Data hiding and data encapsulation are usually regarded as the same thing by a computer novice. Data hiding and data encapsulation involve objects, classes, structures, computer code, and methods.
Data encapsulation is the process of assembling elements to create a new entity and also the wrapping of private data into a class. Data encapsulation is one of the mechanisms for hiding data. In data encapsulation, the capsule and the object inside it can be classified as either private or public.
Data hiding can be defined as the process of hiding the details of objects. It is a good way of programming result in data security and less data complexity. Data hiding is used as a method of hiding information inside a computer code after the is broken down. Data hiding is usually used on executed on volatile and sensitive data.
Data hiding, otherwise known as abstraction, and encapsulation are both basic oriented programming—concepts that allow you to apply real-world objects into programs and codes. Abstraction is a fundamental OOP concept which focuses on just the pertinent data of an object and hides the background details and highlights the essential points to reduce complexity and increase efficiency. Abstraction concentrates on ideas rather than events.
The resulting object can also be called abstraction. Encapsulation, on the other hand, is another OOP concept which connects data and functions into a single component while impeding access to some components. It is one of the main underlying concepts of OOP which covers information under a single unit. In simple terms, encapsulation means hiding attributes to shield variables from outside contact so that switch in one part of a function won’t affect other parts. It provides basic integrity to the data by safeguarding it from the outside world.
Data hiding and Data encapsulation are the two major concepts when it comes to object-oriented programming. Data hiding And Data encapsulation both involve objects (which are classified as data, functions, values, or structures), classes (collection of methods and data), methods, and the computer code. However, data encapsulation simply refers to the process of assembling and combining elements so as to create a new entity, and also wrap private data into a class. This encapsulation simply involves the implementation of methods and data.
Encapsulation also has to do with the way it hides the class from users and also reverses the process by using the methods to unlock the capsule. On the other side of the coin, data hiding simply refers to the process of hiding an object's or function's details. This technique helps to achieve less data complexity and security in programming. It can also be used to hide information in a computer code.
