After Eight Sweet New Features in Java
summary
Covers concrete changes since JDK 8 through JDK 14: the module system splits rt.jar into 75 modules and jlink -> ~10MB runtime for minimal container images; some deprecated items start to be removed (six methods in JDK 9); JDK 10 adds var local type inference and experimental Gra JIT plus G1 parallel full-GC and application class data sharing; JDK 11 adds single-file source launch, standardized HTTP/2 client, and removes CORBA/JAXB/JAX‑WS modules; JDK 12 previews switch expressions (later using yield); JDK 13 previews text blocks; JDK 14 previews records and pattern matching and shows the helpful NullPointerException.
