java客户信息管理软件

需求说明：

模拟实现基于文本界面的《客户信息管理软件》
该软件能够实现对客户对象的插入、修改和删除（用数组实现），并能够打印客户明细表。

封装类：

public class Customer {
    private String name;//姓名
    private char gender;//性别
    private int age;//年龄
    private String phone;//电话
    private String email;//email

    public Customer() {
    }

    public Customer(String name, char gender, int age, String phone, String email) {
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.phone = phone;
        this.email = email;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public char getGender() {
        return gender;
    }

    public void setGender(char gender) {
        this.gender = gender;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}
