Recap


                          Object-oriented programming is a programming paradigm that focuses on objects instead of
                         routines or functions.
                         An object is a real-world entity like car, dog, pencil and computer.
                         A class can be defined as a user defined blueprint or prototype that is used to create objects.
                         Data abstraction refers to a process of hiding the complex or unnecessary data and show only
                         the data essential for the user.
                         Encapsulation refers to a process of binding data and function together into a single unit like
                         a capsule.
                         Inheritance allows a class to acquire or inherit all the properties and behaviors from its parent
                         class.
                         The term polymorphism is made up of two words “poly" and “morph" which means many forms.
