Wow, I didn't expect this.

I've just taken the exam but fortunately I have a friend who's now preparing for it so this book will be greatly appreciated! 😊

Once again, thank you Jeanne and thank you Scott! Your study guide has been life saving.

Happy to know that our material was helpful in your preparation



Thank you, everyone!

I finally did it - today I passed the Java 11 OCP exam with 87%.

It was a long journey, it all started almost a year ago (9-10 months more precisely). I wanted to take on the old 1Z0-815 and 1Z0-816 exams, like everyone else. I was prepared to take the first one like 6 months ago, but hours before my appointment a techical failure happened at the test center and they had to cancel it. I was very very lucky, because the same day I learned about the new exam, 1Z0-819. I was happy to find out that the exam lasts just 90 minutes now instead of 180 for the old one. The bad part was that 1Z0-819 includes double the study material in a quarter of the time.

So how was it, you ask? Well, it was a lot to take in. Lots and lots of methods to memorize, corner cases, classes - but hard work pays off I guess. I am working a full time job so I was familiar with some of the concepts, but I had to learn lots of others. I studied in the afternoon - at first I was't doing it every day but then it became routine.

I want to thank Jeanne Boyarsky and Scott Selikoff. Really, thank you. Your study guides have been excellent. I started with the 1Z0-815 guide then went all in with the complete study guide which came later. The book covers like 95% of the exam and everything is explained clearly and concisely.

I was ready to take the first exam when the new one came out, so I didn't insist on the first part of the complete study guide. I started reading the second part - I was doing a chapter per week (includong the quiz at the end of each chapter). As I was reading alone, I noted down some  takeways for each section. Upon finishing the book, I had around 150 pages written by hand (it's easier for me to learn new stuff like that - it helps me memorize).

After finishing the book I went ahead and read my own notes until I was comfortable with all material. I had to read everything 4 times.

In the meantime I got the Enthuware model exams and started doing one a day in the weeks before the exam. If you want to be prepared for the exam, buy the Enthuware mock exams - trust me, it's worth it. They have been life saving.

As I was doing the mock exams I started noting down all the mistakes I've made which also helped me a lot. The days before the exam I went through those. My average score in the Enthuware exams was 81% and I was pretty happy and confident about the real exam.

And now the exam day: well, even of I was pretty confident I was also very nervous. I've chosen taking the exam at a test center near me - I think it really helps you get in the mood, avoiding getting too comfortable at home.

It turned out the mock exams were way closer to the real thing than I initially thought! The difference was that there were a lot of questions with lots of code to go through - I was pretty scared seeing them because they were the most time consuming.

My main advice would be to practice your time management skills. I finished the exam with 4 minutes to go, which is...well, close. Considering the lengthy questions, be careful. I had 15 minutes to go and 10 more questions to solve so I had to rush it in the end, but it turned out well. The questions were not overly complicated besides that - if you read the material thoroughly and do the mock exams you'll be fine.

I had a lot of questions about generics, functional interfaces (& lambdas) and streams. Understand these very well, they're critical. I also had some questions on modules but they were fine.

In the end I'm happy that I took the exam and I'm happy that I can finally take a break.

Phew, this was a long post, but I hope it helps!
Yeah, it looks ridiculous to me as well, but in the same time it's an opportunity to learn about things that we don't use that much on our jobs, like you said.

I have the feeling that 1Z0-815 is a walk in the park compared to 1Z0-816...

Oh, and by the way - you may want to rush your learning because 1Z0-816 is being retired since 1st of October. You might also consider going for 1Z0-819 directly (this is also what I am doing).
Well, I definitely recommend the books by Scott Selikoff and Jeanne Boyarsky. You might want to read the article HERE where Scott explains how to tackle the exam. I think the study guide is the best option, so if you get that book you should be fine. I will be doing that as well. As for mock exams, I think there is also a practice guide for 1Z0-819 on the way, but I am not sure. Until then, you can combine 1Z0-815 and 1Z0-816 mocks to prepare for 1Z0-819.
As I've mentioned earlier to another rancher, the introduction of var (makes use of the local type inference) with Java 10 and also the new module system (with the associated command line options), introduced with Java 11 are the biggest changes compared to Java 8. You can also declare private methods in interfaces starting with Java 9. In the same thread Scott also mentioned the new of() methods in certain APIs (like collections, NIO/2) the single-file source-code programs and others.

