Quick Answer
Java 9+ stream features: takeWhile(predicate) takes elements while condition is true then stops. dropWhile(predicate) skips elements while condition is true then takes the rest. Stream.iterate(seed, hasNext, next) finite iterate with termination condition. Stream.ofNullable(value) returns empty stream for null. These fill gaps that required workarounds in Java 8.
Answer
Java 9+ adds ifPresentOrElse for Optional. Collectors.teeing for combining results. Factory methods like List.of(), Set.of(), Map.of(). Enhanced Stream.iterate() for bounded sequences.
