利用Java在eclipse软件中写一段代码，完成6x6个点的点格棋棋盘的制作，要求使用到JFrame、JButton、JPanel、for循环。以下是详细要求： 一、页面设计 左边是棋盘，右边是按钮 二、棋盘制作： 1.按钮：先手、后手、悔棋、计时键、棋谱。 按钮要能点击，点击即实现相应功能 2．下棋：只需要实现下棋前两步 （1）选择ai先手 利用随机函数让ai随机落子 （2）自己是先手 ，ai下第二步时利用随机函数让ai随机落子 （3）下棋的位置要符合点格棋下棋规则：棋子只能横向竖向下，只能走一格；计算机系大一新生的程序设计作业，尽量写的简单些，注释详细些

以下是Java代码实现：

上述代码实现了一个简单的点格棋游戏，包括棋盘的制作、下棋规则的实现、悔棋、计时、棋谱等功能。其中，AI使用了简单的贪心算法，评估每个空位下棋后的得分，选择得分最高的位置下棋。在AI先手时，第一步为随机落子，第二步为选择得分最高的位置下棋。
