Cannot find symbol error

[Empyrean]

Okay, I'm getting an error in the line:

public class Graphics extends JFrame implements KeyListener
{

I get the error Cannot Find Symbol

The code works fine when I take out the implements KeyListener, but when I put it in it won't compile.

if you implement KeyListener your code must contain the methods keyPressed, keyReleased and keyTyped

It can help too to do this:

import java.awt.KeyListener;
