坦克大戰【3】
筆記目錄：(https://www.cnblogs.com/wenjie2000/p/16378441.html)
坦克大戰0.6版
√增加功能
-
防止敵人坦克重疊運動
-
記錄玩家的成績（累積擊毀敵方坦克數）,存盤退出【io流】
-
記錄當時的敵人坦克坐標與方向,存盤退出【io流】
-
玩游戲時，可以選擇是開新游戲還是繼續上局游戲

坦克大戰0.7版
增加功能
-
游戲開始時，播放經典的坦克大戰音樂(AePlayWave.java此類可直接使用成品，不自己寫)(需要準備wav格式音樂檔案)
-
修正下檔案存盤位置（保存到src目錄下）
-
處理檔案相關例外=》提升程式健壯性(處理讀取游戲資訊檔案不存在出現的例外)
