Polymorphism
Prerequisites: Inheritance
Animal[] animals = { new Dog("Rex"), new Cat("Tom") };
foreach (Animal a in animals) {
a.MakeSound(); // runs Dog's or Cat's version, whichever it is
}
Rex barks
Tom meows
Exactly as in Java, code written against the base type Animal
automatically works correctly with any subtype, decided at runtime
based on the object's actual type.
