class
(overriding only the methods of interest).
The listener object created from that class is then registered with a
component using the component's addKeyListener
method. A keyboard event is generated when a key is pressed, released,
or typed. The relevant method in the listener
object is then invoked, and the KeyEvent
is passed to it.
