THE THIRTY-FIVETH DAY

    今天星期四，参加培训的第三十五天，还是和昨天一样，没有什么改变，忘记早上看的什么，好像是什么ifelse什么的，然后到教室开始看mysql没有别的什么。

    mysql的什么呢，对数据库的操作，什么创建database,drop,alert,对表的操作什么的，alter,modify,create,describe,show,还有数据库的运算符什么的，别的好像没有什么了，好像是没有什么状态，自己的程序做了一点点，没有什么进度，也还好吧，今天分个，服务器和客户端，然后弄个对话聊天就结束吧，没有什么好写的了，无从下手，我记的有人写过这个视频，所以去看下，然后模仿弥补一下自己的不足，嗯，就是这样。好的。

    我想起今天为什么没有效率了，数据库有问题，什么密码不对什么的错误，原因呢就是在用 properties文件的时候，好像是最后，加了空格什么的，导致密码错了，无所谓了，就是一上午罢了，也没有别的什么。

    还有什么好说的呢，也没有别的什么了，就随便贴个代码吧。

简陋的qq主界面代码：
