Question
You are developing finance and operations apps. using the X++ development language. You have created a class and you want to add a method to it.
You want to add a method that can only be called from methods within the same class and can’t be overridden in a subclass.
You need to add an accessor keyword to that method.
Which should you use?
Select only one answer.
A. static
B. private
C. public
D. protected
Answer
B. private
Explanation
The ‘private’ keyword allows a method to be called only from methods within the same class and can’t be overridden in a subclass. ‘public’ methods can be called from anywhere the class is accessible and can be overridden by a subclass. ‘protected’ methods can only be called from methods in the same class or methods in a subclass of that class. ‘static’ is not an accessor keyword, it’s used to declare a method that belongs to a class, not an instance of the class.
