The question is as follows: The following is a listing of the interface class actionListener from the Java API:
package java.awt.events; import java.util.EventListener; public interface ActionListener extends EventListener { public void actionPerformed(ActionEvent e); }
Explain the role of this interface in GUI programs written in Java.
I believe the action listener interface is there for receiving action events. The class that is interested in processing an action event implements this interface, and the object created with that class is registered with a component, using the component's addActionListener method. When the action even occurs, that object actionPerformed method is invoked.
What more could be said about this?
