一道java编程题，请各位大神前来解答
代码如下：

}

Java优化宠物系统 求代码 求注解
四个类：Pet Dog Penguin PetTest（测试类）
1、Pet类:
/**
* 宠物类
* Created by LuHuan on 2017/7/27.
*/
public class Pet {
String name = "null";
int health = 100;//健康值
int love = 0;//亲密度
//打印输出宠物信息
public void print() {
System.out.print("我的名字叫" + name + "，我的健康值是：" + health + "，我和主人的亲密程度是" + love + ".");
}
public String getName() {
return name;
}
public int getHealth() {
return health;
}
public int getLove() {
return love;
}
}
2、Dog类：
/**
* 狗狗类
* Created by LuHuan on 2017/7/27.
*/
public class Dog extends Pet {
String strain = "拉布拉多犬";//品种
public String getStrain() {
return strain;
}
//重写宠物的自白方法
@Override
public void print() {
super.print();
System.out.println("我是一只" + strain);
}
}
3、Penguin类：
/**
*企鹅类
* Created by LuHuan on 2017/7/27.
*/
public class Penguin extends Pet {
String sex = "Q仔";//性别
public String getSex() {
return sex;
}
//重写宠物的自白方法
@Override
public void print() {
super.print();
System.out.println("我的性别是" + sex);
}
}
4、PetTest测试类：
/**
* 测试类
* Created by LuHuan on 2017/7/27.
*/
public class PetTest {
public static void main(String[] args) {
Dog dog = new Dog();
dog.name = "欧欧";
Penguin pgn = new Penguin();
pgn.name = "楠楠";
System.out.println("宠物的自白：");
dog.print();
System.out.println("宠物的自白：");
pgn.print();
}
}
5、输出：
宠物的自白：
我的名字叫欧欧，我的健康值是：100，我和主人的亲密程度是0.我是一只拉布拉多犬
宠物的自白：
我的名字叫楠楠，我的健康值是：100，我和主人的亲密程度是0.我的性别是Q仔
JAVA代码主人喂宠物吃东西狗只吃骨头猫只吃鱼求代码用多态
/*
animal是个抽象方法，Cat 和Dog extends 这个就是用的多态
*/
package Test;
public class Test{
public static void main(String[] args){
Feeder feeder = new Feeder();
feeder.feedAnimals();
}
}
abstract class Animal{
public abstract void eat(String s);
}
class Dog extends Animal{
private final String FOOD = "bone";
@Override
public void eat(String s){
if (s == FOOD)
System.out.println("Dog is eating bones");
else
System.out.println("Not "+this.FOOD+", Dog don't want to eat");
}
}
class Cat extends Animal{
private final String FOOD = "fish";
@Override
public void eat(String s){
if (s == FOOD)
System.out.println("Cat is eating fishes");
else
System.out.println("Not "+this.FOOD+", Cat don't want to eat");
}
}
class Feeder{
private final String[] FOODS = {"fish", "bone", "shit"};
private Animal cat;
private Animal dog;
Feeder(){
dog = new Dog();
cat = new Cat();
}
public void feedAnimals(){
System.out.println("Feeding animals...");
String food;
for(int i = 0; i FOODS.length; i++){
food = FOODS[i];
if(food == "fish")
this.cat.eat(food);
else if(food == "bone")
this.dog.eat(food);
else{
System.out.println("Not Fishes or Bones, is "+ food);
}
}
System.out.println("Done!");
}
}
