学生信息管理系统（Java实训）

学生信息管理系统（Java实训）

项目源码下载地址：
https://github.com/Chien-W/Student-management-system-simple-.git

特别注意：使用这个系统，需要在本地建立好对应的数据库的表！表的式样在github文件中。并且增删改查使用的是SQL server语句，若你使用的是My SQL，可能需要自己修改一下增删改查中对数据库操作的语句。

实训目的：

掌握类的定义，对象的使用，集合以及文件读写操作。

实训要求：

（1）要使用 Java 的 GUI 设计出计算器界面。（2）能够保存
学生信息到文本文件，并且能从文件打开。可以用 Vector、ArrayList、
LinkedList 等形式存储，能用 MySQL/SQL Server 等数据库存储则更佳。（3）通过界面按钮实现学生信息的管理，实现学生信息的增加、删除、修改、查询等功能。

本题代码和类比较多，win开头的文件和test都是window build的类。其他都是普通类。
