Builder	builder() Returns a builder for a DoubleStream .
R	collect(Supplier supplier, ObjDoubleConsumer accumulator, BiConsumer combiner) Performs a mutable reduction operation on the elements of this stream.
DoubleStream	concat(DoubleStream a, DoubleStream b) Creates a lazily concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream.
long	count() Returns the count of elements in this stream.
DoubleStream	distinct() Returns a stream consisting of the distinct elements of this stream.
DoubleStream	empty() Returns an empty sequential DoubleStream .
DoubleStream	filter(DoublePredicate predicate) Returns a stream consisting of the elements of this stream that match the given predicate.
OptionalDouble	findAny() Returns an OptionalDouble describing some element of the stream, or an empty OptionalDouble if the stream is empty.
OptionalDouble	findFirst() Returns an OptionalDouble describing the first element of this stream, or an empty OptionalDouble if the stream is empty.
DoubleStream	flatMap(DoubleFunction mapper) Returns a stream consisting of the results of replacing each element of this stream with the contents of a mapped stream produced by applying the provided mapping function to each element.
void	forEach(DoubleConsumer action) Performs an action for each element of this stream.
void	forEachOrdered(DoubleConsumer action) Performs an action for each element of this stream, guaranteeing that each element is processed in encounter order for streams that have a defined encounter order.
DoubleStream	generate(DoubleSupplier s) Returns an infinite sequential unordered stream where each element is generated by the provided DoubleSupplier .
DoubleStream	iterate(final double seed, final DoubleUnaryOperator f) Returns an infinite sequential ordered DoubleStream produced by iterative application of a function f to an initial element seed , producing a Stream consisting of seed , f(seed) , f(f(seed)) , etc.
PrimitiveIterator.OfDouble	iterator()
DoubleStream	limit(long maxSize) Returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
DoubleStream	map(DoubleUnaryOperator mapper) Returns a stream consisting of the results of applying the given function to the elements of this stream.
IntStream	mapToInt(DoubleToIntFunction mapper) Returns an IntStream consisting of the results of applying the given function to the elements of this stream.

DoubleStream	of(double t) Returns a sequential DoubleStream containing a single element.
DoubleStream	of(double... values) Returns a sequential ordered stream whose elements are the specified values.
DoubleStream	parallel()
double	reduce(double identity, DoubleBinaryOperator op) Performs a reduction on the elements of this stream, using the provided identity value and an associative accumulation function, and returns the reduced value.
OptionalDouble	reduce(DoubleBinaryOperator op) Performs a reduction on the elements of this stream, using an associative accumulation function, and returns an OptionalDouble describing the reduced value, if any.
DoubleStream	sequential()
DoubleStream	skip(long n) Returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream.
DoubleStream	sorted() Returns a stream consisting of the elements of this stream in sorted order.
Spliterator.OfDouble	spliterator()
double	sum() Returns the sum of elements in this stream.
DoubleSummaryStatistics	summaryStatistics() Returns a DoubleSummaryStatistics describing various summary data about the elements of this stream.
double[]	toArray() Returns an array containing the elements of this stream.
