Explanation of Solution
“No”, there is no need to mention the actions of a class in the problem domain description.
Problem domain description:
Problem domain comes as the first step in finding out the classes.
- Problem domain is the set of real world instance or events that are related to a problem is called as problem domain.
 - Problem domain can be written only by an expert.
- One can write the explanation of the problem domain on their own, by analyzing and understanding the nature of the problem.
 - On the other hand, if the nature of the problem is not clearly analyzed, then a person needs an expert to write the problem description.
 
 
Class’s responsibilities:
After the identification of potential classes, the next step is to identify the class’s responsibilities...
