测试类：

import java.util.Scanner;

public class Text01 {
    static Scanner input = new Scanner(System.in);
    public static void main(String[] args) {
        String sex;
        int love = 60;
        System.out.println("欢迎来到宠物商店！");
        System.out.println("请输入要领养的宠物的名字：");
        String name = input.next();
        System.out.print("请选择要领养的宠物类型：(1、狗狗  2、企鹅)");
        int choose = input.nextInt();
        switch (choose) {
        case 1:
            System.out.println("请选择狗狗的性别：(1、雄性   2、雌性)");
            int choose1 = input.nextInt();
            if(choose1 == 1) {

            Dog dog = new Dog(health, love, name, sex);
