9. Covariant Return Types: Specificity

Scenario

Can an overriding method return a different type than the original? Yes, if it's a subclass of the original return type.

Code Block

class Food {}
class Pizza extends Food {}

class Restaurant {
    Food order() {
        return new Food();
    }
}

class Pizzeria extends Restaurant {
    @Override
    Pizza order() { // Covariant return type (Pizza is a Food)
        return new Pizza();
    }
}

public class Main {
    public static void main(String[] args) {
        Restaurant res = new Pizzeria();
        Food f = res.order();
        System.out.println("Ordered: " + f.getClass().getSimpleName());
    }
}
