public interface ItemListener extends EventListener
The listener interface for receiving item events. The class that is interested in processing an item event implements this interface. The object created with that class is then registered with a component using the component's `addItemListener` method. When an item-selection event occurs, the listener object's `itemStateChanged` method is invoked.
