篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了java的学生成绩管理系统（swing环境）相关的知识，希望对你有一定的参考价值。
用Swing做界面，实现一个简单的学生管理系统，具体要求如下：
（1）用Swing做GUI，用文件保存数据（文件格式自定，可以是xml或csv）
（2）实现班级-学生-课程-学分的关系
（3）班级、学生、课程可以动态变更、追加和删除
（4）班级、学生、课程、学分可以排序
（5）画面设计可以自由发挥
我要源代码，各位高手帮个忙吧，越快越好，我下周要交的，多谢了~~~
我的邮箱sizn07@yahoo.com.cn 高手可以发至我邮箱，感激不尽~~~~
楼下那个不会做别进哈，浪费我的时间看你的回答。
各位高手给小女子一点希望吧~~~~~~~~~~
工作量大概10人天，起早贪黑的话3天也差不多……
按照初级软件工程师的薪水标准大概100元每天，你悬赏500块钱没准有人帮你做……
诚心想学的话，给我邮件我再给你发个以前我做的JSP的小作业，你花一两天改改就是了。 参考技术B 草！·还要别人把代码发到你邮箱去啊··！兄弟 其实着个项目蛮简单地 自己慢慢的做吧 学到后面去了就回明白！ 参考技术C 要交作业了吧 急了吧?
如果还有3天时间 你都可以自己完成.
------补充
找身边的同学帮忙吧 参考技术D 借本书吧，参考人家的设计步骤，思想
IDEA+Java+Servlet+JSP+Bootstrap+Mysql实现Web学生成绩管理系统
目录
一、系统介绍
1.开发环境
开发工具：IDEA2018.2
JDK版本：jdk1.8
Mysql版本：8.0.13
2.技术选型
1.后端：使用Java+Servlet进行开发，使用过滤器来验证用户是否登录，使用MVC进行分层。
2.数据库：使用JDBC连接数据库，使用getResourceAsStream获取数据库配置文件的信息。
3.前端：使用Bootstrap作为前端框架来开发，使用到jstl来遍历数据。jsp来展示页面。
3.系统功能
1.学生
1.登录系统
2.个人信息
查询登录密码，查看个人信息，修改个人信息。
3.成绩管理
成绩信息查看
2.教师
1.登录系统
2.个人信息
查询登录密码，查看个人信息，修改个人信息。
3.课程管理
课程信息查看，添加课程信息。
4.成绩管理
成绩信息查看，添加学生成绩。
5.学生管理
查询学生信息，修改学生信息，删除学生信息。
3.管理员
1.登录系统
2.个人信息
3.课程管理
课程信息查看，修改课程信息，删除课程信息，添加课程信息。
4.成绩管理
成绩信息查看，修改学生成绩，删除学生成绩，添加学生成绩，学生总成绩。
5.教师管理
查询教师信息，修改教师信息，删除教师信息，添加教师信息。
6.学生管理
查询学生信息，修改学生信息，删除学生信息，添加学生信息。
7.查询所有账号
查询所有信息，修改信息。
4.数据库
