Wait, what? When you posted this and read this again through the eyes of the OP, do you think he completely understands the Adapter pattern?

Forget the OP, I don't even understand the answer.

There is more than one meaning, but the most common meaning in Java is a class that provides empty implementations of all the methods in an interface. Users of the API can avoid clutter in their code by extending the adapter class instead of implementing the interface.

A couple of examples on the Adapter class:

1. MouseAdapter

Take a look at the class description. See also the tutorial on writing a mouse listener making use of MouseAdapter.

2. WindowAdapter

Take a look at the class description. See also the tutorial on writing a window listener, and how WindowAdapter fits in.

Adapter classes can be used to ease the implementation of interfaces in general (i.e., not only for listener implementation.)

There is a another called the Adapter Design Pattern. It is one of the GoF (Gang of Four) design patterns, and it is applied to enable dissimilar interfaces to work together. See Adapter pattern - Wikipedia, the free encyclopedia.
