public abstract class KeyAdapter extends Object implements KeyListener
Extend this class to create a
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
method. When a key is pressed, released, or typed,
the relevant method in the listener object is invoked,
KeyEvent is passed to it.
