OOP means Object Oriented Programming. It organizes a program around its data,i.e.,objects and a set of well defined interfaces to that data.An object-oriented program can be characterized as data controlling access to code.This is a technique used to create programs around the real world entities. In OOPs programming model, programs are developed around objects and data rather than actions and logics. In OOPs, every real life object has properties and behavior. This feature is achieved in java through the class and object creation. They contains properties (variables of some type) and behavior (methods). OOPs provides better flexibility and compatibility for developing large applications.
