下面，启动登录窗口，成功登录后，可以在主界面里通过菜单系统调用各个功能模块。
运行结果，如下：
经过6天的实训，之前都没有打过这么多的代码，这次前面那些还是跟着老师打的，有照的老师打的，实在太多了，我承认其中有copy老师的。完成了happy，在这写这个学生管理系统中，我学习到了要，做什么都要有逻辑思维，一步一步来，在刚开始的时候跟着老师打，这样也不觉得代码很多，然后老师喊我们看着他的笔记自已尝试着写，我觉的代码好多啊，打完了过后，发现很多方法其实都是差不多的。我也在本次实训中收获了不少，巩固了一下本学期的基础知识。在打代码的过程中，我也有许多的不会，在打代码的过程中，很多的不会，都是在老师帮助下修改成功的。
本次实训代码已写完
