  • Method Details

    • min

      public int min()
      Return the minimum value of the integer range.
      Returns:
      the minimum value of the integer range

    • max

      public int max()
      Return the maximum value of the integer range.
      Returns:
      the maximum value of the integer range

    • size

      public int size()
      Return the size of the IntRange: max - min.
      Returns:
      the size of the int range
      Since:
      3.9

    • stream

      public IntStream stream()
      Returns a sequential ordered IntStream from min() (inclusive) to max() (exclusive) by an incremental step of 1.

      An equivalent sequence of increasing values can be produced sequentially using a for loop as follows:

      for (int i = range.min(); i < range.max(); ++i) { ... }
      Returns:
      a sequential IntStream for the range of int elements

    • of

      public static IntRange of(int min, int max)
      Create a new IntRange object with the given min and max values.
      Parameters:
      min - the lower bound of the integer range
      max - the upper bound of the integer range
      Returns:
      a new IntRange object
      Throws:
      IllegalArgumentException - if min > max

    • of

      public static IntRange of(int value)
      Return a new (half open) range, which contains only the given value: [value, value + 1).
      Parameters:
      value - the value of the created (half open) integer range
      Returns:
      a new (half open) range, which contains only the given value
