用java编写一个通讯录管理系统并连接数据库,实现通讯录的基本功能

public class CloudLed {

boolean m_isOn;

Camera m_Camera;

public boolean getIsOn() { return m_isOn; }

public CloudLed()

{

m_isOn = false;

}

public void turnOn()

{

if(!m_isOn)

{

m_isOn = true;

try

{

用Java编辑通讯录

用JAVA编写一个班级通讯录

1)java form,jlable 、textField、button 神马 的 GridBagLayout布局搞一发

2)JDBC 往数据库搞一搞;

3)数据库排序取出,或者取出后代码排个序

4)步骤2已经写入数据库,下次从数据库区,不会丢失

5)搞一个方法,专门用于显示,每计算一次,调用这个方法

另;应该搞个登陆的,管理总要有权限控制的

个人通讯录管理 JAVA课程设计

通讯录管理系统.. 都不知道怎么做 有高手帮忙下 . 我有,包括单机版还有网络版,刚做完不久。可是你给的分太低。考虑一下吧

基于Java的个人通讯录的文献综述和开题报告

可以使用Baidu Hi通知我

有时间可能完成你所面临的任务

同样的要求也可能通知我

基于Java的个人通讯录的文献综述和****
