Here is the code I have.  Basically all I want to do is change the
background of the frame to black when I click the mouse (mouseClicked)
and change it back to white when I release the mouse (mouseReleased).
I can't access frame directly to do frame.setBackground(Color.BLACK),
and that is where I am stuck.

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

public class BackgroundChange extends JFrame
{
	public BackgroundChange()
	{

	}

	public static void main(String[] args)
	{
		BackgroundChange frame = new BackgroundChange();
		frame.setTitle("Background Change");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(300,300);
		frame.setVisible(true);
		frame.setBackground(Color.WHITE);
	}
}

class BackgroundChangePanel extends BackgroundChange implements
MouseListener
{
	public BackgroundChangePanel()
	{
		addMouseListener(this);
	}

	public void mouseClicked(MouseEvent e)
	{

	}

	public void mouseEntered(MouseEvent e)
	{

	}

	public void mouseExited(MouseEvent e)
	{

	}

	public void mouseReleased(MouseEvent e)
	{
		
	}
	
	public void mousePressed(MouseEvent e)
	{
		
	}
}
