It seems like keeping up to date with Java nowadays is an enormous task. Gone is the era of big, delayed Java releases that span years. We're now getting a new major release every six months. What's up with that? You're probably still developing on Java 8, even though Java 12 is already available.
Join this session to get a code-first overview of what's new in Java since Java 8. We'll give an overview of the module system (Java 9), the local-variable type inference feature (Java 10), the new HttpClient API (Java 11) and a sneak peek of Switch Expressions in Java 12. Expect lots of advice on what to expect when migrating beyond Java 8. It's time to embrace the newfound agility of the Java platform!
