Polymorphism

Polymorphism refers to the ability of an object to take on multiple forms. In Java, polymorphism occurs when a reference variable can refer to objects of different subclasses. This allows methods to behave differently depending on the actual object being referred to. There are three main forms of polymorphism in Java: method overriding, abstract method implementation, and interface implementation. Polymorphism provides benefits like simplicity and extensibility by allowing code to interact generically with base types and subclasses without needing specific type details.
