This article provides a detailed, code-focused overview of the key features in Java 25. It covers language and syntax upgrades like flexible constructor bodies, primitive patterns, and compact source files. It also explores new concurrency tools (Scoped Values, Structured Concurrency), security APIs (KDF, PEM), profiling enhancements (JFR), and startup optimizations (AOT cache).
