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;
}
}

}
for (int i = index; i < customers.length - 1; i++) {
customers[i] = customers[i + 1];
}
customers[total] = null;
total--;
return true;
}
/**
