What is required to handle a button press event in Swing?

  1. Implement EventListener

  2. Implement ActionListener

  3. Override actionPerformed()

  4. Both B and C

The correct answer is: Both B and C

In order to handle a button press event in Swing, you need to implement both EventListener and ActionListener. This is because EventListeners define a set of methods that respond to different events, and the ActionListener interface is specifically designed for handling button press events. In addition, to handle the button press event, you must override the actionPerformed() method, so option C is also incorrect. Implementing just one of these options will not fully handle the button press event.
