Java大作业实验报告
目 录

一、实验目的和要求

二、实验环境、内容和方法

三、源代码

四、调试与运行结果

五， 总结

一、实验目的和要求
1、定义一个学生基本信息管理类，有姓名、年龄、籍贯、电话号码，实现增、删、改、查4个方法。（可以使用MySql数据库实现，也可以使用集合类。）
2、在main函数中，实例化学生管理类，并根据菜单的选项分别调用4个方法。
3、该系统要求实现一个图形界面。

二、实验环境、内容和方法
实验内容：

1. 点击查看信息按钮 查看数据库中全部信息
2. 点击添加数据按钮 添加数据 然后点击查看信息按钮 查看数据是否添加到数据库中
3. 点击删除数据按钮 输入想删除的数据 然后点击查看信息按钮 查看数据是否在数据库中被删除
4. 点击更改数据按钮 输入想更改的数据 然后点击查看信息按钮 查看数据库内部的数据是否被更改了
5. 点击关闭系统按钮 查看是否关闭了该程序

实验方法：

通过上机操作完成各内容。

实验环境：

笔记本电脑 Windows10操作系统 java15.0环境 mysql8.0

三、源代码
界面 与 数据库储存查找删除添加内部逻辑代码

五、总结

通过本次java大作业的制作过程，我已经初步掌握了java的用户图形界面和如何用java操控mysql数据库的相关知识，我深刻体会到了，一个代码体的逻辑严谨的重要性，以后我们在写代码的准备过程中，需要想好整体布局，然后把整体拆成一个个小的模块，然后分模块进行对于代码的编写，最后把每一个模块的代码结合起来，最终形成一个完整的程序。
