My similar question got marked as duplicate, but here is the helper methods I’ve used to avoid some of the boilerplate: public static <T> Stream<T> stream(Iterable<T> in) { return StreamSupport.stream(in.spliterator(), false); } public static <T> Stream<T> parallelStream(Iterable<T> in) { return StreamSupport.stream(in.spliterator(), true); }
An Iterator is a simple representation of a series of elements that can be iterated over. eg: List<String> list = Arrays.asList(“Apple”, “Banana”, “Orange”); Iterator<String> i = list.iterator(); i.next(); i.forEachRemaining(System.out::println); #output Banana Orange A Spliterator can be used to split given element set into multiple sets so that we can perform some kind of operations/calculations on … Read more
I have to admit that I had difficulties too when I first tried to find out the actual meaning of the characteristics and had the feeling that their meaning was not clearly settled during the implementation phase of Java 8 and is used inconsistently for that reason. Consider Spliterator.IMMUTABLE: Characteristic value signifying that the element source … Read more
You should almost certainly never have to deal with Spliterator as a user; it should only be necessary if you’re writing Collection types yourself and also intending to optimize parallelized operations on them. For what it’s worth, a Spliterator is a way of operating over the elements of a collection in a way that it’s … Read more
