Question

What concept within object-oriented programming involves the restriction of the manipulation of an object's state by external users to a set of method calls?

Answer 1

Answer:

The concept of data encapsulation within object-oriented programming involves the restriction of the manipulation of an object’s state by external users.

Explanation:

• In the discipline of object-oriented programming, objects are nothing else but repositories of data existing in the form of fields.
• Through data encapsulation, the vulnerable data is literally capsulated so that the object’s state cannot be manipulated by any agent working externally.
• Hence, data encapsulation can be referred to as a secure procedure of safeguarding the objects (data repositories).
