Recipe IDorg.openrewrite.java.migrate.util.UseListOfArtifactorg.openrewrite.recipe:rewrite-migrate-java

Prefer List.of(..) in Java 10 or higher. Two input shapes are recognised: - Anonymous-class initialization (new ArrayList<>() {{ add("a"); add("b"); }}), which is replaced wholesale with List.of("a", "b") (immutable result, matching the anonymous-class idiom's typical intent). - A new ArrayList<>() or new LinkedHashSet<>() declaration followed by a chain of target.add(..) statements, which is collapsed to new ArrayList<>(List.of(..)) or new LinkedHashSet<>(List.of(..)) (preserving both the mutable collection and its iteration order).
