学生学籍管理系统含java源代码.docx

1、学生学籍管理系统含java源代码学生学籍管理详细设计 学号：_ 姓名：_ 班级：_1、设计题目：学生学籍管理二：设计内容： 设计GUI学生学籍管理界面，用户可以加入学生信息，并对基本信息进行修改，添加，查询，删除。三：设计要求： 进行简单的学生信息管理。四：总体设计 (1)登陆界面的设计 （2）主窗体的设计 （3）添加学生信息窗体 （4）查询学生信息窗体 （5）修改学生信息窗体 （6）删除学生信息窗体 （7)事件响应的处理五：具体设计（1）程序结构的说明：A.入口程序：student.java;B.登陆界面程序：mainframe.java;C.主窗体程序：interfac.java;D.添加

2、信息窗口程序：tj.java;E.修改信息窗口程序：xg.java;F.查询信息窗口程序：cx.java;G.删除信息窗口程序：sc.java;H.程序数据连接：DatabaseConn.java;(2)程序代码及分析说明A.程序源代码（已提交）“进入系统”，然后登陆界面消失；出现要操作的界面（屏幕左上角）。“添加信息”按钮，将信息加入xinxi表中。“修改信息”按钮（如果数据库中不存在此学号，则弹出对话框“无此学生信息”），若有则修改。“删除信息”按钮，弹出确认删除对话框，即可删除该生信息。“信息查询”按钮，在相应的文本区里显示查询的信息。H:源代码/student.java:程序的入口。初
