So let us begin by answering the burning question, what is Encapsulation?

To put it simply, encapsulation is the process of surrounding an object with other components in order to conceal its internal details from users.

There are several examples of encapsulation in Java. This concept is easily demonstrated using the class keyword. This keyword enables programmers to create their own custom classes that contain a collection of data and methods used by their programs. These classes can be thought of as belonging to a separate "layer" that only the class's creator has access to.
