e643. 以匿名类处理事件

If an event handler is specific to a component (that is, not shared by other components), there is no need to declare a class to handle the event. The event handler can be implemented using an anonymous inner class. This example demonstrates an anonymous inner class to handle key events for a component.

    
component.addKeyListener(new KeyAdapter() {
        public void keyPressed(KeyEvent evt) {
        }
    });
