java饲养员投喂动物

以下是Java中饲养员投喂动物的示例代码：

public class Feeder {
    private String name;

    public void feed(Animal animal) {
        System.out.println(this.name + "喂" + animal.getName());
        animal.eat();
    }

    public String getName() {
        return name;
    }

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

public abstract class Animal {
    private String name;

    public abstract void eat();

    public String getName() {
        return name;
    }

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

public class Cat extends Animal {
    @Override
    public void eat() {
        System.out.println("猫吃食物");
    }
}

public class Dog extends Animal {
    @Override
    public void eat() {
        System.out.println("狗吃食物");
    }
}

使用示例：

Feeder feeder = new Feeder();
feeder.setName("张三");

Cat cat = new Cat();
cat.setName("小猫");

Dog dog = new Dog();
dog.setName("小狗");

feeder.feed(cat); // 输出：张三喂小猫，猫吃食物
feeder.feed(dog); // 输出：张三喂小狗，狗吃食物
