Question: 1 / 510

What does the addActionListener method expect?

A class that implements ActionListener

The addActionListner method expects a class that implements ActionListener because it specifies which object should receive ActionEvent notifications when the event occurs. Option B is incorrect because the method does not require an Event object. Option C is incorrect because while a button object can implement ActionListener, it must be specified as an argument when registering the Listener. Finally, option D is incorrect because String is not a valid parameter type for addActionListener. So overall, the correct answer is A.
