The KeyAdapter class implements the methods of KeyListener with empty functions. It may be easier for you to extend KeyAdapter, overriding only those methods you are interested in, than to implement KeyListener and provide the empty functions yourself.
public abstract class java.awt.event.KeyAdapter
extends java.lang.Object

// Instance Methods

public void keyReleased (KeyEvent e);
public void keyTyped (KeyEvent e);
