summary

Java moves faster with a six‑month cadence and actually ships concrete syntax and behavior: JDK 12 adds switch expressions (preview -> yield in JDK13) that return values and remove fall‑through; JDK13 adds text blocks for multiline strings; JDK14 introduces preview records plus compact constructors and pattern‑matching for instanceof; JDK15 adds sealed classes and local records; by JDK16 records and pattern matching become standard while sealed classes enter a second preview.
