![]() If you have an attribute that is not visible from the outside of an object, and bundle it with methods that provide read or write access to it, then you can hide specific information and control access to the internal state of the object.Įncapsulation is referred to one of the following two notions.ġ) Data hiding: A language feature to restrict access to members of an object. The general idea of this mechanism is simple. This concept is also often used to hide the internal representation, or state, of an object from the outside. It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. It has a number of methods that are common the objects present within that class.Įncapsulation is one of the fundamental concepts in object-oriented programming (OOP). Different objects have different states or attributes, and behaviors.Ī class is a prototype that consists of objects in different states and with different behaviors. When combined with the concepts of the Encapsulation and Polymorphism, Abstraction gives more power to the Object oriented programming languages.Īn object is a real-world entity which is the basic unit of OOPs for example chair, cat, dog, etc. It helps to reduce the complexity and also improves the maintainability of the system. ![]() Data hiding ensures exclusive data access to class members and protects object integrity by preventing unintended or intended changes. ![]() Data hiding is a software development technique specifically used in object-oriented programming (OOP) to hide internal object details (data members).
