Introduction. Object Oriented Programming has been the best way to write programs in any language.But why OOP technique?As a matter of fact our physical world is made up of objects with different qualities.OOP is based on the concept of “objects” which can contain data or code.
A good example can be an animal object with several properties like movement,sound,diet,life span etc.We can also talk about a “bank object” , which I will be considering in this post, with properties like customers,accounts and methods like accounts creation,loan repayments etc.
