frogger game help

[froggerhelp]

we're making the game frogger using java, and we can't get our KeyListener to work. here is what we have so far:

ublic class Frogger extends GraphicsProgram implements KeyListener
{
// instance variables
private Room myRoom;


public void init()
{
System.out.println("constructed frogger");
myRoom = new Room (400, 350, getGCanvas ());
this.setFocusable(true);
this.addKeyListener(this);


public void keyTyped(KeyEvent e)
{
System.out.println(e.getKeyCode());
}

public void keyDown(KeyEvent e)
{
System.out.println("key down");
}

public void keyPressed (KeyEvent e)
{
System.out.println("key pressed");
if (evt.getKeyCode() == KeyEvent.VK_DOWN)
{
myRoom.keyPressed(evt);
}

if (evt.getKeyCode() == KeyEvent.VK_UP)
{
myRoom.keyPressed(evt);
}

if (evt.getKeyCode() == KeyEvent.VK_LEFT)
{
myRoom.keyPressed(evt);
}

if (evt.getKeyCode() == KeyEvent.VK_RIGHT)
{
myRoom.keyPressed(evt);
}
}


public void run ()
{
myRoom.run ();
System.out.println("WTM");
}


}
