Methods:

public static IntStream intStream(Spliterator.OfInt spliterator,
                                  boolean parallel)

Creates a new sequential or parallel IntStream from a Spliterator.OfInt. 



public static IntStream intStream(Supplier<? extends Spliterator.OfInt> supplier,
                                  int characteristics,
                                  boolean parallel)

Creates a new sequential or parallel IntStream from a Supplier of Spliterator.OfInt . This method also specifies the characteristics of the supplied Spliterator.

See also Iterator vs Spliterator.

                .intStream(Arrays.spliterator(new int[]{1, 3, 6}), false);
        double sum = ds.sum();
        System.out.println(sum);
    }
