I wasn’t as fast as Scott who took the exam two months ago (the day after it came out). I waited until I was done with “FIRST robotics season” and a vacation before thinking about taking the first half of the new Oracle Certified Professional: Java 11 Developer certification. I passed today with an 87%.I’ll be taking the second half in a number of months.

Jeanne vs Scott’s exam

A lot changed since Scott took the exam. I think he got a lot of experimental/unscored questions. The exam was still harder than the OCA 8. But it wasn’t insanely hard like he got. Key differences:

  • Scott had a lot of “pick 3 or 8” type questions. About 75% of the questions I got were pick one out of four or five choices. I got exactly 4 questions with seven choices. One was “pick 3 or 7” and three were “pick 1 of 7”. I got about 6 questions with 6 answers. Two were “pick 2 of 6” and the others were “pick 1 of 6”. I got about 12 “choose 2 or 5” questions.
  • I got 7 questions on modules. Which is what you’d expect statistically. Scott had a lot more but I think that was because the topic was new and Oracle was testing questions.

What is still harder

  • Overall, it is longer than the OCA 8. It took me 75 minutes to get through all the questions on the first pass. Then I spent 50 minutes reviewing (and memorizing). During that phase, I fixed one incorrect answer and changed a correct answer to an incorrect answer so it was a wash.
  • The scope is larger than the OCA 8 and the questions go deeper. This makes sense as this is a professional level exam.

What else was interesting?

  • The instructions say press control to cross out answers. This didn’t work. (I had this problem before so it might be my exam center.) – update: this worked on part 2, so it was probably just the mouse at my testing center
  • The exam results are supposed to be available within 30 minutes. I didn’t bring my phone to the exam center. When I got home, the email with the results was from “30” minutes ago. It took me a little over half an hour from when I ended the exam until I go home so he results were available fast!

How I studied

Even though I’m the author a study book, I find I still need to review. More so for part 2 of the exam, but it still helps for part 1 seeing the details.

  • Read our OCA 8 book
  • Re-read the basic parts of Manning’s Module System book. I was the tech development editor for this book and also helped with some of the finishing touches.
  • Do all questions in our OCA 8 book and K&B’s 8 book.
  • Do about half the questions in our Practice exam book for OCA 8 and the mock exam. (I ran out of time to do them all. This was mainly about practicing speed and confidence anyway. I do know the material.)
  • Did the official practice questions. (It would have been better if these were split between part 1 and part 2)

How to register for the OCA 8 or OCP 8 study guide online materials

Wiley/Sybex recently redid their website. One of our readers (and I), didn’t find it that intuitive how to register the book to gain access to the practice materials. Their tech support was excellent and now I know what to do!

It’s actually the same as the old procedure. I just had trouble finding the links

Step 1 – Get an access code

  • Go to the registration URL
  • Choose the OCA 8 or OCP 8 book from the pull down
  • Fill out the form. Note that you’ll need the book handy to answer one question about it. Don’t worry. The question will be something like “what is the caption of Figure 1.2” and not something that requires understanding the material

Step 2 – Get the access code.

Wait until you get an access code in your email. The instructions say it takes up to 24 hours, but I got it within 5 minutes.

Step 3 – Add code on the new test bank website

If you bought our OCA/OCP Practice Exam book, you already have an account on this site. If so:

  • Log in
  • Click redeem access code
  • Copy/paste the access code from the email

If not, sign up for an account now.

  • Go to the test bank site
  • Click create account
  • Copy/paste the access code from the email
  • Filll out the other fields

My Experience taking the new Java SE 11 Programmer I 1Z0-815 Exam

Update (11/05/2020): Read The 1Z0-819 Exam page to learn how you can easily our Java 11 Study Guides to prepare for Oracle’s 1Z0-819 Exam, as well as the 1Z0-817 Upgrade Exam.

One day after Oracle announced the new Oracle Certified Professional: Java 11 Developer certification, I decided to jump in and take the first of two exams! As an author of a best-selling Java certification series, how hard could it be I thought? In short… very! I did pass, but it was very different from what I imagined it would be.

