public abstract class MouseAdapter
extends Object
implements MouseListener

An abstract adapter class for receiving mouse events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Mouse events let you track when a mouse is pressed, released, clicked, when it enters a component, and when it exits. (To track mouse moves and mouse drags, use the MouseMotionAdapter.)

Extend this class to create a MouseEvent listener and override the methods for the events of interest. (If you implement the MouseListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

Create a listener object using the extended class and then register it with a component using the component's addMouseListener method. When a mouse button is pressed, released, or clicked (pressed and released), or when the mouse cursor enters or exits the component, the relevant method in the listener object is invoked and the MouseEvent is passed to it.
