OOPs revolve around the four concepts:
In OOPs, these concepts are implemented through a class definition and achieved through the object creation process, programmatically.
Here we will discuss Encapsulation briefly:
-- Encapsulation is an important programming concept.
-- It helps in separating the states of an object from its behavior.
-- It plays a vital role in maintaining security in the code by hiding the object's data (describing its state) from any unwanted external modifications.
-- Java provides the access rights to the external entities through the four different access modifiers, these are public, private, protected and default.
-- Encapsulation allows the object being used within an application to know about the data according to the user's requirement.
-- Unwanted data that is not required by an object is kept hidden by the process of encapsulation. It is also known as information hiding.
-- Information hiding restricts the outsiders in seeing inside an object and thus providing security.
