Drop while a predicate returns true

Starting with JDK 9, we also have the Stream.dropWhile​(Predicate<? super T> predicate) method. This method is the opposite of takeWhile(). Instead of taking elements until the given predicate returns false, this method drops the elements until the given element returns false and includes the rest of the elements in the returned stream:

• If the stream is ordered, it returns a stream consisting of the remaining elements of this stream after dropping the longest prefix of elements that match the given predicate.
• If the stream is unordered, and some (but not all) of the elements of this stream match the given predicate, then the behavior of this operation is nondeterministic; it is free to drop any subset ...
