Methods in java.util.stream with parameters of type Predicate
Modifier and Type	Method	Description
`boolean`	Stream.`allMatch(Predicate<? super T> predicate)`	Returns whether all elements of this stream match the provided predicate.
`boolean`	Stream.`anyMatch(Predicate<? super T> predicate)`	Returns whether any elements of this stream match the provided predicate.
`default Stream<T>`	Stream.`dropWhile(Predicate<? super T> predicate)`	Returns, if this stream is ordered, a stream consisting of the remaining elements of this stream after dropping the longest prefix of elements that match the given predicate.
`Stream<T>`	Stream.`filter(Predicate<? super T> predicate)`	Returns a stream consisting of the elements of this stream that match the given predicate.
`static <T,A,R> Collector<T,?,R>`	Collectors.`filtering(Predicate<? super T> predicate, Collector<? super T,A,R> downstream)`	Adapts a `Collector` to one accepting elements of the same type `T` by applying the predicate to each input element and only accumulating if the predicate returns `true`.
`static <T> Stream<T>`	Stream.`iterate(T seed, Predicate<? super T> hasNext, UnaryOperator<T> next)`	Returns a sequential ordered `Stream` produced by iterative application of the given `next` function to an initial element, conditioned on satisfying the given `hasNext` predicate.
