Question
Why access control is required?
Solution
Access control is a security technique that regulates who or what can view or use resources in a computing environment.
It is a fundamental concept in security that minimizes risk to the object. In other words, access control is a selective restriction of access to data.
In Object-oriented programming languages, it is implemented through access modifies.
Classical object-oriented languages, such as C++ and Java, control the access to class members by the public, private, and protected keywords.
