如何处理同一函数的两个不同对象

// 定义一个父类
class Animal {
    void makeSound() {
        System.out.println("Some sound");
    }
}

// 定义两个子类
class Dog extends Animal {
    @Override
    void makeSound() {
        System.out.println("Bark");
    }
}

class Cat extends Animal {
    @Override
    void makeSound() {
        System.out.println("Meow");
    }
}

public class PolymorphismExample {
    public static void main(String[] args) {
        Animal myDog = new Dog();
        Animal myCat = new Cat();

        myDog.makeSound(); // 输出: Bark
        myCat.makeSound(); // 输出: Meow
    }
}

if (myDog instanceof Dog) {
    Dog specificDog = (Dog) myDog;
    specificDog.makeSound();
}
