Polymorphism is one of the core concepts of object-oriented programming (OOP) that allows objects of different types to be treated as instances of the same class through inheritance. It means "many shapes" and refers to the ability of a single interface or function to operate on different types of objects, allowing for flexible and scalable code.
There are two main types of polymorphism:
Compile-time polymorphism (Static polymorphism): Achieved using method overloading and operator overloading, where multiple methods or operators share the same name but differ in parameters (number, type, or both). The decision of which method to call is made at compile time.
Example: Method Overloading in C#
Runtime polymorphism (Dynamic polymorphism): Achieved using method overriding, where a subclass can provide a specific implementation of a method that is already defined in its superclass. The method to be executed is determined at runtime based on the object's actual type.
Example: Method Overriding in C#
