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.
Java programming language also have a design adapter named adapter. The Adapter design pattern is also used to join to two unrelated interfaces so that can work together. The joint between these two interfaces is termed as Adapter. This is something like the conversion of interface of one class into interface. This is done by using an Adapter.
