Examples of Java events

Words don't say much, on the code:

Package Test;import Java.util.eventlistener;import Java.util.eventobject;import java.util.list;import    Java.util.vector;class Eventclassone extends eventobject{public eventclassone (Object source) {super (source);    }}class eventsource{public String name;    Public EventSource (String name) {this.name=name;        }//Store the event listener's basket vector listeners=new vector ();//Add the event listener to the basket public void AddEventListener (EventListener e) {    Listeners.add (e); }//action to trigger event public void say (String s) {for (int i = 0; I <listeners.size (); i++) {((M        Yeventlistener) Listeners.elementat (i)). Action (new Eventclassone (this)); }}}class MyEventListener implements EventListener {public void action (EventObject eventobject) {if (EVENTOBJ            Ect.getsource () instanceof EventSource) {String name = ((EventSource) Eventobject.getsource ()). Name;        System.out.println (name+ ", shout what shout, noisy to others have sex"); }}}pUblic class Eventtest {public static void main (string[] args) {EventSource Xiao Feng =new EventSource ("Xiao Feng");        EventSource giant pillar =new EventSource ("giant Pillar");        MyEventListener listener1=new MyEventListener ();        MyEventListener listener2=new MyEventListener ();        Xiao Feng. AddEventListener (Listener1);        Xiao Feng. AddEventListener (Listener2);        Giant pillar. AddEventListener (Listener1);        Xiao Feng Say ("Want a Macho Man");    Giant pillar. Say ("Want a Beautiful Woman"); }}
