## 18.8 java.awt.Canvas (JDK 1.0)

###

This class is a `Component` that does no default drawing or event handling on its own. You can subclass it to display any kind of drawing or image, and to handle any kind of user input event. `Canvas` inherits the event handling methods of its superclass. In Java 1.1, you can also subclass `Component` directly to create a "lightweight component," instead of having to subclass `Canvas`.

    public class Canvas extends Component {
        // Public Constructor
            1.1 public Canvas();
        // Public Instance Methods
                public void addNotify();  // Overrides Component
                public void paint(Graphics g);  // Overrides Component
    }
