      In addition to this book, Scott and Jeanne are also the authors of the following best‐selling Java 11 certification books: OCP Java SE 11 Programmer I Study Guide (Sybex, 2019), OCP Java SE 11 Programmer II Study Guide (Sybex, 2020), and Java SE 11 Developer Complete Study Guide (Sybex, 2020). They also wrote the three best‐selling Java 8 certification books.

      This book is intended for those who want become a Java 11 Oracle Certified Professional (OCP) by taking either the 1Z0‐819 Exam or the 1Z0‐817 Upgrade Exam, as well as those who want to test their knowledge of Java 11. If you are new to Java 11, we strongly recommend you start with a study guide to learn all of the facets of the language and come back to this book once you are thinking of taking the exam.

      We recommend the best‐selling OCP Java SE 11 Developer 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.

      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.

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.
