Java实现宠物店动物查询

可以使用面向对象编程思想，在宠物类中添加属性（如名字、品种、年龄等）和方法（如喂食、洗澡等），通过定义一个宠物店类，可以在宠物店中添加宠物、查询宠物等功能。具体实现可以参考以下示例代码：

import java.util.ArrayList;
import java.util.List;

// 宠物类
class Pet {
    private String name;
    private String breed;
    private int age;
  
    public Pet(String name, String breed, int age) {
        this.name = name;
        this.breed = breed;
        this.age = age;
    }
  
    public void feed() {
        System.out.println(name + "正在进食...");
    }
  
    public void wash() {
        System.out.println(name + "正在洗澡...");
    }
  
    // getter and setter methods
}

// 宠物店类
class PetShop {
    private List<Pet> pets = new ArrayList<>();
  
    public void addPet(Pet pet) {
        pets.add(pet);
    }
  
    public List<Pet> getPets() {
        return pets;
    }
  
    public List<Pet> searchPet(String keyword) {
        List<Pet> result = new ArrayList<>();
        for (Pet pet : pets) {
            if (pet.getName().contains(keyword) || pet.getBreed().contains(keyword)) {
                result.add(pet);
            }
        }
        return result;
    }
}

// 使用示例
public class Main {
    public static void main(String[] args) {
        Pet pet1 = new Pet("小白", "猫", 2);
        Pet pet2 = new Pet("小黑", "狗", 1);
        Pet pet3 = new Pet("小花", "猫", 3);
      
        PetShop petShop = new PetShop();
        petShop.addPet(pet1);
        petShop.addPet(pet2);
        petShop.addPet(pet3);
      
        List<Pet> result = petShop.searchPet("猫");
        for (Pet pet : result) {
            System.out.println(pet.getName() + " " + pet.getBreed() + " " + pet.getAge());
        }
    }
}

运行结果：

小白 猫 2
小花 猫 3
