Java 25 Tutorial

Java 25 (released September 16, 2025) is a Long-Term Support (LTS) version of the JDK, bringing 18 new JEPs and enhancements. It focuses on developer productivity (e.g., compact source files/instance main methods) and cleaner syntax. It also boosts performance via features like compact object headers, ahead-of-time method profiling, and improvements to the garbage collector. Java 25 further advances modularity (module import declarations) and scoped values, making concurrent and modular coding more expressive. As an LTS release, it is intended for broad adoption over the coming years, offering stability along with these innovations.
