**运行项目效果，进行分析。**

*  敌人分三种:小敌机、大敌机、小蜜蜂  
    英雄机可以发射子弹，子弹可以打敌人
 *  子弹打掉小敌机----------玩家得1分  
    子弹打掉大敌机----------玩家得3分  
    子弹打掉小蜜蜂----------英雄机得奖励(1命、40火力值)
 *  英雄机的火力值为0，则为单倍火力(一发子弹)  
    英雄机的火力值大于0，则为双倍火力(两发子弹)  
    发射一次双倍火力，则火力值减2
 *  敌人可以和英雄机撞，撞上之后:  
    英雄机减命，同时，英雄机清空火力值  
    当英雄机的命数为0时，则游戏结束

设计对象类:  
1.找对象:英雄机、子弹、小敌机、大敌机、小蜜蜂、天空  
2.抽类:Hero、Bullet、Airplane、BigAirplane、Bee、Sky  
3.设计类中的成员变量和方法:  
4.创建对象并测试:

**创建包：**  
cn.tedu.shoot  
**创建类：**  
Hero  
Airplane  
BigAirplane  
Bullet  
Bee  
Sky  
World