Certification Changes

On the surface, the new Java 11 Programmer I (1Z0-815) and Java 11 Programmer II (1Z0-816) exams appear to be loosely based on the original OCA 8 (1Z0-808) and OCP 8 (1Z0-809) exams. I say loosely, because glancing at the objectives would lead you to believe they might be the same exams. They are decidedly not! More on that in a minute. One major change to the structure, though, is that the Oracle Certified Associate title no longer exists. Completing either exam does not grant you any certification title, and you must complete both Programmer I and Programmer II exams (in any order) to be an Oracle Certified Professional 11. There is also a single Java 11 OCP Upgrade (1Z0-817) exam for holders of a Java 6/7/8 OCP certification. Each of the three new exams are listed at $245 US. Unlike previous Java exams, there is no discounted beta exam, or beta exam of any kind, for the new Java SE 11 exams.

Neither Jeanne nor I have taken the Programmer II exam yet, so the rest of this post will be about my personal experience with the new Programmer I exam.

OCA 8 (1Z0-808) vs Java 11 Programmer I (1Z0-815): What’s the difference?

A LOT. I can’t emphasize this enough. The new Programmer I exam is significantly harder than the OCA 8 exam was. Questions are much more involved, much longer, and often require answering multi-part questions. For example, a question might have 8 answer choices and you need to select 3 completely independent answers. Process of elimination is crucial to finishing the exam. For example, in some cases it’s a lot easier to find the 5 choices that don’t compile than the 3 that do.

The new Java 11 Programmer I exam also includes a lot of topics that were previously only found on the OCP 8 exam. While you don’t need to know stand-alone topics like Concurrency, JDBC, and NIO.2 for this exam, you do need to know nearly everything there is to know about core Java topics like interfaces, generics, and Java operators. Jeanne and I noticed the new objectives appear to be a lot vaguer and broader than the previous objective set, meaning they can (and do) encompass a lot more than is explicitly listed in the objective titles. For example, == and equals() are no longer listed in the objectives, but don’t let that lull you into thinking for a second that you don’t need to know them to pass the exam!

Modules, modules, modules, Oh my!

The Java 11 Programmer I exam includes new topics like Project Jigsaw modules. Prior to taking the exam, I thought there going were only going to be a handful of questions on modules. Boy was I wrong! There were many questions on modules and the depth of them was honestly very surprising. You definitely need to memorize all module-related command line arguments to java/javac/jdeps/jmod, as well as knowing the long and short command-line flags. Just because modules is 1 of the 12 of the top-level exam objectives, don’t be fooled into thinking only 1/12 of the questions will be on modules! Understanding modules is vital to passing this exam!

OCA 8 (1Z0-808) vs Java 11 Programmer I (1Z0-815): What’s the same?

Excluding modules, the objectives are quite similar between the OCA 8 and Java 11 Programmer I exams, but that’s more likely to do more harm than good. Anyone going into this exam thinking this is just a Java 11 version of the OCA 8 exam will be in for a surprise.

So what is the Java 11 Programmer (1Z0-815) exam?

In a nutshell, it’s like they took the old OCA 8 exam, increased the difficulty of the questions by an order of magnitude until it was as hard as the old OCP 8 exam. Then, they updated the length of questions so that you had to answer 2-3 questions at once in a single question. Next, they greatly increased the depth of any topic on the previous exam. For example, previously you might have only needed to know 2-3 StringBuilder methods, whereas now you need to know nearly all of them. Finally, they filled the exam to the brim with Java module questions.

Of course, they also included other new Java 9/10/11 topics, like var and some string/array methods, but they pale in comparison with the changes in depth, difficultly, and new module topics.

“Can I use your OCA 8 book to study for the Java 11 Programmer I exam?”

As the sole source of preparation for the exam, definitely not. The OCA 8 exam was significantly easier and lighter than the new Java 11 Programmer I exam, and we wrote the questions and topics to match that particular exam. If you only study from our previous book, there is a good chance you might fail the exam.

That said, you could use our OCA 8 book, as well as the first half of our OCP 8 book as a starting points for studying for the new Java 11 Programmer I exam, but you will absolutely need to supplement it with education on the new topics, methods, and classes in Java 9/10/11, as well as in depth and hands on knowledge of modules. You should also expect the questions to be at least on the level of difficulty as the OCP exam.

“Hey Scott and Jeanne, is there a new Java 11 certification book coming?”

We get this question a lot, even before the objectives were announced. All I can say is, stay tuned for now!
