Chapter 4.
I thought I knew everything, in fact, I thought most of it could be answered from what I knew before/outside of Java.
If the questions are realistic, I can see that they could take the longest of any questions on the test and be voted most likely to be skipped if short on time!

Anyway, we aren't supposed to be approaching the book as novice programmers or even novice Java users, but I still think there is a high percentage of tricky stuff in the end of chapter questions that isn't covered until later chapters, at least chapter 5.  For one thing, Arrays and ArrayLists abound in all their glory in the Chapter 4 questions.

But why I am posting this is that when I put together the test to take online, intending to have practice in a somewhat similar format to the actual test, Question 20 from the book (one of the easier ones!) showed no code snippet at all, just the answers.  I was ready to guess "Lorne Michaels", "Abraham Lincoln" or "Tunisia".

I think I saw some comment saying that the book authors don't really have direct control of the supplementary materials including the test questions, but that was frustrating.

Another oddity that I noticed, on all the tests I tried so far, running in a standard, up-to-date Google Chrome browser on Windows 10, is that pieces of "code font" embedded in answers render way smaller than the surrounding text.

Something like
The answer is unreadable due to this phenomenon.

I don't know if you indeed have any control at all over that, but I didn't think it was due to odd browser or computer configuration on my part and I already got at least one, probably at least two wrong answers in the first 4 end-of-chapters (and a few on the Assessment if I recall correctly) due to that weirdness.  In the future I will break out the magnify tool before plunging into the darkness.

I have an engineering degree from an all-scholarship school that was painfully difficult, and I've played some really hard games, but if the sample problems accurately reflect difficulty of 815 questions, the test is pretty hard!  Sure, if you could take all day on them, but from what I've heard you can't afford to dawdle on the 819....hmmm...

Anyway, thanks for a great book.  I felt several questions were only readily answerable using information not yet found in the text by the end of Chapter 4, but mostly you just need to really work fast and keep a clear head.  Thanks again.

In the same vein as the original post (comment/complaint/question)
I notice that in the Publisher's Online Test Bank for what is Question 12 in the print book for Chapter 6
the blank that is supposed to be in front of the first line is not rendered.
That rendered me very confused, and I left out an answer that was appropriate.
Strangely enough, the auto-grader marked me correct despite omitting the additional answer that I would have checked if that blank had shown.

I don't know if you even have any control over that content, but thought it meet to mention here.
The text looked something like:
Question 19  tb584704.JaSE11PrgISG.c06.12
Which pieces of code can fill in the blanks? (Choose all that apply.)

first = () -> Set.of(1.23);
_________________ second = x -> true;

As tricky as the questions were, I thought it was just some kind of a trick, but since I got marked correctly anyway, I will consider it a treat.

We don't have any control over the font/rendering in the online test bank. Further, Sybex changes the online engine periodically which makes it hard to optimize for it.
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
