 Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. It enables a single interface to be used for entities of different types, promoting flexibility, extensibility, and code reuse. Polymorphism can be achieved through two main mechanisms: compile-time (or static) polymorphism and run-time (or dynamic) polymorphism.
