Java 25 (released September 2025) addresses the long-standing criticism of Java being too verbose. Two key JEPs are highlighted: JEP 512 introduces compact source files and instance main methods, relocating static IO methods to java.lang.IO for easier access, while JEP 513 enables flexible constructor bodies by allowing statements before super() or this() calls.
