Quizplus · Accepted Answer

Polymorphism in object-oriented programming allows a reference of a base class type to refer to an object of a derived class type. The actual method that gets invoked is determined by the type of the object that the reference points to, not by the type of the reference itself. This enables one to use a single reference type to invoke methods on objects of different derived types, depending on the actual object type at runtime.
