Method

boolean	allMatch(Predicate predicate) Returns whether all elements of this stream match the provided predicate.
boolean	anyMatch(Predicate predicate) Returns whether any elements of this stream match the provided predicate.
Builder	builder() Returns a builder for a Stream .
void	close() Closes this stream, causing all close handlers for this stream pipeline to be called.
R	collect(Collector collector) Performs a mutable reduction operation on the elements of this stream using a Collector .
R	collect(Supplier supplier, BiConsumer accumulator, BiConsumer combiner) Performs a mutable reduction operation on the elements of this stream.
Stream	concat(Stream a, Stream 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.
Stream	distinct() Returns a stream consisting of the distinct elements (according to Object#equals(Object) ) of this stream.
Stream	empty() Returns an empty sequential Stream .
Stream	filter(Predicate predicate) Returns a stream consisting of the elements of this stream that match the given predicate.
Optional	findAny() Returns an Optional describing some element of the stream, or an empty Optional if the stream is empty.
Optional	findFirst() Returns an Optional describing the first element of this stream, or an empty Optional if the stream is empty.
Stream	flatMap(Function> 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(Consumer action) Performs an action for each element of this stream.
void	forEachOrdered(Consumer action) Performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order.
Stream	generate(Supplier s) Returns an infinite sequential unordered stream where each element is generated by the provided Supplier .
Stream	iterate(final T seed, final UnaryOperator f) Returns an infinite sequential ordered Stream 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.
Iterator	iterator() Returns an iterator for the elements of this stream.
Stream	limit(long maxSize) Returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
Stream	map(Function mapper) Returns a stream consisting of the results of applying the given function to the elements of this stream.
Optional	max(Comparator comparator) Returns the maximum element of this stream according to the provided Comparator .
boolean	noneMatch(Predicate predicate) Returns whether no elements of this stream match the provided predicate.
Stream	of(T t) Returns a sequential Stream containing a single element.
Stream	of(T... values) Returns a sequential ordered stream whose elements are the specified values.
S	onClose(Runnable closeHandler) Returns an equivalent stream with an additional close handler.
S	parallel() Returns an equivalent stream that is parallel.
Stream	peek(Consumer action) Returns a stream consisting of the elements of this stream, additionally performing the provided action on each element as elements are consumed from the resulting stream.
T	reduce(T identity, BinaryOperator accumulator) Performs a reduction on the elements of this stream, using the provided identity value and an associative accumulation function, and returns the reduced value.
Optional	reduce(BinaryOperator accumulator) Performs a reduction on the elements of this stream, using an associative accumulation function, and returns an Optional describing the reduced value, if any.
Stream	skip(long n) Returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream.
Stream	sorted(Comparator comparator) Returns a stream consisting of the elements of this stream, sorted according to the provided Comparator .
Stream	sorted() Returns a stream consisting of the elements of this stream, sorted according to natural order.
Spliterator	spliterator() Returns a spliterator for the elements of this stream.
Object[]	toArray() Returns an array containing the elements of this stream.
A[]	toArray(IntFunction generator) Returns an array containing the elements of this stream, using the provided generator function to allocate the returned array, as well as any additional arrays that might be required for a partitioned execution or for resizing.
