  @param string the string containing the unsigned {@code byte} representation to be parsed.
  @param radix the radix to use while parsing {@code string}
  @throws NumberFormatException if the string does not contain a valid unsigned {@code byte} with
  the given radix, or if {@code radix} is not between {@link Character#MIN_RADIX} and {@link

  @throws NullPointerException if {@code string} is null (in contrast to {@link
