It’s been a long time since JDK 9 went GA. That new release of Java is packed with some powerful features like modules, API enhancements like factory methods for an immutable list, set, and map, some changes on Stream API and Optional class, new features on Process API, etc.
Since it’s always good to keep yourself up-to-date, its time to spend some time to learn those new features and make use of them to write better code in Java.
When it comes to learning a new technology or a new thing, online courses work best. They help you to get going quickly by providing the essential stuff and encourage you to learn more.
Books are also good but you learn quickly using online courses than books because they focus on the most important parts and doesn’t provide in-depth coverage as the book does.
In my opinion, you should read a book after finishing a course to further cement the concepts and fill the gaps, as more often books provide more comprehensive coverage.
