JAVA学生信息管理系统实验报告

JA V A程序设计实验报告学号：姓名：班级：实验、Java课程设计--------学生信息管理系统一、实验目的1．掌握Java基本语法2．理解面向对象编程特点3．理解Java I/O编程4．掌握Java图形界面编程5．掌握Java与不同数据库进行连接二、预习内容Java的基本语法知识、类和对象、Java Swing图形界面编程、Java I/O处理以及Java与数据库连接操作三、实验设备与环境通过局域网互联，安装Windows 2000/XP操作系统环境的JDK 1.6，my eclipse 或者EditPlus编程工具。

并安装MySQL数据库四、实验内容编写并调试运行Java程序，进行设计，掌握Java开发的基础。

五、实验任务设计学生信息管理系统。

要求包括1. 登陆模块：设立超级管理员权限，用户可以根据不同的权限登陆系统，超级管理员可以对学生信息进行增、删、改、查操作。

而普通用户只可以查找学生信息。

2. 包括学生添加信息模块、学生信息删除模块、学生信息修改模块和学生信息查询模块3.对于管理员，可以对管理员进行添加、删除以及修改密码等操作。

六、实验报告（要求独立完成参考程序的代码、编译、调试与运行）1、程序清单：1.1程序模块清单package Pan;import java.awt.event.ItemListener;import javax.swing.*;import ponent;import java.awt.BorderLayout;import java.awt.FlowLayout;import
