Why Get Certified in Java 11, aren’t there newer versions available?
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, 12, 13, 14, 15, etc all of which are no longer supported by Oracle.
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, etc. This is by design. Because Java 11 is Oracle’s long term supported version of Java. For this reason, Java 11 is the version of Java you need to become certified in. And this course will help you achieve that.
Do I really need to take a “Java exam course” to pass the exam?
Being completely upfront, it is possible to pass the exam without studying a specific exam course like this one. But it’s not easy. Keep in mind that the exam does not just test your knowledge of Java, but actively tries to trip you up by asking questions that sometimes use obscure, rarely used syntax that you may never have come across before. The sorts of things that most Java courses or textbooks will never teach you.
This course shows you all the standard Java stuff you need to know, as well as this more obscure stuff to ensure you really are ready to pass the exam.
