This talk is a follow-up to my talk "New language features in Java since JDK11". In that talk, I walked you through all the awesome new stuff. Today I’ll show you actual usages of these new features so that you can start using them in your project too. Come and see real-world usage for constructs like records, switch functions, sealed classes, and pattern matching to name a few. This is even more important if you consider that the upcoming releases of extremely popular and widely used frameworks such as Spring (v6) and Spring-Boot (v3) will use JDK17 as the minimum baseline for development. Don't get left behind and let me show you how to use all the new language features from JDK11 up to JDK17 in these frameworks.
