How to create a Java 8 Stream from an iterator?

Question

Is it possible to create a Stream from an Iterator, in which the sequence of objects is the same as that generated by calling the iterator\'s next() method repeatedly? The s

Answer 1

This doesn't create a stream, but Iterator also has a method called forEachRemaining:

someIterator.forEachRemaining(System.out::println);
someIterator.forEachRemaining(s -> s.doSomething());
//etc.

The argument you pass in is a Consumer which is the same thing you pass to Stream::forEach.

Here are the docs for that method. note that you can't continue the "chain" like you can with a stream. But I've still found this helpful the few times I've wanted a Stream from an Iterator.
