Java实训项目：GUI学生信息管理系统（2017）

java实训项目（含源码和文档）java实训项目（含源码和文档）java实训项目（含源码和文档）java实训项目（含源码和文档）

根据韩顺平老师的视频整理而成，简单的java GUI编程。

java的项目学生信息管理系统实战资料，有项目分析和项目的实现，项目讲解，项目计划，数据库设计，各个界面的设计

包含数据库sql文件，带有增删改查学生信息功能，还有分页功能，可运行出来，亲测

C#、面向对象、图形化界面，连接数据库、、、附student数据库在里面。

本系统作为servlet和jsp课程设计只开发了部分功能，由Servlet+jsp技术开发，服务器tomcat，数据库mysql，前端BUI，无使用现有框架。融入MVC的设计模型，实现了Spring mvc的前端控制器dispatcher，使开发功能变简单 。在不改变本系统的整体架构下，可参照本系统已有功能对本系统进行更改或扩充。如有问题请加QQ：997977130

基于java 的学生信息管理系统 数据库采用mysql 适合新手练手的小项目

设计一个GUI界面的学生信息管理系统，方便保存学生的部分信息。 有五类功能： 1、 增加学生信息：输入姓名、学号、年龄、手机号 2、 修改学生信息：输入新的姓名、学号、年龄、手机号 3、 删除学生信息：以学号为索引 4、 查询学生信息：以学号为索引 5、 显示学生信息：一条一条整页显示。
