    - #### URISyntaxException

          public URISyntaxException(String input,
                            String reason,
                            int index)

      Constructs an instance from the given input string, reason, and error index.
      Parameters:
        `input` - The input string
        `reason` - A string explaining why the input could not be parsed
        `index` - The index at which the parse error occurred, or `-1` if the index is not known
      Throws:
        `NullPointerException` - If either the input or reason strings are `null`
        `IllegalArgumentException` - If the error index is less than `-1`

    - #### URISyntaxException

          public URISyntaxException(String input,
                            String reason)

      Constructs an instance from the given input string and reason. The resulting object will have an error index of `-1`.
      Parameters:
        `input` - The input string
        `reason` - A string explaining why the input could not be parsed
      Throws:
        `NullPointerException` - If either the input or reason strings are `null`

  - ### Method Detail

    - #### getInput

          public String getInput()

      Returns the input string.
      Returns:
        The input string

    - #### getReason

          public String getReason()

      Returns a string explaining why the input string could not be parsed.
      Returns:
        The reason string

    - #### getIndex

      Returns an index into the input string of the position at which the parse error occurred, or `-1` if this position is not known.
      Returns:
        The error index

    - #### getMessage

          public String getMessage()

      Returns a string describing the parse error. The resulting string consists of the reason string followed by a colon character (`':'`), a space, and the input string.
