电子宠物系统

功能：选择宠物、取名字、定义健康值与亲密度（只能在0-100之间取值，否则定义为60）等

主代码：

package com.bdqn;

import java.util.Scanner;

public class PetTest {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        System.out.println("***欢迎来到电子宠物系统***");
        System.out.println("请输入您想要领养的宠物（1、狗狗 2、猫 3、企鹅）：");
        int choose = s.nextInt();
        if(choose == 1){
            Dog dog = new Dog();
            System.out.println("请输入您想要取的宠物姓名：");
            dog.setName(s.next());
            System.out.println("请输入狗狗的健康值（0-100）：");
            dog.setHealth(s.nextInt());
            System.out.println("请输入狗狗的亲密度（0-100）：");
            dog.setLove(s.nextInt());
            System.out.println("请输入您想领养的狗狗种类（1、拉布拉多 2、博美）：");
            dog.setStrain(s.nextInt());
            dog.print();
        }else if(choose == 2){
            Cat cat = new Cat();
            System.out.println("请输入您想要取的猫姓名：");
            cat.setName(s.next());
            System.out.println("请输入猫的健康值（0-100）：");
            cat.setHealth(s.nextInt());
            System.out.println("请输入猫的亲密度（0-100）：");
            cat.setLove(s.nextInt());
            System.out.println("请输入您想领养的猫的颜色(白色、蓝色、花色)：");
            cat.setColor(s.next());
            cat.print();
        }else{
            Penguin penguin = new Penguin();
            System.out.println("请输入您想要取的企鹅姓名：");
            penguin.setName(s.next());
            System.out.println("请输入企鹅的健康值（0-100）：");
            penguin.setHealth(s.nextInt());
            System.out.println("请输入企鹅的亲密度（0-100）：");
            penguin.setLove(s.nextInt());
            System.out.println("请输入您想领养的企鹅的性别（1、Q仔 2、Q妹）：");
            penguin.setSex(s.nextInt());
            penguin.print();
        }
    }
}

父类代码：

        return name;
    }

    public void setHealth(int health) {
        if(health < 0 || health > 100){
            health = 60;
        }
        this.health = health;
    }
    public int getHealth() {
        return health;
    }

        }
        this.love = love;
    }
    public int getLove() {
        return love;
    }

    public void print(){
        System.out.println("宠物的自白：");

    }
}

            return;
        }
