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
JAVA通讯录 求一个JAVA编写的通讯录，基本的就可以。
具体方法如下：
1、定义封装一条记录java通讯录界面代码的实体类
2、根据实际系统容量，定义一个数组
3、完成系统中显示全部记录的逻辑
4、完成系统中添加一条记录的逻辑
5、完成系统中删除一条记录的逻辑
6、完成系统中修改一条记录的逻辑
7、全部代码：
import java.util.Scanner;
class Contact {
String cellPhone;
String name;
}
public class Main {
private static void menu () {
System.out.println("************** 菜单 ******"
+ "************");
System.out.println(" 1.显示全部通讯录");
System.out.println(" 2.增加一条记录");
System.out.println(" 3.删除一条记录");
System.out.println(" 4.修改一条记录");
System.out.println(" 0.退出");
}
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
Contact[] contacts = new Contact[200];
int size = 0;
String cmd = "";
do {
menu();
System.out.print("请输入你得选择：(0-4)");
cmd = scn.nextLine();
if (cmd.equals("1")) {
if (size == 0)
System.out.println("系统当前无记录java通讯录界面代码！");
else
for (int i = 0; i size; i++) {
System.out.println(contacts[i].name + ":"
+ contacts[i].cellPhone);
}
} else if (cmd.equals("2")) {
System.out.print("请输入手机号：");
String cellphone = scn.nextLine();
System.out.print("请输入姓名：");
String name = scn.nextLine();
Contact contact = new Contact();
contact.cellPhone = cellphone;
contact.name = name;
if (size contacts.length) {
contacts[size++] = contact;
System.out.println("添加成功！");
} else {
System.out.println("你最多只能添加" +
contacts.length + "条记录");
}
} else if (cmd.equals("3")) {
System.out.print("请输入要删除的手机号：");
String cellphone = scn.nextLine();
int index = -1;
for (int i = 0; i size i contacts.length;
i++) {
if (contacts[i].cellPhone.equals(cellphone)) {
index = i;
break;
}
}
if (index == -1) {
System.out.println("该记录不存在！");
} else {
for (int i = index; i size; i++) {
contacts[index] = contacts[index + 1];
}
contacts[size - 1] = null;
size--;
System.out.println("删除成功！");
}
} else if (cmd.equals("4")) {
System.out.print("请输入要修改的手机号：");
String cellphone = scn.nextLine();
int index = -1;
for (int i = 0; i size i contacts.length;
i++) {
if (contacts[i].cellPhone.equals(cellphone)) {
index = i;
break;
}
}
if (index == -1) {
System.out.println("该记录不存在！");
} else {
System.out.print("请输入姓名：");
String name = scn.nextLine();
contacts[index].name = name;
}
}
} while (!cmd.equals("0"));
System.out.println("退出成功！");
scn.close();
System.exit(0);
}
}
求！ 用JAVA编写一个通讯录，只要有最基本的添加、查找就可以
开发环境JBuilder2005 SQL server2003 SP3连接方士直链java通讯录界面代码，如果直链不上改桥链java通讯录界面代码，参考

userQQ VARCHAR(20) NOT NULL,
USEREMAIL VARCHAR(20) NOT NULL,
