## 20.5 java.awt.event.ComponentAdapter (JDK 1.1)

###

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

    public abstract class ComponentAdapter extends Object implements ComponentListener {
        // Default Constructor: public ComponentAdapter()
        // Public Instance Methods
                public void componentHidden(ComponentEvent e);  // From ComponentListener
                public void componentMoved(ComponentEvent e);  // From ComponentListener
                public void componentResized(ComponentEvent e);  // From ComponentListener
                public void componentShown(ComponentEvent e);  // From ComponentListener
    }
