Unlock Java 25: Scoped Values, Compact Source Files, and New Constructor Model

Java 25 introduces a suite of language and runtime enhancements—including Scoped Values that replace ThreadLocal, compact source files that shrink boilerplate, a new constructor execution model, tighter object headers, Shenandoah generational GC, structured concurrency, basic‑type pattern matching, and Stable Values for lazy immutable fields—making Java development faster, safer, and more expressive.
