A question about firing event, please help

Question

I would like to know how to fire an event in the following situation:
public class FireAnEvent
         public static void main()
               char c=(char)System.in.read())s;
               String source="I'm the source";
               if(c!="a")
                      fireActionEvent(new ActionEvent(source,1,null);
}the above code won't work obviously, but what should i do to make it work, or is it possible to fire in this situation?
thanks in advance;

My personal favourite way to quickly fire custom events is through using enums in the XXXEvent class. That way checking which event was called is easy, and it's also typesafe.
fireXXXEvent(XXXEvent.ID.MY_ID, "...");
  private List<XXXListener> listeners = new LinkedList<XXXListener>();
  private synchronized void fireXXXEvent(XXXEvent.ID eventID, String args) {
    XXXEvent event = new XXXEvent(this, eventID);
    event.setupOtherStuff(args);
    for (XXXListener l : listeners) {
      switch (eventID) {
        case MY_ID:
          l.xxxAction(event);
          break;
        case MY_OTHER_ID:
          l.xxxOtherAction(event);
          break;
        default:
          break;
  public synchronized void addXXXListener(XXXListener l) { listeners.add(l); }
  public synchronized void removeXXXListener(XXXListener l) { listeners.remove(l); }
