Although the meaning can differ by platform, in the context of Java Swing an ActionListener implements a function actionPerformed(ActionEvent) that will do something when a user does some action, according to this Oracle tutorial. An ActionListener is a subinterface of EventListener. EventListener contains several subinterfaces, for example MouseWheelListener, which does something when the user moves the mouse wheel.

The ActionListener interface is utilized for treating action events. For illustration, it's used for button clicks by a JButton, for checking by JCheckbox and unchecking, by a JMenuItem when an option is picked and a lot of other graphical components.

It's a uncomplicated interface with only one technique:

 public interface ActionListener extends EventListener

 {
    public void actionPerformed(ActionEvent e);
 }

An event listener is used to practice events. For instance, a graphical component similar to a JButton or JTextField is acknowledged as event sources.

This indicates they can generate events - when a user relates to on the JButton or types text into the JTextField. The event listener’s job is to catch those events and do incredible with them.

The interface ActionListener is a subinterface of EventListener. In practice, it is probably better to implement the most specific interface you can, such as ActionListener or WindowListener.
