## 20.17 java.awt.event.KeyAdapter (JDK 1.1)

###

This class is a trivial implementation of `KeyListener`; 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 `KeyAdapter` than it is to implement `KeyListener` from scratch.

    public abstract class KeyAdapter extends Object implements KeyListener {
        // Default Constructor: public KeyAdapter()
        // Public Instance Methods
                public void keyPressed(KeyEvent e);  // From KeyListener
                public void keyReleased(KeyEvent e);  // From KeyListener
                public void keyTyped(KeyEvent e);  // From KeyListener
    }
