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.

Answer / khan
In java programming language, adapter class is used to
implement an interface having a set of dummy methods. The
developer can then further subclass the adapter class so
that he can override to the methods he requires.
Implementing an interface directly, requires to write all
the dummy methods. In general an adapter class is used to
rapidly construct your own Listener class to field events.

Answer / akki
Adapter classes are empty implementation of the methods provided by their corresponding interfaces.
if we implements the interface we have to give definition to all methods of interface.
but if we extend adapter class then we will require to define method which we gonna use in our code

Answer / barkha
An adapter class is a class that provides a dummy (empty)
implementation for an interface. That way someone who wants
to implement the interface but does not want or does not
know how to implement all methods, can use the adapter class
instead, and only override the methods he is interested in.
