/*
18、美发店管理系统
题目描述：
设计完成对美发店的简单管理。
功能需求：
(1) 定义顾客类，属性有：会员卡号、姓名、性别、电话等信息和相关的对属性做操作的行为。
(2) 定义员工类：属性有：编号、姓名、性别、电话、美发项目（理发、烫发、洗发）等信息和相关的对属性做操作的行为。
(3) 定义美发类：属性有各种美发项目的收费标准和相关的对属性做操作的行为。
(4) 定义一个管理类。
(5) 添加、删除、修改、查询顾客信息和雇员信息，要求编号要唯一，如果添加了重复编号的记录时，则提示数据添加重复并取消添加；删除、修改、查询时，如果没有对应人员记录，则提示“记录为空！”并返回操作。
(6) 使用外部文件或数据库存储相关数据。

对象序列化出了问题

[qq_39936465]

你全程都没有关流操作吧

[捏造的信仰]

楼主要学会贴代码

public class Demo {
    public static void main(String[] args) {
        if (args.length == 0) {
            System.out.println("no args.");
        }
    }
}

像楼主的代码层级多，又没有排版，没法看。
