## 20.22 java.awt.event.MouseListener (JDK 1.1)

###

This interface defines the methods that an object must implement to "listen" for mouse events on AWT components. When a `MouseEvent` occurs, an AWT component notifies its registered `MouseListener` objects (or `MouseMotionListener` objects if the event involves mouse motion) by invoking one of their methods.

An easy way to implement this interface is by subclassing the `MouseAdapter` class.

    public abstract interface MouseListener extends EventListener {
        // Public Instance Methods
                public abstract void mouseClicked(MouseEvent e);
                public abstract void mouseEntered(MouseEvent e);
                public abstract void mouseExited(MouseEvent e);
                public abstract void mousePressed(MouseEvent e);
                public abstract void mouseReleased(MouseEvent e);
    }

### Implemented By:

`AWTEventMulticaster, MouseAdapter`

### Passed To:

`AWTEventMulticaster.add(), AWTEventMulticaster.remove(), Component.addMouseListener(), Component.removeMouseListener()`

### Returned By:

`AWTEventMulticaster.add(), AWTEventMulticaster.remove()`
