Question

Which keyword is used to control access to fields and methods from other classes?

a. public
b. protected
c. private
d. all of the above

Answer 1

Keywords that control access to class members in programming include public, protected, and private; hence, the correct answer is d. all of the above.

Step-by-step explanation:

The keyword used to control access to fields and methods from other classes are public, protected, and private. Thus, the correct answer to the question is d. all of the above. These access modifiers determine the visibility of a class and its members. For instance, members marked as public are accessible from any other class, whereas private members are accessible only within the class in which they are declared. Protected members are accessible within their own package or subclasses. Knowing how to use these keywords properly is essential for the implementation of encapsulation in object-oriented programming, which helps in maintaining the integrity of data.
