Fundamentals of Cloud Computing Through abstraction, we can hide unwanted data. Encapsulation is an implementation level process, and it is used to provide privacy and maintain control over the transparency of data at the implementation stage of a project. We have several capabilities in a vehicle, such as a drive(), stop(), setSpeed(number), and so on, that let us control the car while driving. How many times a GATE exam is conducted in a year? : It becomes quite difficult to operate the program if all of the member functions and data members are interconnected throughout the program. When you modify your code implemented with an abstraction, the abstractions users need not modify their code. Encapsulation is hiding the data and controlling the visibility of the code. 2) Abstraction means we are hiding internal implementation details. On the other hand encapsulation is about hiding internal details? This is a general answer not related to a specific programming language (as was the question). You may gather some details that are irrelevant when developing a banking application. Java It is also used to hide the complex details and provide the simpler interface to the user. Walked through the examples of abstraction, and encapsulation. Abstraction represents only useful data, whereas encapsulation wraps data and codes for necessary information. That data and code will be accessed outside the method/member function and the class that is not the members of that class.
