坦克大战【3】
笔记目录：(https://www.cnblogs.com/wenjie2000/p/16378441.html)
坦克大战0.6版
√增加功能
-
防止敌人坦克重叠运动
-
记录玩家的成绩（累积击毁敌方坦克数）,存盘退出【io流】
-
记录当时的敌人坦克坐标与方向,存盘退出【io流】
-
玩游戏时，可以选择是开新游戏还是继续上局游戏

坦克大战0.7版
增加功能
-
游戏开始时，播放经典的坦克大战音乐(AePlayWave.java此类可直接使用成品，不自己写)(需要准备wav格式音乐文件)
-
修正下文件存储位置（保存到src目录下）
-
处理文件相关异常=》提升程序健壮性(处理读取游戏信息文件不存在出现的异常)
