I know adapter pattern is like real adapter,:

1-What does this mean?

In the Adapter Design Pattern, a class converts the interface of one class to be what another class expects.

Answer to question 1 is as follows,

java.awt.event.WindowListener // Interface
java.awt.event.WindowAdapter // Adapter. This class implements the WindowListener interface.

Now if you implement the WindowListener interface, you need to implement all the methods declared in the WindowListener interface. However, if you extend the WindowAdapter class you may over-ride only the required methods.
