It's also worth noting that a new version of the IntStream.iterate has been added since Java 9: WebIt is best suited for applications in which set sizes generally stay small, read-only operations vastly outnumber mutative operations, and you need to prevent interference among threads during traversal. It is thread-safe. Mutative operations ( add, set, remove, etc.) are expensive since they usually entail copying the entire underlying array.
