Keeping up with Java: Look at All These New Features!
summary
Overview of concrete changes: Java moves to six‑month releases, JDK 11 is the current LTS, and JDK 9+ adds the module system and removes legacy modules (CORBA, JAX‑WS), forcing some migrations; jlink builds application runtimes down to ~10 MB from ~350 MB; local type inference var reduces boilerplate; preview language features add switch expressions and text blocks; runtime work includes ZGC and Shenandoah experimental GCs plus the Epsilon benchmark GC, application class‑data sharing and single‑file java execution for quicker startup and simpler scripting.
