## 20.20 java.awt.event.MouseAdapter (JDK 1.1)

###

This class is a trivial implementation of `MouseListener`; it provides empty bodies for each of the methods of that interface. When you are not interested in all of these methods, it is often easier to subclass `MouseAdapter` than it is to implement `MouseListener` from scratch.

    public abstract class MouseAdapter extends Object implements MouseListener {
        // Default Constructor: public MouseAdapter()
        // Public Instance Methods
                public void mouseClicked(MouseEvent e);  // From MouseListener
                public void mouseEntered(MouseEvent e);  // From MouseListener
                public void mouseExited(MouseEvent e);  // From MouseListener
                public void mousePressed(MouseEvent e);  // From MouseListener
                public void mouseReleased(MouseEvent e);  // From MouseListener
    }
