Object Oriented Programming (OOP) utilizes an alternate arrangement of programming language than old procedural programming dialects (C, Pascal, and so forth.). It is a methodology which is essentially centered on the way objects collaborate to convey and share the data. It changed the utilization of procedural oriented programming, where the attention was on the methodology of execution. The object oriented methodology brought another way, giving more significance to the items. There are four basic concepts which are to be emphasized. The first concept is that of an Object. It is the basic building block of any programming language. It represents the way you can describe anything in the programming world. The next is Class; a class in OOP is the principle body of any system. The classes frame the fundamental improvement unit of any system. Third factor is Inheritance, where we can create a new class known as derived class from the parent base class. This helps in reducing the time for coding and the derived class is error free. The last factor is Polymorphism, which means the capacity to ask for that the same operations be performed by an extensive variety of diverse sorts of things.
