I just noticed that the football-match-reports concept exercise expects the student to throw an IllegalArgumentException in one of its tasks, while the exceptions concept isn’t unlocked at that time yet. Adding exceptions as a prerequisite isn’t possible, because this would introduce a circular dependency between the football-match-reports and calculator-conundrum exercises.
I see two possible ways to resolve this:
- Remove the use of exceptions from the
football-match-reportsexercise - Remove the use of switch statements from the
calculator-conundrumexercise
Which option to choose IMO depends on the syllabus design: which concept should be introduced first to a user, exceptions or switch statements?
