Late Binding

Late binding, also known as dynamic binding, is a programming concept where the method or function to be executed is determined at runtime rather than compile time. It allows for greater flexibility in object-oriented programming by enabling polymorphism, where objects of different types can be treated uniformly through a common interface. This is commonly implemented using virtual methods in languages like C++ or dynamic dispatch in languages like Python and Java.

Also known as: Dynamic Binding, Dynamic Dispatch, Runtime Binding, Virtual Method Invocation, Dynamic Linking

Why learn Late Binding?

Developers should learn and use late binding when building systems that require runtime flexibility, such as in plugin architectures, dependency injection frameworks, or when implementing design patterns like Strategy or Observer. It is essential for enabling polymorphism in object-oriented programming, allowing code to work with objects of various types without knowing their exact class at compile time, which enhances maintainability and extensibility in large-scale applications.
