一个比较早的Java打斗游戏代码，以前J2me盛行时候的一个游戏源码，不过里面的java代码和现在的android有共同之处，有兴趣的研究下。代码中的游戏服务器类，负责控制游戏规则，为客户端提供游戏控制信息；另还有音频文件播放类、游戏绘制类、游戏玩家显示类、游戏客户端MIDlet类等完成各自对应功能。

可折叠展开的Flash图片导航菜单。3屏x4flash焦点图代码，点击左右两端的书签，展开不同的图片，可用于显示网站的精彩推荐内容或显示一些比较重要的更新。本代码还有一个特点就是把XML配置文件省略。

这个程序允许用户显示一个动画的闪屏，当程序执行且花费更长的时间来启动。

U盘控制芯片CH331,CH331 是一个小容量U 盘的控制芯片，只要外加一个串行存储器芯片，就可以实现2KB 到512KB 的小容量U 盘。-U disk controller IC CH331, CH331 is a small-capacity USB control chip, As long as plus a serial memory chips, we would achieve 2 KB to 512 KB of small U disk capacity.
