1 year ago How can we have a solution with separate Instructor and Coordinator classes while avoiding this problem?
Good question @kyueran
The answer will be given during this week's lecture.
Hint: we use the Person class to represent the actual person (i.e., only one object per person) and Instructor, Coordinator classes to represent the roles played by that person (i.e., one object for each module taught by that person).
May I ask in the first screenshot it says there can be a solution with a separate Instructor and Coordinator class. But from the second screenshot it shows that if we have two separate classes we face the problem of having duplicate person as a coordinator and instructor (Tom in this case) which is not allowed. How can we have a solution with separate Instructor and Coordinator classes while avoiding this problem?
