1Z0–819 : Passed in 2021. How to clear New Java OCP 11 Developer exam step by step guide
Oracle has announced a new exam, the 1Z0–819 taking effect 1st October 2020. This new exam takes the content from the 1Z0–815 exam as well as the 1Z0–816 exam and combines them into one exam. This is good for you as you only need to sit one exam to become Java certified.1Z0–819 exam would be a combination of topics covered in the two exams.
Java 11 is designated as the LTS or Long Term Support version of Java — it’s going to be supported by Oracle and JDK vendors until at least 2026, unlike Java 9, Java 10, and Java 12, all of which are no longer supported by Oracle. Even Java 13’s support will cease in March 2020.

Large companies have large codebases, and it takes them a long time to upgrade that code to new versions of Java — for years Java 8 was the main version used by companies and with the release of Java 11, and Oracle’s commitment to supporting it for many years as well as them designating it as the long term support version, this means that the majority of the industry will be moving, or already have moved to Java 11. Particularly now that Java 8 support is ending soon.
Oracle does not have a certification program for Java 9, 10, 12, or Java 13. This is by design. Because Java 11 is Oracle’s long term supported version of Java. For this reason, Java 11 its the version of Java you need to become certified in. And this course will help you achieve that.
As a matter of fact, the new 1Z0–819 exam would be a combination of topics covered in the two exams. So, candidates who have been preparing for 1Z0–815 and 1Z0–816 exams could easily pursue one single certification to become Oracle Certified Java SE11 Developer. Therefore, the 1Z0–819 certification basically simplifies the path for aspiring Java SE11 Developers.
The duration of exam is 90 Minutes and Number of Questions asked is50. The Passing Score is 68%.
