Multiple listeners per event

[Java Tip]

One event can have multiple listeners as shown in the example below:

public class BeepFiveApplet extends Applet  {
  
   public void init () {
   
     // Construct the button
     Button beep = new Button("Beep");

     // add the button to the layout
     this.add(beep);

     // specify that action events sent by this
     // button should be handled by a new BeepAction object
     beep.addActionListener(new BeepAction());
     beep.addActionListener(new BeepAction());
     beep.addActionListener(new BeepAction());
     beep.addActionListener(new BeepAction());
     beep.addActionListener(new BeepAction());
  
   }
}

Hello.

Can you please explain why one would need multiple ActionListeners on the same component. For me, it would make more sense if you add different types of event listeners.

Thanks for the Tip! ;)
