In Java Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects.OOPs, can also be characterized as data controlling for accessing the code. In this approach, programmers define the data type of a data structure and the operations that are applied to the data structure.
Before Object Oriented Programming (commonly referred as OOP), programs were written in procedural language.the OOP is all about creating objects that can interact with each other, this makes it easier to develop programs in OOP as we can understand the relationship between them.OOP is a way to structure a program using reusable pieces of code (called classes) which can be used to create individual instances of objects.
