Constructor Details
- ConcatenatingIntIterator
  
  public ConcatenatingIntIterator(IntIterator first, Supplier<IntIterator> 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
Method Details
- hasNext
  
  public boolean hasNext()
  
  Description copied from interface: IntIterator
  
  Test whether there are any more integers in the sequence; and change the state of the iterator so a call on IntIterator.next() delivers the next integer.
  The effect of calling #hasNext() a second time without an intervening call on #next() is undefined.
  
  Specified by:
  
  hasNext in interface IntIterator
  
  Returns:
  
  true if there are more integers to come
- next
  
  public int next()
  
  Get the next item in the sequence.
  
  Specified by:
  
  next in interface IntIterator
  
  Returns:
  
  the next Item. If there are no more items, return null.
