpoint presentation appears; the bar at the top (which has the minimize/maximize/close buttons) and the control panel at the bottom also should vanish.

Thnx

Here is an example that you may want:

import java.awt.*;

public class TestFrame extends Frame {
   public TestFrame() {
      super();
      setUndecorated(true);
      setLocation(0, 0);
      setSize(Toolkit.getDefaultToolkit().getScreenSize());

      // add components here
      show();
  }

   public static void main(String[] args) {
      new TestFrame();
   }
}

The setUndecoreated() method removes the title bar from the Frame, but this method is only available in SDK 1.4.

Oops.... yongsing is right.

In SDK1.3 or below, you may need to be extending Window rather than Frame to achieve your goal.

Here is an example:

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);
   }
}

JDK 1.4 comes with such facilities.
