code: public static String setLength( String original,
                                      int length,
                                      char padChar ) {

      }
docs: Set the length of the string, padding with the supplied character if the supplied string is shorter than desired, or
  truncating the string if it is longer than desired. Unlike {@link #justifyLeft(String, int, char)}, this method does not
  remove leading and trailing whitespace.
  
  @param original the string for which the length is to be set; may not be null
  @param length the desired length; must be positive
  @param padChar the character to use for padding, if the supplied string is not long enough
  @return the string of the desired length
