马士兵的坦克大战，以前做过，今天又找出来看了看

总结：

事件处理机制一般用Adapter形式

常用Monitor继承Adapter

 

线程每秒都在不停地刷新Runnable接口熟练

 

懒汉式：把main函数写在class里面

 

枚举

enum  color {red，blue，green，write};

color c=red;

 

public static final int定义一些常量，不能实例化，一变全变，不能改变

代码重构
将以后可能需要多处改变的量定义为常量

 

new 一个tank

tank的draw 从paint里面抽取，KeyPressed从KeyMonitor里面抽取

 

把tankClient的引用当做参数传入tank，missile里面去，当一个大管家

 

ArrayList来装载炮弹misssile，定义生命值，死亡就remove

以及超级for循环的使用

 

定义友好量，判断是自己人还是敌人   

 

爆炸这种动画用一个数组来存储，改变脚标，改变值

 

superFire很简单

booldBar也很简单

 

怎么生成压缩格式的jar忘了！！！

怎么生成文档也忘了！！！
