一个星期都是Java课，一直敲代码，感觉真的是好累好累啊。但是生活正在苦不一样要继续吗？今天接着码代码吧。说实话打了这么多东西，是真的学到了很多的东西。比如写GUI一般的格式有什么，大概改怎么打还是学到了一些。但是让自己独立写的话还是很难独立完成。毕竟懂的东西要更多一些。

今天接着昨天的打吧，开始写添加学生窗口AddStudentFrame

写完了这个GUI以后，我突然觉得里面的内容至少有一般以上是相同或者相类似的，其实自己可以不用那么累，可以复制粘贴，但是又想到复制粘贴对自己有什么用呢，自己一样学不到然后东西。于是又接着一个一个的开始码代码。

这三个删除类其实差不多，只是有一些地方有一些不一样而已。写完了这三个删除类的界面，接着就写查询窗口

Java的学生信息管理系统 java学生信息管理系统总结_ide_03

查询有四种方法，按学号查询，按姓名查询，按班级查询，按系部查询。

四种查询方法都是差不多的，代码也就差不多。

其他查询也是和这个相类似的所有就不写在博客上面了。看了一下老师的代码发现好像剩下的不是很多了，而且自己今天也差不多接近下课了，就觉得不写了。正好晚上也还有事情就歇一下明天写吧。
