The two years release cadence of LTS versions gives the entire Java ecosystem the opportunity to accelerate. It also brings the new features Java has to offer faster, so that developers can improve applications readability, maintainability as well as development productivity.
This presentation covers three of the new features of the JDK: Amber, Loom and Valhalla. Amber is about bringing pattern matching to the Java language. It's currently added bit by bit: records, pattern matching for instanceof, for switch, and record pattern matching. Loom offers a new concurrent programming model. With Loom, you can write your code in a synchronous way, without any callback, and execute it asynchronously, with all the performances benefits you may expect. It is a preview feature of the JDK 19. Valhalla brings a new kind of objects to the language, so that you do not have to choose between performances and abstraction.
