    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.

    Key Concepts

    • Method Overriding
    • Method Overloading
    • Overriding vs Overloading
    • Tostring() Method
    • Recursion Concept
