What is polymorphism

Question

I dont understand what is polymorphism actually do?

Tamal Marick · Answer

Generally, the ability to appear in many forms. In object-oriented programming, polymorphism refers to a programming language's ability to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes.

Ganesh Sanap · Answer

Polymorphism is one of the fundamental concepts of OOP. Polymorphism provides following features: It allows you to invoke methods of derived class through base class reference during runtime. It has the ability for classes to provide different implementations of methods that are called through the same name. Polymorphism is of two types: Compile time polymorphism/Overloading Runtime polymorphism/Overriding References: https://www.c-sharpcorner.com/UploadFile/puranindia/polymorphism-in-C-Sharp/ https://www.codeproject.com/Articles/602141/Polymorphism-in-NET https://www.c-sharpcorner.com/UploadFile/ff2f08/understanding-polymorphism-in-C-Sharp/

Jayanth Reddy · Answer

In General "Poli" means "multi" and "Morphism" means "changing its form" So the word PolyMorphism means "changing multiple forms" In terms of "Object Orientation" we can define the same as writing same name for multiple methods. Example:Consider method overriding(declaring the method with the same name in childs class which was already declared in its parent class).

Hi, Everyone define the definition of Polymorphism a/c to his own view. I am beliveing on microsoft. I my suggestion is that microsoft website and read about it. Gothrough the below link. https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/polymorphism

Polymorphism: Same entity in different shapes. Overriding & Overloading is the best I example of polymorphism & polymorphic properties.

Hi Saad, Polymorphism, in C#, is the ability of objects of different types to provide a unique interface for different implementations of methods. It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on object type at run time.

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object

Kapil Gaur · Answer

Hi Saad, Polymorphism is one of the core concepts of Obejct Oriented Programming. It means one name and multiple forms. So when we talk of polymorphism here in C#, We have two types of polymorphism i.e., static polymorphism(Overloading) and runtime polymorphism(Overriding). In static polymorphism you can have two methods with same name but different parameters in same class. The behaviour of method in such case is known at compile time. Hence this is known as overloading AKA static polymorphism. In overriding, if you have a method in class A and you have inherited class A into class B. Then method A of class A if you override in class B then that becomes overriding AKA runtime polymorphism because behavior of this method will be known at runtime only. Tell me if you are satisfied with answer. Otherwise i will explain more about it.

Saad Ali, Just watch this videos, you will understand easily Ploymorphism allows you to invoke derived class methods through a base class reference during runtime. https://www.youtube.com/watch?v=4a_iTOtGhM8 Hope you understand Thanks

Sonu Gupta · Answer

Polymorphism is nothing but assigning value in a child class to something that was already declared in the parent class. Simply, polymorphism takes more than one form

Devesh Mehta · Answer

As the name suggests itself polymorphism = poly + morphism poly= many morphism = forms It means that one object has the ability to take many forms Real time example of polymorphism is A Man act as a Son of his father , That man act as a employee in office. Mainly there are 2 types of polymorphism 1) Compile time polymorphism : In this type call is resolved by the compiler. It is also called as Static polymorphism or Early binding. 2) Run time polymorphism : In this type call is not resolved by the compiler. It is also called as Dynamic polymorphism or Late binding.

Harsh Shah · Answer

In a programming language that exhibits polymorphism, objects of classes belonging to the same hierarchical tree (inherited from a common base class) may possess functions bearing the same name, but each having different behaviors. As an example, assume there is a base class named Animals from which the subclasses Horse, Fish and Bird are derived. Also assume that the Animals class has a function named Move, which is inherited by all subclasses mentioned. With polymorphism, each subclass may have its own way of implementing the function. So, for example, when the Move function is called in an object of the Horse class, the function might respond by displaying trotting on the screen. On the other hand, when the same function is called in an object of the Fish class, swimming might be displayed on the screen. In the case of a Bird object, it may be flying.
