java的面向对象的数据组织，封装和对象数组的应用。

Question

定义一个快递员类DeliveryMan，包括姓名、电话和配送区域三个数据成员，其他set/get方法和构造方法。（2）定义一个测试类Client，创建一个快递员的数组，用直接赋值的形式保存不少于5个的快递员信息（数据自拟，地域要求查找地图保证真实）。在控制台输入快递地址，为其匹配相应的快递员，输出其姓名和联系方式；无法匹配时给出提示。可多次查询，输入quit后结束查询

Answer 1

import java.util.Scanner;

public class Client {

	public static void main(String[] args) {
		DeliveryMan dm[] = {
				new DeliveryMan("张三", "13888888888", "章贡区"),
				new DeliveryMan("李四", "13666666666", "蓉江新区"),
				new DeliveryMan("王五", "13777777777", "黄金开发区"),
				new DeliveryMan("丽丽", "13999999999", "赣县区"),
				new DeliveryMan("张师傅", "13033333333", "南康区")
		};
		String area="";
		Scanner input = new Scanner(System.in);
		while(true) {
			System.out.println("请输入区域：");
			area = input.next();
			if(area.equalsIgnoreCase("quit")) {
				break;
			}
			Boolean bExist=false;
			for(int i=0;i<dm.length;i++) {
				DeliveryMan man = dm[i];
				if(man.getArea().equals(area)) {
					System.out.println(man);
					bExist = true;
					break;
				}
			}
			if(!bExist) {
				System.out.println("快递员不存在，请重新输入：");
			}
		}
