    - #### ConcatenatingIterator

          public ConcatenatingIterator​(java.util.Iterator<? extends E> first,
                                       java.util.function.Supplier<java.util.Iterator<? extends E>> second)

      Create an iterator that concatenates the results of two supplied iterator. The second iterator isn't created until it is actually needed.
      Parameters:
        `first` - the first iterator
        `second` - a function that can be called to supply the second iterator

          public E next()

      Get the next item in the sequence.
      Specified by:
        `next` in interface `java.util.Iterator<E>`
      Returns:
        the next Item. If there are no more items, return null.
