学生管理系统（课程设计附带源码）
1. 问题要求及任务描述
1.1. 题目要求
学生管理系统
对学生信息管理系统，要求完成以下基本任务：
- 改写程序为良好程序风格（文档注释，函数注释，语句注释）。
- 将功能补充完全（基于文件处理，完成刷新和保存功能）。
- 将学生信息改为更好的数据组织，而非离散形式（结构体）
1.2. 主要任务
- 能够对学生的有关资料进行输入，查询，修改，删除。
- 能够为学校提供强大的查询功能，以便管理人员了解和掌握学生的具体 情况。
- 能够对数据库和登陆记录进行清理。
- 可以对用户进行修改密码，新增用户。
2.1. 采用解决问题的方法
首先就是学生信息的录入，要求将信息用文件保存，在这里我设计了一个类Student，有9个成员变量分别是
private int id; //学生编号
private String stuName;//学生姓名
private String stuXue;//学生学院
private String stuIdcarde;//学生学号
private String stuSex;//学生性别
private String stuAge;//学生年龄
private String stuAddress;//学生地址
private String stuPhone;//学生联系方式
private String stuTypeid;//学生班级，
除了id（自加，且唯一）是int类型，其他都是string类型，同时里面还有成员函数，
public int add(Connection con,Student student)throws Exception
public int update(Connection con,Student student)throws Exception
分别向程序里面读数据和写入数据，还有负责添一条数据的成员函数add（）可以添加一条信息，同时我将学生的信息有list容器存放。。
然后我是先做查询的，因为这有做了查询才能删除和修改，查询我也是按照学号查询，查询出来的信息在右边的实例编辑框中展示出来，然后对编辑框进行一些属性的调整，例如可下滑（当文本长度过长时可下滑）、可换行、只读，然后学号和姓名等都设置可输入编辑框，只有当对应查询方式有效时才能进行查询，，若有效会进行查询将对应结果输出，无输出结果会有对应的提示框弹出。然后我做了删除和修改，这是用按照学号查询的方法来查询的。
