- - ### Constructor Detail

    - #### IntegerSequence.Range

          public IntegerSequence.Range(int start,
                               int max,
                               int step)

      Creates a sequence \( a_i, i < 0 <= n \) where \( a_i = start + i * step \) and \( n \) is such that \( a_n <= max \) and \( a_{n+1} > max \).
      Parameters:
        `start` - First value of the range.
        `max` - Last value of the range that satisfies the above construction rule.
        `step` - Increment.

  - ### Method Detail

    - #### size

          public int size()

      Gets the number of elements contained in the range.
      Returns:
        the size of the range.

    - #### iterator

          public Iterator<Integer> iterator()

      Specified by:
        `iterator` in interface `Iterable<Integer>`
