Java Language Futures
summary
Project Amber uses the six‑monthly release cadence and preview features to ship small, testable language slices that add up to records, sealed classes and pattern matching for data‑oriented programming: records are shallow immutable carrier classes, sealed hierarchies make ADTs explicit, and patterns deconstruct nested values. Planned pieces include deconstructors for non‑record classes, an instanceof statement and a reworked constructor prologue/epilogue model (pre‑super validation) that supports Valhalla goals and could let APIs like Future be modeled as pure data.
