java继承练习pet

一、题目

二、父类Pet

package pet;

public class Pet {
    
    
	protected String name;
	protected int healthValues;

	public Pet() {
    
    

	}

	public Pet(String name, int healthValues) {
    
    
		super();
		this.name = name;
		this.healthValues = healthValues;
	}

	public String getName() {
    
    
		return name;
	}

	public void setName(String name) {
    
    
		this.name = name;
	}

	public int getHealthValues() {
    
    
		return healthValues;
	}

	public void setHealthValues(int healthValues) {
    
    
		this.healthValues = healthValues;
	}

	public void showPet() {
    
    
		System.out.println("昵称：" + name);
		System.out.println("健康值：" + healthValues);
	}

	public void eat(String food) {
    
    
		System.out.println("吃：" + food);
	}
}

三、子类

1、Dog类

package pet;

import java.util.Scanner;

public class Dog extends Pet {
    
    
	private String strain;

	public Dog() {
    
    

	}

	public Dog(String name, int healthValues, String strain) {
    
    
		super(name, healthValues);
		this.strain = strain;
	}

	public String getStrain() {
    
    
		return strain;
	}

	public void setStrain(String strain) {
    
    
		this.strain = strain;
	}

	public int healthValues() {
    
    
		Scanner sc = new Scanner(System.in);
		System.out.print("是否玩飞盘：");
		String a = sc.next();
		if (a.equals("是")) {
    
    
			healthValues += 1;
		} else {
    
    
			healthValues -= 1;
		}
		return healthValues;
	}

	public void showDog() {
    
    
		System.out.println("昵称：" + name);
		healthValues();
		System.out.println("健康值：" + healthValues);
		System.out.println("品种：" + strain);
	}
}

2、Cat类

package pet;

public class Cat extends Pet {
    
    
	public Cat() {
    
    

	}

	public Cat(String name, int healthValues) {
    
    
		super(name, healthValues);
	}

	public void showCat() {
    
    
		System.out.println("昵称：" + name);
		System.out.println("健康值：" + healthValues);
	}
}

四、测试类Test

package pet;

public class Test {
    
    
	public static void main(String[] args) {
    
    
		Pet p = new Pet("牛牛", 10);
		p.showPet();
		p.eat("草");
		System.out.println();
		Dog d = new Dog("毛毛", 10, "泰迪");
		d.showDog();
		d.eat("狗粮");
		System.out.println();
		Cat c = new Cat("元宝", 10);
		c.showCat();
		c.eat("猫粮");
	}
}
