java-programmer, Custom event Hello All,

How can I write a custom event?
I want to create a custom event object and fire it at a particular point in
program.

Thanks in advance!

Regards
Suma

public class MyEvent {}

public interface MyListener {
void eventFired(MyEvent evt);
}

public class AnObservable {
private List<MyListener> listeners;

public void fire() {
for (MyListener ml : listeners) ml.fire(new MyEvent());
}

public void addListener(MyListener ml) {
listener.add(ml);
}
}

public class AnObserver {
private MyListener myListener = new MyListener() {
public void eventFired(MyEvent evt) {
// react to event being fired
}
};
}
