Class IntStepIterator

  • All Implemented Interfaces:
    IntIterator

    public class IntStepIterator
    extends java.lang.Object
    implements IntIterator
    An iterator over a sequence of integers with regular steps, e.g. 2, 4, 6, 8...

      Constructor Description
      IntStepIterator​(int start, int step, int limit)
      Create an iterator over a sequence with regular steps
    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      boolean hasNext()
      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.
      int next()
      Return the next integer in the sequence.

      • IntStepIterator

        public IntStepIterator​(int start,
                               int step,
                               int limit)
        Create an iterator over a sequence with regular steps
        Parameters:
        start - the first value to be returned
        step - the difference between successive values (must be non-zero)
        limit - if step>0, the iteration will not deliver any values greater than this limit; if step<0 the iteration will not deliver any values lower than this limit

      • 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()
        Description copied from interface: IntIterator
        Return the next integer in the sequence. The result is undefined unless #hasNext() has been called and has returned true.
        Specified by:
        next in interface IntIterator
        Returns:
        the next integer in the sequence
