Runtime Polymorphism
Runtime polymorphism is a core object-oriented programming (OOP) concept where the specific method or function to be executed is determined at runtime, based on the actual type of the object rather than its declared type. It enables dynamic method dispatch, allowing a single interface to represent different underlying forms (polymorphism) and facilitating code flexibility and extensibility. This is commonly implemented through mechanisms like method overriding in inheritance hierarchies or interfaces.
Developers should learn runtime polymorphism to build scalable and maintainable software systems, as it supports the design of flexible architectures where behavior can be extended without modifying existing code. It is essential in scenarios requiring dynamic behavior, such as plugin systems, GUI frameworks, or game engines where objects of different types need to be handled uniformly. By decoupling interface from implementation, it enhances code reusability and adheres to principles like the Open/Closed Principle in SOLID design.
