前言
学习是一个漫长而又痛苦的过程，但学习的收获是令人欣喜的，为了让学习成果有质量，又有痕迹，特意写此博客，由于本人非计算机专业，但对计算机兴趣万分.如有错误，望各位读者斧正。(本程序的所用的数据，名字是源于网上，其余都是随机生成，如有侵权，请私信我)

项目流程
登录流程图
学生管理系统由四个模块构成，每个模块都有不同的方法，下面的流程图列出了主要的方法。
模块分讲
首先Login登录，用户密码正确之后，进入主页面GuiMain，StuPassword负责修改密码，StuWindow负责添加、修改等功能，以上就是各个模块负责的功能，下面来分开讲解一下。以下每一个模块都能单独运行。
Login
Login登录模块，会从文件中读取数据，用户输入密码登录，会和读取的密码进行校验，正确会进入主界面，错误会提醒。考虑到首次运行会没有数据，所以第一次运行会随机生成一些数据，以便主界面效果展示。
