What is abstraction? What is the advantage of abstraction?
What will be an ideal response?
Abstraction refers to the hiding of the internal details of the object from the user. By hiding the internal details from the user, the user cannot inadvertently make changes to the object. Attributes and behaviors that are not hidden are exposed to the user. The idea behind abstraction is to expose to the user only those attributes and behaviors that are necessary to the object, and to hide everything else.
