    我是一个java初学者,所以很多地方都写的很糟,首先谢谢 “唐”给我的练习题,这是完成所有功能后第一时间发的,所以很多该提取的方法和类都没有提取,主要是能够更清晰的看到整个结构,希望一步一个脚印能慢慢做的更好。加油!

    这是运行结果

    代码:

    importjava.util.Scanner;

    /**

    @Yq

    【电话本管理系统v1.0】

    1.添加    2.删除    3.修改    4.查询所有  5.根据姓名查询    6.退出

    */

    /**

    *对电话本数据的操作接口

    */

    interfaceTelBookDAO {

        publicabstractvoidadd();

        publicabstractvoiddelete();

        publicabstractvoidexit();

    }
