Java Language rule are such that we must implement all the
methods of an interface even if we put them into empty
braces.i.e. we must override all the methods declared in
the interface.
But we can create our classes as subclasses of one of
the adapter classes, then we need to override only some of
the methods we need. i.e, An adapter classes provide empty
implementation of all methods declared in an EventListener
interface.
