【Little_things】控制台五子棋（java）

   一共4个类：

  1，Board类 主要方法：

      1.1void initBoard（），初始化棋盘

      1.2void displayBoard（），输出棋盘

      1.3String[][] getBoard（），获取棋盘

2.Chessman类，是枚举类

3.Gogame类，主要方法

      3.1String input（），输入

      3.2 boolean isValid（String input()），判断输入是否合法

      3.3boolean isReplay（String Chessman），Chessman是黑子或白子，判断是否重玩

      3.4boolean isWon（int x,int y,String ico）,x，y是落子的坐标，ico是棋子类型，判断是否赢了

      3.5int[] computerDo(int x,int y,int oldx,int oldy),x,y为当前落子点oldx，oldy为前一落子点，计算机生成落子点

      3.6void start（）  启动游戏

4.Main类
