Thread: What is adapter class?

An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface.

Adapter is a pattern that provides default (often empty) implementation of interface or abstract class. For example MouseAdapter provides empty implementation of MouseListener interface. It is useful because very often you do not really use all methods declared by interface, so implementing the interface directly is very verbose.

I agree with this post.

An adapter is one of the classic design patterns. It is also a class in Java that implements an interface with a set of dummy methods. It lets you rapidly implement an interface.

it is the listener interface toll in html. it is the default implementation to this html coding. adapter classes is very useful in the html and reduce clutter. since the java does't implement the clutter reduce.

The Adapter class provides the default modification of all methods of an interface, we don't need to modify all the methods of the interface so we can say it reduces coding burden. The adapter class is very helpful since it already modifies all the methods of an interface and by implementing the Adapter class, we only need to modify the required methods.

I agree with you this post.

The adapter is one of classic design patterns it is a class implement interface set of dummy methods most commonly adapter used to help you rapidly construct your own listener class field events.

It seems you are answering your own questions. Good going.

An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface. You can define a new class by extending one of the adapter classes and implement only those events relevant to you.
