TIC TAC TOE 消去版
最近在翻学长留下的资料，发现了一个很奇怪的TIC TAC TOE的实现：
- 两个玩家，一个打叉(X)，一个打圈(O)， 轮流在3乘3的格上打自己的符号，最先以横、直、斜连成一线则为胜。下图是一个X方取胜的例子。
- 因为旧玩法如果下法无误，将得和局，所以出现变化，新玩法是在下完第七子时(先方第四子)，最初的第一子要消失，第八子下完第二子消失，以此类推，保持盘上只有六子，下子后必须先处理消失之子，方可判断是否连成一条线。
不知道是不是自己比较笨，第二种是现实想了好久好久(⊙﹏⊙)b，但总算还是想出来了：主要是用ArrayList + Comparable的借口实现排序（感觉说起来很简单的样子，不知道为什么搞了两天多）。。。
现在的问题就是：
- 代码繁杂：不少地方用了类似的代码段，但其中有些细微的差别，貌似不能用函数来笼统解决这个问题，让我很无奈；
记录步数有限：由于用了一个全局变量来记录总步数并将步数分配到每个按键上，导致最终的游戏总步数有限（虽然我想2^31-1步没人能玩下来），姑且算一个不足。
希望各位大大给出建议~
代码如下：

PS：那个注释部分是第一种实现，没有把它融入整个游戏中；
PPS：没有注释真是不好意思；
PPPS：INTELLJ真是意外好用，貌似eclipse不能在ActionListener里头设断点，但IntellJ可以，而且Debug时顺手多了。
