Question

Quizplus · Accepted Answer

To receive notification of KeyEvents, a class must implement the KeyListener interface. Therefore, the best choice is B, KeyListener. Option A, KeyHandler, is not a valid class or interface. Option C, EventListener, is a general interface that other specific event listener interfaces, such as KeyListener, extend. Option D, KeyEvent, is a class that represents a key press or release event, but it is not an interface that can be implemented.
