What is Polymorphism? Difference between Runtime and static Polymorphism with the help of a program.

Question

Accepted Answer

Polymorphism is the ability of an object to take on many forms. Runtime polymorphism is achieved through method overriding.

Polymorphism allows objects of different classes to be treated as objects of a common superclass.
Static polymorphism is achieved through method overloading.
Runtime polymorphism is determined at runtime based on the actual type of the object.
Static polymorphism is determined at compile-time based on the number and types of arguments passed to a method.
Example of runtime polymorphism: Animal class with a method 'makeSound' overridden in subclasses like Dog and Cat.
Example of static polymorphism: Calculator class with multiple methods named 'add' that accept different numbers of arguments.
