To encapsulate members of our class, we need to use certain access modifiers. Encapsulation separates the conceptual interface and an abstraction. This is achieved through the state (the private fields) and the behaviors (the public methods) of an object. The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. The concept refers to the grouping of data variables and methods. To prevent accidental change, an object’s variable can only be changed by an object’s method. For example, if a developer wants to use a dynamic link library to display date and time, he does not have to worry about the codes in the date and time class.

It means that all of the object's data is contained and hidden in the object and access to it is restricted to members of that class. These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. All Rights Reserved. While every method is an encapsulation, it’s also an abstraction.
