Some notes about Java OCA 8 Programmer I Online Materials

[Mushfiq Mammadov]

“Braces” was forgotten in one of flashcard question answer:




It is written “Choose all that apply” in one of "Assessment Test" but the options are radio-button not checkbox.




The other note is that if we check options of questions and then unckeck all of them the answer is noted as “Wrong answers” not “Unanswered”.




This note was written in forum once by Shantanu Bhate . I practise with “Assessment Test” and bookmark some questions for review later, but I could not come back. “Previous Question” button exists in “Chapter Tests” but not exists “Assessment Test” and “Practice Exam(s)”. It would be good that create this button.

Generally I liked online materials very much. It is very useful, nice design and comfortable using. I haven’t tested “Practice Exam(s)” yet, I need to repeat everything again. After this I will come back practice exam test absolute.

Luckily you only need to select 1 correct answer in this exercise so the combo of "choose all that apply" and "radio buttons" does the trick (although it's inconsistent with similar questions)

Maybe I can't explain my opinion correctly. I mean that "Definition" section should be "The parentheses, braces, return statement, and semicolon" instead of "The parentheses, return statement, and semicolon". Because the example a->true shows that braces is optional. "Braces" is emphasized in the explanation of other lambda question.

Yeah, you already explained your opinion correctly the 1st time (and I understood what you meant immdiately). And you are correct! So my remark was totally not related to your opinion. It was nothing more than a stupid remark about the spaces (because spaces has already been many times a minor issue in mock questions).

(a) -> { return true; } // line1 (term)
a->true // line2 (definition)

No spaces anymore in line2, so those are optional (and should be mentioned) as well My apologies for not being more clear about my stupidness and having you to type your explanation twice!

Oh, sorry, Roel, I hadn't understood your post correctly when I wrote twice. Now it is clear, sorry again

I concur that braces is missing. And it is really weird that the radio button vs checkbox thing is wrong. i checked our submission materials and the type is correct there. I've noted both issues here so I remember to report them to Wiley. (I"ll do so in a couple weeks to see if more issues come in as it is easier to get these corrected in batches)

For the usability issues, can you report them to Wiley directly? I suspect they might be more likely to change it if more people bring it up. As you might imagine, I don't have any control of that as an author.

I will say that I'm glad my book came out now. Because the current online materials are a vast improvement over what Wiley used to use.

You write #9 as a number of question on errata page, but the order of questions are changed in every entry.

I will do it with great pleasure

That's indeed a very common problem. Maybe the class name should be added to "uniquely" identify the question. Or maybe each questions should have (and display) some kind of a unique identifier (like on the Enthuware mock exams, eg. enthuware.ocajp.i.v8.2.1465). I think that's a great way of uniquely identifying each question so it's easily to refer to if needed.

Interesting. I didn't realize they shuffled the assessment exam question order online. It's question #1 in the physical book so I've referenced that and added the class name. This should be a short term problem as I do intend to report it to Wiley.

The questions in the practice exams are shuffled as well...
