(最新修改——显示节日)----Java写出来的日历（有显示农历）

  前言：我总是喜欢看日历，看多了突然萌发出来自己想做个日历出来的想法。本来自己是个程序员（java），目前上班空闲时间也算多；于是从网络上看了看有关怎样用java来实现日历的相关示例及文章，自己就开始动手操作了！不过现在做出来还是有点漏洞：就是程序初始化运行之后，系统当前日期的颜色突出显示问题；当我更换月份、或者是年份后再回到当前的时间，突出显示当前(今天的)时间的颜色会随鼠标的移动而消失；这个让我不解，试了好多中方式都没弄好！希望javaeye的高手们看了后，能帮我解决这个问题……好了废话不多说，马上把源代码贴出。。。(注：Java日历.rar附件是用exe4j打包出来的exe可执行文件，如本机安装了JDK或是有不是安装版JDK的环境变量；都可以直接双击运行查看效果)

 农历显示的类文件是从网上找到的，在这里感谢那位提供者！附件MainCal.rar中的Lunar.java就是提供显示农历的java类；解压MainCal.rar在Myeclipse中直接运行MainDate.java类，也可以查看效果…

   注：根据网友回馈的bug，【农历显示错误】我做了一下修改；上面主程序日历代码也有所变更，想查看更改后的效果：请下载“附件更改”的附件，两个附件是对应之前的；源代码就不贴出来了，请自己看附件吧……
