Encapsulation is a data-hiding technique that helps to control the access of the data. It's a programming concept that makes it possible for developers to create objects and then access the properties and methods of object without exposing these to other objects.
Java is a programming language that is used to create applications, games, websites and other software. This language has a lot of features, but it also has some unique ones. One of these unique features is encapsulation.
Encapsulation allows you to change code that has already been implemented without breaking other code. It protects the data and programmes from outside inheritance. As a result, encapsulation aids in the attainment of security.
Encapsulation of member variables. All data members should be defined as Private members of the Class in Object-Oriented Programming.
Encapsulation of functions. Private functions used just for internal API implementation must always be specified.
Encapsulation of classes.
Abstraction is a technique for concealing undesired information. Encapsulation, on the other hand, is a way of hiding data in a single entity or unit as well as a method of protecting information from the outside.
