* 这个五子棋游戏是2003年3月份学习j2me编程时写的，因为程序比较简单，
* 代码结构不太好，但是j2me编程过程中的一些典型case都有涉及到，像
* 界面生成，按键控制，资源文件的读取，小内存编程等等。
*
* 这个游戏在编写时感觉有两个难点，一是界面部分，一是AI部分。
*
* 界面部分就是靠画出来了，很烦琐，但是没有好办法。
* 最开始的时候我是把棋子作为一个单独的class来做，
* 但是后来经过对比发现还是直接画出来比较省内存。
*
*
* AI属于常规编程，这里采用的是最笨的权值判断的方式。
* 如果有好的算法可以将其替换。
*
* 本代码建议仅供学习j2me编程使用。
*
* 2005.2.23
* 今天是我的生日，公布这个代码就当庆祝一下自己的生日吧
* 当时写这个程序的时候，感谢wda中文网(http://www.wda.com.cn)
* 中国java手机网(http://www.cnjm.net)
* 感谢昨天晚上第一个收到GT的短信祝福，还有别的很多朋友的短信，让我高兴了今天一天
* 也谢谢YWSY(http://bbs.ywsy.net)上的各位好朋友。
