Question

How can a protected modifier be accessed?

(a) accessible only within the class

(b) accessible only within package

(c) accessible within package and outside the package but through inheritance only

(d) accessible by all

This question was addressed to me in a job interview.

I would like to ask this question from Access Control in section Classes and Methods of Java

Answer 1

The correct choice is (c) accessible within package and outside the package but through inheritance only

To explain I would say: The protected access modifier is accessible within package and outside the package but only through inheritance. The protected access modifier can be used with data member, method and constructor. It cannot be applied in the class.
