java通讯录

时间：2023-03-08 18:33:16

（1）设一个通信录由以下几项数据信息构成：

数据项               类型

姓名                  字符串

地址                  字符串

邮政编码              字符串

电话号码             字符串

（2）1．主要功能：

（1） 能建立、查询、修改和增删学生通讯录

（2） 能够按多种方式进行查询

（3）界面友好，易于操作

通讯录管理系统的设计与实现 

                             学生姓名：陈万洲  指导老师：文斌

 

【中文摘要】  这个基于java编写的个人通讯录管理系统含有添加、删除、查找等基本功能，采用的是JDBC-ODBC桥实现数据库的连接,ODBC数据源名称chengwz.mbd。本课程设计主要解决通讯录应用的管理问题, 设计开发一个简单的通讯录系统 ，实现新建联系人，不同方式查找信息，删除信息，修改信息，联系人头像，退出系统等功能。在课程设计中，程序通过调试运行，初步实现了设计目标，并且经过适当完善后，将可以应用在通讯录应用的管理中，解决实际问题。用户和密码是123和123，系统所用的图片，自己用Photoshop制作的

关键词 ：通讯录、java、通讯录应用、个人通讯录管理系统、添加、删除、查找，数据库。
