How to determine the level of access of the elements of a class?

Question

This is a question of the Secitec 2018 competition for the position of computer teacher. I appealed to this question because there are no qualifiers, but access modifiers such as: private, protected and public. The reserved word "package" is not an explicit access modifier according to Deitel & Deitel. What alternative in this case would be the correct one? Then the question follows.

Encapsulation is one of the basic principles used in object-oriented programming, which makes it possible to restrict access to variables and methods a class. To determine the access level of elements of a class are used qualifiers, two of them are characterized below.

(I) It is the most rigid level at which only the methods of the own class have access to variables and other methods.

(II) Is the level at which variables and methods can be accessed only by other classes belonging to to the same package.

The qualifiers (I) and (II) are called, respectively:

A) public and package

B) public and protected

C) private and package

D) private and protected

Answer 1

Depending on the interpretation of the examiner’s bench may be alternative C or question reversed. In fact, the term package does not apply to the access modifier but to the access level (package-protected, or package-level protected). The fact of calling qualifier modifier is subject to the interpretation of the bench, because it is possible to understand one another, although the usual term is modifier.
