前言
小时候大家都玩过坦克大战吧，熟悉的旋律和丰富的关卡陪伴了我们一整个寒暑假，还记得传说中的经典坦克大战 吗？那些怀旧的记忆，伴随着我们一起走过来的经典坦克大战，刚开始那战战兢兢，屡屡被敌人坦克击毁的情景历历在目。现在好了，再也不用担心敌人坦克了，可 以横冲直撞，横扫敌人坦克了。快哉！！！
《坦克大战》游戏以坦克战斗为主题，用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。
主要需求
可以生成不同的地图，消灭地图上的所有坦克为胜利；可以设置关卡地图，不断增加难度。
主要设计
1、要有难度关卡：第一关，第二关，第三关，第四关，第五关；第一关地图最简单，第五关地图最难；
2、坦克要有血条，打多次才会死
3、地图要我有我方坦克四辆（相当于4条命）和多辆敌方坦克
4、我方坦克的炮弹数量是固定的，设置为500
5、地图右边显示基本信息
6、地图上要在砖块，铁块，河流

总结
通过此次的《坦克大战》游戏实现，让我对swing的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。
java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
