Spliterators

A Java Spliterator interface (also known as a splittable iterator) is an interface that's used to traverse the elements of a source (for example, a collection or stream) in parallel. This interface defines the following methods:

public interface Spliterator<T> {  boolean tryAdvance(Consumer<? super T> action);  Spliterator<T> trySplit();  long estimateSize();  int characteristics();}

Let's consider a simple list of 10 integers:

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

We can obtain a Spliterator interface for this list like so:

Spliterator<Integer> s1 = numbers.spliterator();

We can also do the same from a stream:

Spliterator<Integer> s1 = numbers.stream().spliterator();

In order to advance to (traverse) ...
