DogTest类：



package com.hp.test07;

import java.util.Scanner;

public class DogTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Dog dog=new Dog();
        
        System.out.println("----------------欢迎来到宠物店--------------");
        System.out.println("请选择需要领养的宠物品种：1.哈巴狗  2.牧羊犬");
        Scanner input=new Scanner(System.in);
        dog.setStrain(input.nextLine()); 
        
        System.out.println("请给你的爱犬起个好听的名字：");      
        Scanner input1=new Scanner(System.in);
        dog.setName(input1.next());
        
        System.out.println("设定健康值：eg:80");
