[size=large] [color=darkred]五子棋的开发[/color] [/size]

一.五子棋开发的难点
1.算法
具体是五子棋排放，判断输赢的方法。
2.代码结构复杂度提高

二.技术点:
1.JFrame, Graphics, 按钮
2.事件
3.重绘
4.算法

其实学习五子棋是为了复习巩固以前学习的一些内容。掌握JFrame的基本操作，过去画板，添加按钮，在按钮这个事件上添加监听器。掌握继承的方法。实现重绘，能够展现一个简单的五子棋对战的小游戏。最后能够实现人机对战。编写方法，用算法实现这个。掌握五子棋的具体算法。

三.过程分解
1.在窗体的画板上，画上直线与横线形成一棋盘格子(建立坐标)
应用坐标的关系，画出五子棋的线条布局，实现一个五子棋的基本框架。

2.在窗体的画板上绘制棋子(事件处理)
给事件添加接口，实现接口，能够绘制五子棋，黑白相间的。

3.人人对战完成胜负判断(下一颗白子接着一颗黑子)
写出算法，能够判断输赢，实现自己和自己下棋。

4.人机对战(机器人下棋策略，也就是五子算法)
