引言：
象棋的代码实现有点复杂，尤其是计算机的AI算法，在网上找了很多资料，费了好半天劲才弄明白其实现的原理，真的挺开阔思路的，很有意思！
思路：
1、创建主窗口，加载菜单及游戏面板。
2、在游戏面板中初始化各种参数，并建立各种功能组件。
3、利用标签图像做棋子，并结合paint()函数。
4、利用mouseMoved()鼠标移动函数设置落子指示器的位置。
5、利用mouseClicked()鼠标单击函数来判断是否可以下棋，由哪方来下，判断是否平局或胜利。如果是人机对战要计算电脑要下棋的最佳位置。
6、游戏结束，收尾，准备下一局。
代码：
图片位置与包位置平齐，因为我装载图片时是从类路径开始取，取绝对路径是不认可的。
本游戏用的是JDK1.8，编码UTF-8；
共有4个类，Chess.java是游戏入口类。GameFrame.java是主窗口类。GamePanel.java是游戏面板类。GameLogic.java是游戏逻辑类。先一口气把所有的代码贴上来再说。