Scott Selikoff wrote:It's available now.  You can sign up to take the exam today with appointments (for me) as early as 9/21.  I expect Oracle to post the remaining exam details soon, but I would expect it to have less questions given the shorter time.

Also, having taken the 815/816 exams, 3 hours was kind of overkill for me.  Granted I didn't need a lot of time, but in most cases I finished in about an hour.



I was also doing a mock exam in one and a half to 2 hours. Luckily I did not take the 1Z0-815 yet...I am going to prepare for 1Z0-819 directly, this is why I am curious about the exam details. Personally, I am expecting around 50 questions...

  • I'm taking the 819 on 9/26. That will give me a feel for how hard it is



  • I think everyone's curious about that. Can't wait to read about your experience.

    Yes. We were just about done with the 815/16 practice book. Since it hadn't gone to print, we pulled it back and are restructuring it for for the 819. That will come with 3 mock exams for the 819.



    That sounds great! Thank you! I'll be getting this one, as I'm gonna take 1Z0-819 directly (skipping 1Z0-815).
    Hi everyone.

    When should we expect more details about the new 1Z0-819 exam? I am mostly interested in the number of questions and also the passing score. The official exam page doesn't say much for now...

    And also, when is the actual exam going to be available? I am very curious about how it is to take the actual exam compared to the soon retired ones.

    I think we're not going to see anything until the 1st of October, but it doesn't hurt to ask...

    Thanks!

    Jeanne Boyarsky wrote:Adrian,
    The mock exams are online. Just pretend the 815 is an easy mock exam and the816 is a challenging mock exam.



    Hmm, okay. So we must use the existing ones. That's alright. Do you have a 1Z0-819 Practice book in sight? That would be awesome. The one for the Java 8 exam was great and it helped me even when preparing for 1Z0-815.

    Jeanne Boyarsky wrote:Ron,
    Our complete study guide is geared for the 8198; it just doesn't say so on the cover . The 819 is the 815/816 with a few objectives removed. The book will prepare you very well.



    Hi, Jeanne. I am mostly concerned about the mock exams...will you include some mock exams for 1Z0-819? Ho should we prepare for it besides reading the book? What do you recommend?

    Pooja Kaul wrote:I was preparing for 1Z0-815. Now got to know 1Z0-815 & 1Z0-816 merged together into 1Z0-819. I welcome this decision of Oracle because after giving 1Z0-815, I could have definitely gone lazy to give 1Z0-816. Now I will be forced to learn whole core till advanced java.
    Secondly, the cost of the fee is reduced and its really useful for students like me. Who is not working and have to pay fee on their own pocket. But yes 90 minutes, that means time management needs to be worked strongly.

    All the best to everyone and also to me for 1Z0-819



    Yes, I agree here. Even though I had an appointment for 1Z0-815 I am quite pleased now with the fact that I have to take a single exam now instead of two. I was going to take the 1Z0-816 anyway (next year). Yeah, this stuff delays the exam with a few months because now I have to study for the second part, but I am quite optimistic. I am somewhat lucky because I work with some of these concepts on a daily basis so it should be easier to study for those. I'll get Scott and Jeanne's book for 1Z0-816 and get cracking!

    Jeanne Boyarsky wrote:Adrian,
    The 819 is cumulative. You still need to know the material on the 815. (Well except for the very easiest stuff, but I bet you didn't spend a long time deciding it was platform independent)



    Well, it is what it is I guess. I know half the stuff needed to pass 1Z0-819, that's the good news. I'll skip 1Z0-815 because there's no way to get fully certified until 1st of October and just fully focus on the new exam. Are you guys planning to release a whole new study guide for 1Z0-819 or are we good with the ones for 1Z0-815 and 1Z0-816?
