java通讯录设计代码,通讯录管理系统java课程设计源代码

用JAVA设计一个通讯录，保存读者信息。

wowo我又写了一半的代码,完成了添加用的是窗口的图形化界面,要么??

java使用顺序表制作电子通讯录,实现添加,删除和排序的功能.

翻了半天找到以前写的，只写了部分，你可以参考一下

public String getStuName(){return stuName;}

}

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

实现一个小型通讯录。Java
