Methods:

public static <T> Stream<T> stream(Spliterator<T> spliterator,
                                   boolean parallel)

Creates a new sequential or parallel Stream from a Spliterator. 



public static <T> Stream<T> stream(Supplier<? extends Spliterator<T>> supplier,
                                   int characteristics,
                                   boolean parallel)

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