- Q2. What are the types of polymorphism in Object-Oriented Programming?
- Ans.
Types of polymorphism in OOP include compile-time (method overloading) and runtime (method overriding) polymorphism.
Compile-time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.
Runtime polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already defined in its superclass.
Polymor...
