Java 16 Is Coming!
summary
Java 16 finalizes pattern matching for instanceof so code can write an instanceof Type name that checks and declares the variable in one step and pattern variables no longer must be effectively final. Records become official: single-line type declarations that auto-generate a canonical constructor, accessors (no get prefix), equals, hashCode and toString, with components final and no extra fields. Sealed types (preview) let a type list permitted subtypes so the compiler enforces exhaustiveness and replaces many visitor patterns. Multi-release JARs and the HTTP/2 reactive client are also part of the release.
