The next item from the stream in Scala

Question

Is there any way or way to get each next element from the stream?

For example, if there is a stream similar to

def natural: Stream[Long] = { def naturalHelper: Long => Stream[Long] = { n => n #:: naturalHelper(n+1) } naturalHelper(1) } val s = natural 

I am looking for something like s.next() , returning 2 on the first call, s.next () = 3 on the next call, etc .... without using var .

Answer 1

Make Iterator

 val s = natural.iterator s.next() s.next()
