The book by Hanumant said that wrapper classes are not on the exam, so why does this question expects you to know the Short constructor?

The problem with official exam objectives is that they are not always fine grained. For some topics they have mentioned class level details while for some topics, they have mentioned only broad level topic name.

Since, this is relatively a very new exam, it is not possible to know exactly how much detail the exam requires on a particular topic. That is why the book discusses wrappers but makes it clear that it is not on official exam objectives. Surgical cuts while discussing topic to keep strictly within requirements of the exam while not missing out anything is not really possible.

The mock exams do broaden the scope a little bit to make sure the student is not surprised in the exam. Yes, it does requires a little more effort but we believe it is better to study a little more than a little less because failure by one question will hurt a lot.

So, in general:

Exam Objectives < Book < Mock Exams

While the book might suggest that wrapper classes are not heavily emphasized, the exam often tests foundational Java concepts, which can include wrapper class constructors. It's always a good idea to review them, as they can appear in tricky questions or related contexts.

Even if wrapper classes aren’t directly emphasized, Java often involves implicit autoboxing, which automatically converts between primitives and wrapper types like Short. So, it might be expected that you understand how Java handles these conversions, even if wrapper classes aren’t a major focus of the exam.

That's a good observation. While wrapper class constructors like Short may not be heavily emphasized, it's still useful to be familiar with them because they can appear in questions that test general Java understanding, even if indirectly. Enthuware sometimes includes such edge-case questions to ensure a broader conceptual grasp, so it’s worth reviewing key aspects of wrapper classes just in case.
