# Record Patterns Use for **Record Patterns** work from [JEP 440](https://openjdk.org/jeps/440) when targeting JDK 21+. ## When active - Replace `instanceof R r` plus accessor calls with `R(...)` record patterns. - Use nested record patterns for record graphs. - Use `var` component patterns when explicit component types add noise. ## Pitfalls - Record patterns match records only and do not match `null`. - Every record component position needs a pattern. - Generic record patterns infer type arguments; ordinary type patterns do not. ## Examples Read `examples/jep-440.md` for JEP-derived snippets. ## References - https://openjdk.org/jeps/440 - https://openjdk.org/jeps/441
