Java集合写的通讯录

这是我们这一学期的实践大作业~

花了大概七八个小时写出来的......

用Vector集合储存信息，实现了增删改查和排序、退出六个基本功能~

说实话感觉多余且麻烦，但要求是这样，我也没办法......

一共五个文件，分别为Person、Menu、App、Operate、TelNoteRegex:

Person类为实例类

Menu类定义一个主菜单和各个子菜单的方法

App类只有一个作用，在主方法中创建Menu类的对象，并调用主菜单方法......

Operate类就是各个具体操作的实现方法

TelNoteRegex类定义了对信息进行验证的方法，毕竟输入的信息不能什么都接受~

 

好了下边贴代码：

 

App.java

    public static void main(String[] args)
    {
        Menu menu = new Menu();
        menu.mainMenu();
    }

其实Person类中定义的Id属性根本就没用上，因为在后边的排序操作时所有的信息的顺序都可能会被打乱......所以正在显示全部信息的时候才给它们加上了Id，这个Id是在showAll()方法体内定义的，在其他需要输出的地方也都是这样解决的......我才疏学浅，暂时没想到更好的解决办法~如果有大神有办法，还请在评论区中不吝赐教！
