Object Oriented Programming (oops)

Object-Oriented programming is the technique to design software. Object-Oriented Programming is a pattern that provides many concepts like Inheritance, data binding, Polymorphism, etc. You may say Object-Oriented Programming is a methodology to design a program using classes and objects.

Object-Oriented Programming has some features which are helping to develop and design software given as bellow.

• Class
• Object
• Inheritance
• Polymorphism
• Abstraction
• Encapsulation

Class: Class is the collection of objects, you may say the class is the entity of objects where we specify types of variables that can exist in an object as well as methods to perform the operation.

Object:  Object is the instance of the class. According to Microsoft MSDN. An object is basically a block of memory that has been allocated and configured according to the blueprint. A program may create many objects of the same class. Objects are also called instances, and they can be stored in either a named variable or in an array or collection.

Inheritance: inheriting properties and behavior by a class from another class is known as inheritance. It provides code reusability.

Polymorphism: When a method shows different behavior in the different scenario is known as polymorphism. For Example, Method Over Loading and Method Over Ridding...

Abstraction: To hiding internal process and show only required information to the user is called abstraction.

Encapsulation: Wrapping up data, code, and method in a single unit are called encapsulation. Encapsulation is responsible for hiding data at code/programming level.
