Java网络编程实践课程设计

1、精品文档J av a 网 络 编 程 实 践课程设计说明书课程名称： Java 网络编程课程设计题目：基于 C/S 的学生信息管理姓名：学号：教学班号 :指导教师：王 小 刚兰州交通大学软件科学与工程系二13年12月27日。1欢迎下载精品文档。2欢迎下载精品文档任务书实现应用，可以通过网络在客户端对存放在服务器端的学生信息表（至少包含学号、姓名、性别、年龄、籍贯等字段）学生纪录增、删、改、查，并返回结果。要能通过菜单选择功能。基于Socket ，多客户端使用多线程，以能同时从多个客户端执行功能。必须提供友好直观、布局合理的图形界面选择功能、显示信息和填写修改信息。成员及分工列表图形界面设计者：

2、数据库设计者：Socket设计者：多线程设计者：项目简述和目的熟悉 JAVA 语法，掌握图形化界面、多线程、 网络、 数据库等综合编程，掌握用编程语言开发由若干功能组成的小型项目的基本流程，增强动手实践能力，巩固和加强书本知识的学习，体会 JAVA编程的特点。解题基本思路设计的信息管理系统中的窗体部分，没有使用菜单，而是按钮。菜单虽然简单，方便，但我认为在窗体里运用按钮是有必要的，这样可以方便添加、删除，修改等动作，通过一步步地做，慢慢的集合，比较的清晰，还显得比较的有层次感 . 利用 Swing 设计图形界面利用 Access 表设计数据库，利用 socket 设计网络信息管理模块分析和设计
