Returns a possibly parallel Stream with this collection as its
source. It is allowable for this method to return a sequential stream.
This method should be overridden when the spliterator()
method cannot return a spliterator that is IMMUTABLE,
CONCURRENT, or late-binding. (See spliterator()
for details.)
Stream over the elements in this
collection
@implSpec
