The Future of Java is Today
summary
Java now ships concrete, demoed features: the launcher runs multiple source roots and the new compact source files remove the boilerplate main class while implicitly importing java.base types and exposing simple IO for quick read/write. Pattern matching deconstruction matches records and future deconstructors aim to split classes into components. Concurrency demos use virtual threads to handle many slow connections and a structured concurrency scope that joins tasks and surfaces failures at the join point. JDK24/25 previews are shown working in live demos.
