西电java宠物商店程序

很高兴为你提供帮助！以下是一个简单的Java宠物商店程序的示例代码：

import java.util.Scanner;

public class PetShop {
    private static Scanner scanner = new Scanner(System.in);
    private static Animal[] animals = new Animal[10];

    public static void main(String[] args) {
        System.out.println("欢迎来到宠物商店！");
        int choice;
        do {
            System.out.println("请选择您要进行的操作：");
            System.out.println("1. 添加宠物");
            System.out.println("2. 展示所有宠物");
            System.out.println("3. 查找宠物");
            System.out.println("4. 退出");
            choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    addPet();
                    break;
                case 2:
                    showPets();
                    break;
                case 3:
                    searchPet();
                    break;
                case 4:
                    System.out.println("谢谢惠顾！");
                    break;
                default:
                    System.out.println("无效的选择！");
            }
        } while (choice != 4);
    }

    private static void addPet() {
        System.out.println("请输入宠物类型（1. 猫，2. 狗）：");
        int type = scanner.nextInt();
        System.out.println("请输入宠物名称：");
        String name = scanner.next();
        System.out.println("请输入宠物年龄：");
        int age = scanner.nextInt();
        System.out.println("请输入宠物性别（1. 雄性，2. 雌性）：");
        int gender = scanner.nextInt();
        Animal animal = null;
        if (type == 1) {
            System.out.println("请输入猫的品种：");
            String breed = scanner.next();
            animal = new Cat(name, age, gender, breed);
        } else if (type == 2) {
            System.out.println("请输入狗的品种：");
            String breed = scanner.next();
            animal = new Dog(name, age, gender, breed);
        } else {
            System.out.println("无效的宠物类型！");
            return;
        }
        for (int i = 0; i < animals.length; i++) {
            if (animals[i] == null) {
                animals[i] = animal;
                System.out.println("添加宠物成功！");
                return;
            }
        }
        System.out.println("宠物库存已满，无法添加新宠物！");
    }

    private static void showPets() {
        for (Animal animal : animals) {
            if (animal != null) {
                System.out.println(animal);
            }
        }
    }

    private static void searchPet() {
        System.out.println("请输入宠物名称：");
        String name = scanner.next();
        for (Animal animal : animals) {
            if (animal != null && animal.getName().equals(name)) {
                System.out.println(animal);
                return;
            }
        }
        System.out.println("未找到该宠物！");
    }
}

abstract class Animal {
    private String name;
    private int age;
    private int gender;

    public Animal(String name, int age, int gender) {
        this.name = name;
        this.age = age;
        this.gender = gender;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public int getGender() {
        return gender;
    }

    public abstract String getBreed();

    @Override
    public String toString() {
        return "宠物类型：" + getClass().getSimpleName() + "，姓名：" + name + "，年龄：" + age + "，性别：" + (gender == 1 ? "雄性" : "雌性") + "，品种：" + getBreed();
    }
}

class Cat extends Animal {
    private String breed;

    public Cat(String name, int age, int gender, String breed) {
        super(name, age, gender);
        this.breed = breed;
    }

    @Override
    public String getBreed() {
        return breed;
    }
}

class Dog extends Animal {
    private String breed;

    public Dog(String name, int age, int gender, String breed) {
        super(name, age, gender);
        this.breed = breed;
    }

    @Override
    public String getBreed() {
        return breed;
    }
}

这个程序实现了一个简单的宠物商店，用户可以添加、展示、查找宠物。程序中使用了抽象类Animal表示宠物的基本信息，然后定义了猫和狗两个类继承Animal，并在其中添加了品种的属性。用户可以通过输入宠物类型、名称、年龄、性别和品种来添加新宠物，然后查看所有宠物或者通过宠物名称查找特定宠物。
