课程设计要做一个游戏,由于对C++不是很熟悉,老师也准许使用java 或者其他的语言,在.net我学过事件,一种委托回调,但是在java 我不是很了解,应该原理都相同吧!
游戏大致是这样的,现在这在写成功判断!于是我自己加了一个事件\
package com.zhaojun.base;
import org.w3c.dom.events.Event;
import java.util.*;

1.首先要使用事件,自己就必须写一个接口 继承EventListener 然后里面写一个需要实现的接口方法
/**
* 成功接口
*/
public interface WinEvent extends EventListener {
public void DoEvent();
}
private Collection winlistener;
/**
* 添加成功事件
*
* @param listener
*/
public void addWinListener(WinEvent listener) {
if (winlistener == null) {
winlistener = new HashSet();
}
this.winlistener.add(listener);
}
private void notifyDoEvent() {
Iterator iter = winlistener.iterator();
while (iter.hasNext()) {
WinEvent listener = (WinEvent) iter.next();
listener.DoEvent();
}
}
2.实现基本的添加事件和通知就可以了;;;接下来就是使用了
哈哈,成功了!
