Java 25 isn’t just playing catch-up with newer languages; it’s reinventing itself by integrating some of the best ideas. Inspired by Kotlin’s succinct data classes and Scala’s pattern matching, Java now has records and enhanced pattern matching to make code cleaner and more expressive. Taking cues from Go’s lightweight concurrency, it introduces virtual threads and structured concurrency for massively scalable, simpler parallel code. And thanks to a bit of Rust’s influence on safety, the new Foreign Function & Memory API makes calling native libraries both high-performance and safe.

No fluff, no marketing – just real code and use-cases: we’ll look at how these features reduce boilerplate, boost performance, and tame concurrency headaches in everyday Java development. By the end, you’ll see how an “old” language can learn new tricks that will make your life easier as a Java developer.
