Is it possible to merge iterators in Java?

Question

Is it possible to merge iterators in Java? I have two iterators and I want to combine/merge them so that I could iterate though their elements in one go (in same loop) rathe

Answer 1

You can try ConcatIterator from Cactoos:

Iterator names = new ConcatIterator<>(
  Arrays.asList("Sarah", "Mary").iterator(),
  Arrays.asList("Jeff", "Johnny").iterator(),
);

Also check ConcatIterable, which concatenates Iterables.
