这里的Customer是什么类型?

在intialCustomer123中m.addCustomer();
这里怎么把实参传递给形参aaaaaaaaaaaaaaaaaaaaaaaaaaaaa

public class Customer123 {
Customer[] Customer=new Customer[30];

public void addCustomer(Customer cust){
    for(int i=0;i<Customer.length;i++){
        if(Customer[i]==null){
            Customer[i]=cust;
            break;
        }
    }
}

public void showCustomer(){
    for(int i=0;i<Customer.length;i++){
        if(Customer[i]!=null){
            System.out.println(Customer[i]);
        }
    }
}

}

import java.util.Scanner;

public class intialCustomer {

public static void main(String[] args) {
    Customer n=new Customer();
    n.name="小明";
    n.age=22;
    n.huiyuan="是";

    Customer123 m=new Customer123();
    Scanner input=new Scanner(System.in);

    boolean con=true;
    do{
        System.out.println("请输入要添加的姓名:");
        String name=input.next();
        m.addCustomer();
        System.out.println("要继续吗?(y/n):");
        String answer=input.next();
        if("n".equals(answer)){
            con=false;
        }
    }while(con);

    System.out.println("添加后的信息:");
    m.showCustomer();

}

}

Customer[] Customer=new Customer[30];

Customer是个数组啊。。。。老兄命名规范点，可读性太差了

add的时候没有传递参数哦，，，，

英语单词别乱用,命名规范多看看,该小写的要小写,更要注意见名之意,至于类型,引用数据类型
