用Java编写简单的五子棋——人机对战！
前言
2022-02-04，农历正月初四
首先在这祝大家新年快乐。
距离上两个版本的更新已经过去了很久，因为年前工作非常忙，经常熬到凌晨，导致我看大家私信和回复的时间有限，但我会用上厕所摸鱼的宝贵时间仔细查看并回应大家的互动。
那天我看到有同学问我人机对战如何实现，说实话这玩意三言两语很难解释清楚，不如直接写一个让大家看来的直接，所以我没有回答他的问题，而是找时间把这个功能做出来，争取让所有想问这个问题的同学找到答案。
终于来到了年假，招待完亲戚朋友后，脑子里的第一件事就是将这个功能做完展示给大家，博主不才，花了一下午时间干出来，就当我给大家的新年礼物了。

结束语
原来的MyJFrame类里的代码没有改变，依然是人人对战；MyJFrame_AI类是在MyJFrame类的基础上修改为人机对战。
博主测试的比较匆忙，只玩了一遍，没有发现BUG，大家在游玩过程中如果发现BUG，欢迎私信。
往期文章可以翻阅我的主页，我一直坚持“分享知识”的原则，免费透明的将全部代码公开展示，如果帮到了你，请顺手点个赞吧(#.#)。

不放心，又测试了一晚上BUG，果然有问题：
1.修复了悔棋时只能撤回电脑棋子的BUG
2.修复了在特定情况下，电脑方或玩家方胜利没有反应的BUG
3.优化了电脑的权值计算，但还是不太聪明的样子
