To Java 18 and Beyond!
summary
Survey of concrete changes since Java 11: JEP 378 adds text blocks (triple quotes) so multiline JSON no longer needs escapes; JEP 361 makes switch an expression with arrow syntax and yield; JEP 394 brings pattern matching for instanceof; JEP 395 adds records as compact immutable data classes; JEP 409 adds sealed classes to limit subtypes; ZGC delivers sub-millisecond pauses (~100 µs typical); AppCDS and the simple jwebserver speed startup (startup often drops ~1s); security manager and finalizers are deprecated for removal.
