    • validateInteger

      public abstract boolean validateInteger​(int i)
      Checks whether or not an int value is valid.

      return (i > 0);

      Parameters:
      i - the int value to check
      Returns:
      true when the specified int value is accepted, false otherwise

      A subclass must override this method, thereby specifying its own acceptable range for the double value. For example, to accept only strictly positive numbers, the following code can be used:

      return (d > 0.0);

      Parameters:
      d - the double value to check
      Returns:
      true when the specified double value is accepted, false otherwise
