public abstract class KeyAdapter extends Object implements KeyListener
 Extend this class to create a KeyEvent listener
 and override the methods for the events of interest. (If you implement the
 KeyListener interface, you have to define all of
 the methods in it. This abstract class defines null methods for them
 all, so you can only have to define methods for events you care about.)
 
 Create a listener object using the extended class and then register it with
 a component using the component's addKeyListener
 method. When a key is pressed, released, or typed,
 the relevant method in the listener object is invoked,
 and the KeyEvent is passed to it.
