Complete Study Guide (Sybex, 2020), which we happen to be the authors of, to start in your studies. This book is also available as two separate volumes if you prefer to carry around a paper book: OCP Java SE 11 Programmer I Study Guide (Sybex, 2019) and OCP Java SE 11 Programmer II Study Guide (Sybex, 2020). Whether you purchase the Complete Guide, or the Programmer I and Programmer II books, the material is the same and will properly prepare you for the exams.
Regardless of which study guide you used to prepare, you can use this book to hone your skills, since it is based on topics on the actual exams.
Unlike the questions in our study guides, which are designed to be harder than the real exam, the questions in this book mirror the exam format. All the questions in this book tell you how many answers are correct. They will say “Choose two” or “Choose three” if more than one answer is correct.
Choosing an Exam
If you don't hold any previous Java certifications, then you should take the 1Z0‐819 Java SE 11 Developer Exam. It is a very broad exam, covering subjects from basic Java concepts and syntax to more advanced topics and APIs. Some libraries you may use every day, while others you may not be familiar with in your career, such as the concurrency, annotations, and NIO.2 APIs. The exam also includes a lot of topics around the new Java module platform.
If you already hold a recent Java Professional certification, then you are eligible to take the upgrade exam. Table I.1 lists who is able to take each exam. This book will help you prepare for both the 1Z0‐819 Exam and the 1Z0‐817 Upgrade Exam.
TABLE I.1 Java 11 Professional Certification Exams
| Exam Code | Name | Who Should Take |
|---|---|---|
| 1Z0‐819 | Java SE 11 Developer | Everyone can take this exam. |
| 1Z0‐817 | Upgrade OCP Java 6, 7, & 8 to Java SE 11 Developer | Holders of any of the following:Sun Certified Programmer for the Java Platform, SE 6 (SCJP6)Oracle Certified Professional, Java SE 6 Programmer (OCJP6)Oracle Certified Professional, Java SE 7 Programmer (OCJP7)Oracle Certified Professional, Java SE 8 Programmer (OCJP8) |
What Happened to the 1Z0‐815 and 1Z0‐816 Exams?
When Oracle released the Java 11 certification in March 2019, it was originally obtained by taking two exams: the Programmer I 1Z0‐815 Exam, which focused on core Java structures, and the Programmer II 1Z0‐816 Exam, which focused on broad topics and APIs.
In October 2020, Oracle retired these two exams and replaced them with a combined 1Z0‐819 Exam. The authors of this book were instrumental in working directly with Oracle to ensure the new exam did not introduce a lot of new material that was not on the previous two exams.
We mentioned this in case you pick up one of our Java 11 Study Guides and notice the 1Z0‐815 or 1Z0‐816 Exam titles on the cover. Don't panic! These books can definitely be used for the 1Z0‐819 exam! The material is nearly identical. Please visit our blog for more details:

The 1Z0‐819 Exam
The 1Z0‐819 Exam is a 90‐minute exam with 50 questions and requires a passing score of 68 percent. For those who may be familiar with the previous Java 7 and 8 certifications exams, the 1Z0‐819 Exam combines material from what was previously two exams into a much broader exam with fewer questions. This means that each question may cover a variety of objectives and the time you have on each question is more constrained.
To study for the 1Z0‐819 Exam, we recommend a study plan that uses our OCP Oracle Certified Professional Java SE 11 Developer Complete Study Guide along with this book. As mentioned, this book is available in two parts if you prefer an easier to carry around option, OCP Java SE 11 Programmer I Study Guide and OCP Java SE 11 Programmer II Study Guide.
We also recommend reading our blog about some of the changes made to the 1Z0‐819 Exam after these study guides were published.

The 1Z0‐817 Upgrade Exam
The 1Z0‐817 Upgrade Exam is a 180‐minute exam with 80 questions and requires a passing score of 61 percent. It is designed for those who already hold a Java 6 or higher Sun or Oracle Professional Certification. Those with only Java Associate certification titles or older Java certifications are not eligible for this exam.
For the 1Z0‐817 Upgrade Exam, we recommend a study plan that uses either our OCP Oracle Certified Professional Java SE 11 Developer Complete Study Guide or OCP Oracle Certified Professional Java SE 11 Programmer II Study Guide, along with this book.
While either our Complete Study Guide or Programmer II Study Guide will help you pass the exam and make you a better programmer, you do not need to read the entire book. Table I.2 lists the chapters that will prepare you for the 1Z0‐817 Upgrade Exam.
TABLE I.2 Study Guide Chapters for the 1Z0‐817 Upgrade Exam
| Book | Chapters To Review |
|---|---|
| Java 11 Complete Study Guide | 2, 6, 11, 12, 14, 15, 16, 17, 18, 20 |
| Java 11 Programmer II Study Guide | 1, 3, 4, 5, 6, 7, 9, Appendix |
You can still use the practice exams in Chapters 14, 15, and 16 of this book to prepare for the 1Z0‐817 Upgrade Exam. You can just skip any questions on the topics that are not on the upgrade exam and calculate your score with the remaining questions.
Which Exam Should I Take?
If you hold an eligible certification title, you are free to take either the 1Z0‐819 Exam or the 1Z0‐817 Upgrade Exam. Which you take is completely up to you. Having taken both, we tend to believe the 1Z0‐817 Upgrade Exam is less challenging, in part because the number of topics is not nearly as broad as the 1Z0‐819 Exam. You also have more time to read each question on the exam.
