对象数组实现添加和显示客户信息

public class Customer {
private String name;
private int age;
private boolean flag;//是否有会员卡
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public boolean isFlag() {
return flag;
}
public void setFlag(boolean flag) {
this.flag = flag;
}
}
import java.util.Scanner;
public class CustomerBiz {
//定义一个对象数组
private Customer[] cus = new Customer[30];

public static void main(String[] args) {
	// TODO Auto-generated method stub
	Scanner sc = new Scanner(System.in);	
	CustomerBiz biz = new CustomerBiz();
	
	for (int i = 0; i < 2; i++) {
		Customer cus = new Customer();
		System.out.print("请输入名称:");
		//给属性赋值
		cus.setName(sc.next());
		System.out.print("年龄:");
		cus.setAge(sc.nextInt());
		//添加客户对象
		biz.addCustomer(cus);
	}
	//展示
	biz.showCustomers();
}

/**
 * 添加对象
 * @param customer
 */
public void addCustomer(Customer customer){
	for (int i = 0; i < cus.length; i++) {
		if (cus[i]==null) {
			cus[i]=customer;
			break;
		}
	}
}
/**
 * 显示客户信息

public void showCustomers(){
	System.out.println("客户信息:");
	for (Customer customer : cus) {
		if(customer != null){
			System.out.println(customer.getName()+"	"+customer.getAge()+"	"+customer.isFlag());
		}
	}		
}
