I agree with Jeanne, I think you're overthinking the question.  If you're trying to hang the computer, a simple while loop will suffice:

For #2, it's guaranteed because the question says it is enough time.  The question text isn't asking you if 100ms is enough time, it's telling you it is.
Thanks!  I've confirmed the errata and updated the book pages:

Appreciate you finding these so we can make sure they don't make it into our upcoming Java 17 book!
First off, congratulations on passing the exam and thrilled we could help!

Unfortunately, no, Oracle does not mail certifies (or pins) like they used to (or Sun used).  In Oracle's CertView page you can navigate to eCertificate and print a certificate yourself.  I find the digital badges to be more useful, though, since they can be shared/verified with employers directly.
I think you've got time. While they won't keep it around forever, I suspect they won't take it down before September.

I noticed that on your website (https://www.selikoff.net/ocp11-1/) you used page 83 instead of 81 for this errata.

Kind regards,
Michael



Oh, sorry.  It's page 81 in the 1Z0-815 book, page 83 in the CSG.
That's an edge case I often don't often think of, but yes it is unclear.

I believe this is the only binary operator to have right-to-left associativity.  All other binary operators are left-to-right.
Depends how much experience you have to start with.  It’s not a lot of time but for $25, it’s not a lot to lose either!
Oracle announced a big discount today for Java's 25th Anniversary.  If you're feeling up to it, you can take it again in the next 2 months for only $25:

Don't forget to get a study guide too.  The Practice Test book is great for preparing for the exam, but you need a study guide to learn the material and the reason  behind it!
Java 11 has some really great features, so I'd recommend it.  It also saves you time from having to get certified in the future for the newer version.
I don't think this is the Japanese version, that would be 1Z0-819-JPN (following their 815/816 naming).  My guess is this is just the English version with the "J" meant to denote Java's 25th anniversary.  PearsonVue lists both the 1Z0-819 ($245) and 1Z0-819-J ($25) so my guess is they just listed this exam twice with different prices.
The modules objectives covers a lot of topics, so there's no short list of things you need to study.  We wrote two chapters in our study guide to cover this, so that's a great place to start if you haven't worked with modules before.
