Java polymorphism is a core concept in object-oriented programming that allows methods to perform differently based on the object's type. It encompasses method overloading and overriding, leveraging inheritance and interfaces to enable objects to be treated as instances of multiple types. This facilitates dynamic method dispatch, where the JVM determines the correct method at runtime, and ad hoc polymorphism, which allows methods to handle various argument types. Understanding polymorphism is key to creating extensible and maintainable Java applications.
