PS：这学期期末成绩差不多出完了，接下来会陆续把这学期课程中的代码陆续扔到这里来以便后人****，同时自己也留个纪念。
本学期选了java选修，期末大作业面向GitHub编程写了个中国跳棋。代码中还有写小bug，不过懒得调了...
update:github
1.游戏介绍
中国跳棋，简称跳棋，是一种可以让二至六人一起玩的棋，棋盘为六角星形状，棋子一般分为六种颜色，每种颜色有10或15枚棋子（或弹珠），每一位玩家占一个角，执一种颜色的棋子，如果玩的人数较，也能每人执两种颜色的棋子玩。
游戏规则如下：
先将一种颜色的棋子按规则全部放在一个角上，各人循顺时针或逆时针方向轮流走子，每次只能动一枚棋子，全部棋子先到达对角那一边的为赢家。棋子有两种走法：
1)一枚棋子移动到相邻六格其中一格。
2)“搭桥”:自己的棋子(A)同一条直线上还有一枚棋子(B),不限属于哪一方,大家之间没有任何棋子阻隔。如果B的另一方也没有棋子阻隔，A就可以跳到B的相反方向，而且和两枚棋子原来的距离一样。跳跃可以一直进行下去，直到没有前进的路径为止。如果有循环情况，可在任意一处停下。
2.项目介绍1）本跳棋project支持两人、四人、六人跳棋对战
2）具有计时功能，可显示当前时间，同时也可判断当前玩家是否超时
3）游戏可暂停
4）可保存当前局面，从本地打开已有文件（文件I/O）
