Polymorphism in Java refers to the ability of an object to take different forms or appear in different types. In Java, polymorphism allows methods to be written that can be used by objects of different classes, as long as those classes are derived from the same superclass. This allows for code reusability and flexibility in programming. There are two types of polymorphism in Java: compile-time polymorphism (method overloading) and runtime polymorphism (method overriding).
