Study Notes
Object-Oriented Programming (OOP) Introduction
- By the end of this lecture, students will be able to understand Polymorphism, Method Overriding, Method Overloading, Overriding vs Overloading, and the Tostring() Method.
Polymorphism
- Polymorphism is a Greek word, meaning "one name many forms" or "many forms of one name".
- It means one object has multiple forms or has one name with multiple functionalities.
- "Poly" means many and "morph" means forms.
- Polymorphism provides the ability for a class to have multiple implementations with the same name.
- It is one of the core principles of Object-Oriented Programming, along with encapsulation and inheritance.
