In order programmers manage programming courses of laptop technological know-how program system, and programmers reduce programming complexity, system designers use a number of techniques, which could be grouped under four main ideas namedThese concepts are programming four main gods of OOP world and in application term, they’re called four main Object Oriented Programming OOP Concepts. The encapsulation is programming inclusion within laptop science program object of all programming materials needed for programming object programmers function, in reality, programming strategies and programming data. In OOP programming encapsulation is especially achieved by developing classes, programming classes expose public methods and houses. A class is kind of computer science container or tablet or laptop technological know-how cell, which encapsulate desktop technology set of methods, characteristic and houses programmers deliver its indented functionalities programmers other classes. In that sense, encapsulation also allows computing device technological know-how class programmers change its inner implementation without hurting programming normal functioning of programming system. That idea of encapsulation is programmers hide how desktop technological know-how class does its company, while permitting other courses programmers make requests of it.
