      public interface MouseListener
      extends EventListener

  The listener interface for receiving "interesting" mouse events (press, release, click, enter, and exit) on a component. (To track mouse moves and mouse drags, use the `MouseMotionListener`.)

  The class that is interested in processing a mouse event either implements this interface (and all the methods it contains) or extends the abstract `MouseAdapter` class (overriding only the methods of interest).

  The listener object created from that class is then registered with a component using the component's `addMouseListener` method. A mouse event is generated when the mouse is pressed, released clicked (pressed and released). A mouse event is also generated when the mouse cursor enters or leaves a component. When a mouse event occurs, the relevant method in the listener object is invoked, and the `MouseEvent` is passed to it.
