As of 1st Aug 2019, this article has now been outdated.
It is has been only a few months since the new Java 11 OCA/OCP certification 1Z0-815, 1Z0-816, and 1Z0-817 exams have been released. We have been getting questions every day about how to prepare for these exams. We would like to answer them in this article. Before we get into the details, you must know that Oracle has actually scrapped the OCA level certification for Java 11.

Earlier, Oracle used to run beta versions of the Java OCA/OCP exams for several months before releasing the final version. This gave a lot of time to authors to create study material for these exams. This time, however, Oracle released the production versions these exams without any notice or without releasing the beta versions. That is why there are no books to prepare for these exams in the market as of 14th April 2019. But you can use chapters 1 to 19 (except chapter 13 on I/O) of Herbert Schildt's Java: The Complete Reference, Eleventh Edition to prepare for Java 11 part 1 certification exam.

We mentioned in an earlier write up about our experience on the OCP Java 11 Part 1 1Z0-815 exam, that this exam is similar to the OCA Java 8 exam in terms of toughness but there are several changes in the exam. So, using existing OCA Java 8 exam study books and mock exams to prepare for the new OCP Java 11 certification exam will be very dangerous.

Note that Oracle allows candidates who have passed the OCA Java 8 exam (1Z0-808) to take the OCP Java 11 Part 2 exam (1Z0-816). So, if you don't have access to any other book or resource, it would be better to take the OCA Java 8 (1Z0-808) exam and then take the OCP Java 11 part 2 exam (1Z0-816) later.

If you still want prepare for the 1Z0-815 exam using a book for 1Z0-808, here are the steps:

  1. See the comparison of exams objectives for 1Z0-808 and 1Z0-815 first. Make a note of the topics that have been added (most notably Modularization and var declarations) and of the topics that have been removed (most notably the Date/Time API).

  2. Go through a book for the OCA 8 exam such as this or this.

  3. OCP 11 part 1 (1Z0-815) exam is a little more advanced than the OCA 8 (1Z0-808) exam on overriding of methods with respect to generics. So read up on how generics affect the return type in overriding of methods. Try this book for reading up on Generics.

  4. Read about modularization topic from online tutorials. You may also go through Chapters 1 to 6 of this book.

  5. Read about new features of added in Java 9, 10, and 11. You can google them. There are several online articles about them. You need to focus on the following topics:
    1. Modularization
    2. Local variable type inference (var declarations)
    3. New methods in String/StringBuilder
    4. New methods in Arrays class - compare/mismatch
    5. New methods in Collections API (Set.of/List.of)
    6. Functional interfaces - Supplier, Consumer, Function, Predicate

  6. Finally, use Enthuware's 1Z0-815 Mock Exams to see how well you are prepared for the real exam and to plug any holes in your knowledge about the topics that are on the exam. Start with the first Standard mock exam and see how you score. Make sure you go through the explanations (even for the questions you answer correctly) because we include a lot of important tips in the explanations. Read up on the topics on which you scored less from any online resource before taking the next test. Your goal should be to increase your score with each mock test. If you are able to pass any of the standard mock exams in first attempt, you should be good to go for the real exam!
