If I've cast a subclass as its superclass, and call a method that was overridden in the subclass, does it perform the overridden or original method?

Question

Consider:

Dog is a subclass of Animal, and Dog overrides Animal.eat()

Animal[] animals = getAllAnimals();
for (int i = 0; i < animals.length; i++) {
    animals[i].eat();
}

If Animal.eat() is overriden by Dog.eat(), which one is called when the method is called from an identifier of type Animal (animals[i]?)

Answer 1

The subclass method will be called. That's the beauty of polymorphism.
