What is ActionListener used for in Swing?

Listening for variable changes
Handling action events
Tracking mouse movements
Monitoring window size changes

The correct answer is: Handling action events

The ActionListener interface in Swing is used for handling action events, such as button clicks or menu selections. This allows the application to respond to user actions and trigger specific actions or behaviors. Option A, listening for variable changes, is not specific to Swing and can be handled by other means. Option C, tracking mouse movements, is handled by the MouseMotionListener interface. Option D, monitoring window size changes, is handled by the ComponentListener interface.
