java——博弈算法实现井字棋游戏
通过java语⾔开发了⼀个简单的井字棋游戏。主要有6个类，其中有⼀个是主类（Main.java），⼀个是抽象类（PiecesMove.java）组成。
下⾯对各个类简单介绍⼀下：
TicTicToe.java:
主要负责创建棋盘，管理棋盘。
TicTicToeUI.java:
主要由判断谁是先⼿的对话框、对战界⾯和提⽰谁输谁赢三个对话框组成，负责管理⽤户交互。
PiecesMove.java:
⾥⾯有2个⽅法，move(TicTacToe tict)是抽象⽅法由⼦类实现，isWinning(int[][] cur)判断是否游戏结束。
Computer.java:
负责计算机的落⼦位置计算，核⼼算法为博弈算法。
Player.java:
负责获取⼈落⼦的位置。
Main.java:
负责创建以上类的实例，控制谁先⾛⼦，游戏结束是否继续等逻辑处理。
下⾯贴出源代码：
