JFrame help

-----------------------------------

I am very new to java and it is very confusing. I started first with turing and now im onto java so i took this course. One of our labs was to create a program to maximize the size of the frame and put it at the top of the screen.

Here is what i have so far.


/**
 * A JFrame that can double in width.
 */

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

public class MaxWindow extends JFrame {
   
  Dimension d= Toolkit.getDefaultToolkit().getScreenSize();
  int screenWidth= (int) d.getWidth();
  int screenHeight= (int) d.getHeight();
  
  public MaxWindow(String t) {
    super (t);
  }
  
  public MaxWindow() {
    // this automatically calls super().
  }
  
  public void maxWidth() {
    setSize (screenWidth, getHeight());
  }
  
  public void maxHeight() {
  
  }
}


NOTE: I am using DrJava to write and test all this. Any help would be great.

i do not think that is what he whonts, b/c he side maximised like the window mode. but i will post the fullscreen code just the same:

class from my FP that dose fullscreen:


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

/**
 *a fullscreen frame to be used for the game
 *@author Dan
 */
public class QFTBFrame extends JFrame
{	
	private GraphicsEnvironment env;
	private GraphicsDevice device;
	private boolean isFullScreen;
	
	/**
	 *a new frame that will be fullscreen if the system suports it
	 */
	public QFTBFrame()
	{
		super();
		
		env = GraphicsEnvironment.getLocalGraphicsEnvironment();
		device = env.getDefaultScreenDevice();
		
		isFullScreen = device.isFullScreenSupported();

		if(isFullScreen)
		{
			setUndecorated(true);
        	setResizable(false);
    		device.setFullScreenWindow(this);
		}
		else
		{
			setUndecorated(false);
        	setResizable(true);
			System.out.println("Error: your system dose not sport fullscreen, trying normal size...");
		}
	}
	
	/**
	 *should take the system out of fullscreen mode (untested)
	 */
	public void end()
	{
		if(isFullScreen)
		{
			device.setFullScreenWindow(null);
		}
	}
}



fullscreen is a bit bugy esepltay when using it with GUIs like awt and swing and it dose not work on all systems.

-----------------------------------

It's not the fullscreen i want.  I need to write a class that has a method that can maximize the width and another method to maximize the height. We are learning all this in a class im taking but i find java very confusing.
