I submitted a post regarding one of the SCJA mock exam questionshere within the SCJA certification topic. Is it possible that this is an error/ambiguity on the mock exam?
If not, please could someone explain when it is appropriate to use italics for abstract methods/objects in UML, when it is necessary, and when it is not?
This is just because I do not want to find that I have been marked incorrect in another mock exam ( or worse, real exam ) for the assumption that the use of italics is optional, especially if the correct answer were to use the italization as the justification as to why myanswer is marked incorrect.
Italics is not optional. If it is italicized, it is indeed abstract.
One of the problems is that many UML diagrams are so small and convoluted, it's sometimes difficult to tell if letters have been italicized or not. I'm not saying this applies to your mock exam question, but more, to UML diagrams in general.
Good luck on your exam! If you need more help on SCJA, check out my ExamScam certification guide.
