speak() is same because according to compiler both methods are called on Mammal reference but the output for both method calls is different because at runtime JVM knows what object a reference is holding and JVM calls the method on the object and this is why Method Overriding is known as Dynamic Polymorphism.26 Ara 2013
Read moreWhat is dynamic polymorphism in C?
Dynamic Polymorphism C# allows you to create abstract classes that are used to provide partial class implementation of an interface . Implementation is completed when a derived class inherits from it. Abstract classes contain abstract methods, which are implemented by the derived class.
Read moreWhat is an example of dynamic polymorphism?
Method overloading is an example of static polymorphism, while method overriding is an example of dynamic polymorphism. An important example of polymorphism is how a parent class refers to a child class object. In fact, any object that satisfies more than one IS-A relationship is polymorphic in nature.
Read moreWhy is polymorphism necessary?
Polymorphism is inherently good. It refers to something having many forms, referring to both objects and methods. Polymorphism allows you to code to an interface that reduces coupling, increases reusability, and makes your code easier to read .
Read moreHow is polymorphism used in OOP?
Polymorphism is the method in an object-oriented programming language that performs different things as per the object’s class, which calls it . With Polymorphism, a message is sent to multiple class objects, and every object responds appropriately according to the properties of the class.
Read moreWhere is polymorphism used in C++?
The word polymorphism means having many forms. Typically, polymorphism occurs when there is a hierarchy of classes and they are related by inheritance. C++ polymorphism means that a call to a member function will cause a different function to be executed depending on the type of object that invokes the function .
Read moreWhat is polymorphism and types?
Polymorphism is the ability to process objects differently on the basis of their class and data types . There are two types of polymorphism in Java: compile time polymorphism and run time polymorphism in java. This java polymorphism is also referred to as static polymorphisms and dynamic polymorphisms.
