Applications of  OOP OOP is one of the programming buzzword. There appears to be a great deal of excitement and interest among software engineers in using OOP. Applications of OOP are beginning to gain in many importance areas. The most popular application of objection-oriented programming ,up now ,has been in the area of user inter-  face design such as windows. There are hundreds of windowing systems developed using OOP techniques    . Real-business system are often much more of complex and contains are more object in   with complicated attributes and method . OOP is useful in this type of  applications of   because of can simplify a complex.  The areas for application of OOP . Real-time systems . Simulation and modelling . Object-Oriented database .

 The Features of Java OOP (Object-Oriented Programming) are the key principles that make Java a   features object-oriented language.              Classes:- A class is a user define data type date contain data member and member function .A class is a group of similar type object that same have properties common be haviour and common relationship Objects:-  Object is instance of a class or real time entity of a class In OOP program is divided into number of object. it is a variable of a class object is an instance of class. Syntax:- Class-name, Object- name   Abstraction:- The  process of hiding is complex implementation in details and showing only the essential features to the user. Abstraction means providing only the essential details to the outside world and hiding the internal details    Encapsulation:- The building of data  attributes and the methods operate on that data within a single (a class).
