Java Language update
summary
Six‑month cadence forces features into smaller increments and preview is production quality so feedback matters; records are immutable data carriers and records go through the canonical constructor which changes Java serialization; sealed interfaces plus pattern matching and upgraded switch provide compiler exhaustiveness checking and deconstruction patterns; example ADT “async return” models four outcomes (success failure timeout interruption) replacing checked exceptions; jshell and a simpler entrypoint aim to make small programs and exploration practical.
