Inheritance and Polymorphism Objects are often categorized into groups that share similar characteristics. When you execute the above c# program, you will get the result like as shown below. Polymorphism is a Greek word, meaning \"one name many forms\". The programming paradigm where everything is represented as an object is known as truly object-oriented programming language. Here, we defined a GetInfo method with a virtual keyword in the base class to allow derived class to override that method using the override keyword. Polymorphism uses those methods to perform different tasks. It describes the concept that different classes can be used with the same interface. Here, it is important to understand the these divisions are specific to java. In the below example, you will find Java supports two kinds of polymorphism. Polymorphism is derived from 2 Greek words: poly and morphs. Following is the example of implementing a run time polymorphism in c# programming language. Polymorphism is used to remove the problem which is shown in the above code.It is done not by changing the name of the methods of both base & derived class.Infect it is done by adding the "virtual" keyword before the base class method, and the "override" keyword before the derived class method.As shown in this exmple: Poly meaning => many; morphism meaning forms; There are main two types of Polymorphism in PHP like as a. polymorphism in Compile time (function overloading) Polymorphism is the ability of an object to take on many forms. It refers to the use of a single type entity (method, operator or object) to represent different types in different scenarios. As mp3 player 4. As an example, assume there is a base class named Animals from which the subclasses Horse, Fish and Bird are derived. Real life example of polymorphism: A person at the same time can have different characteristic. The major purpose of C++ programming is to introduce the concept of object orientation to the C programming language. 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. Polymorphism uses those methods to perform different tasks. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. In c#, polymorphism provides an ability for the classes to implement different methods that are called through the same name and it also provides an ability to invoke the methods of a derived class through base class reference during runtime based on our requirements. Polymorphism is considered one of the important features of Object-Oriented Programming. Generally, the polymorphism is a combination of two words, one is poly and another one is morphs. Polymorphism provides the ability to a class to have multiple implementations with the same name. Or we can say that the same function name (but different signatures) being uses for different types of code. With Polymorphism, a message is sent to multiple class objects, and every object responds appropriately according to the properties of the class. Object-Oriented Programming (OOP) is commonly used to develop software. Static Polymorphism in JAVA: Static polymorphism is achieved through method overloading and is also known as compile time polymorphism or static binding. In simple words, polymorphism is the ability by which, we can create functions or reference variables which behaves differently in different programmatic context. Thus classes, methods, object are important concepts of OOPs. Then what does the term compile time “polymorphism” means?? It is one of the core principles of Object Oriented Programming after encapsulation and inheritance. Well, this is the only available support for operator overloading in java, and you can not have your own custom defined operator overloading in java. Also assume that the Animals class has a function named Move, which is inherited by all subclasses mentioned. “+” operator can be used to add two integers as well as concat two sub-strings. The mechanism of linking a function with an object during compile time is called early binding. We will learn about polymorphism in c# with an example and Type of polymorphism in c# in this article. Like we specified in the previous chapter; Inheritance lets us inherit attributes and methods from another class. Let's understand the polymorphism with examples. OOP contains four pillars such as Inheritance, Polymorphism, Abstraction and Encapsulation. The four basic concepts of OOP (Object Oriented Programming) are Inheritance, Abstraction, Polymorphism and Encapsulation.
