一、实践目的：

1.鼠标点击、拖动等事件的应用与区别

2.棋谱文件的保存与读取

3.完善象棋的规则。

二、实践内容：

中国象棋历史悠久，吸引了无数的人研究，现对中国象棋的对战和实现棋谱的制作做如下的设计和说明，供大家参考学习。

1、机机对弈，红方先手。在符合规则的情况下拖动棋子到目的地，松鼠标落子。

人人对弈图

2、制作棋谱，选择制作棋谱菜单后，对弈开始，并记录了下棋过程。

选择“制作棋谱”菜单

棋谱制作完毕红方胜出

一方胜出后弹出胜利消息对话框。点击确定后，选择“保存棋谱”菜单，弹出保存文件对话框。

保存棋谱对话框

3.演示棋谱，选择演示棋谱菜单后，弹出打开对话框，选择保存好的棋谱，开始演示。

演示棋谱对话框

演示棋谱过程(自动和手动两种)

四、总结与要求

1.理解8个文件，没有太复杂的代码。

2.理解鼠标的MouseListener,MouseMotionListener两个接口的区别，五子棋的实现不需要MouseMotionListener。

3.使用LinkedList记录棋谱的方法。
