Java Language Futures - Mid 2020 Edition
summary
JDK 15 ships with preview and final language pieces: records as nominal tuples let you declare just the data header and get final fields, accessors, equals/hashCode/toString, plus compact canonical constructors and static nested records; pattern matching for instanceof eliminates repetitive casts and enables deconstruction patterns that pair cleanly with records and future type-aware switch cases; sealed classes (preview) let a type list its permitted subtypes so the compiler can do exhaustiveness checks; these features are previewed and require explicit enablement.
