code: public static String[] delimitedListToStringArray(String str, String delimiter) {
          return delimitedListToStringArray(str, delimiter, null);
      }
docs: Take a String which is a delimited list and convert it to a String array.
  <p>A single delimiter can consists of more than one character: It will still
  be considered as single delimiter string, rather than as bunch of potential
  delimiter characters - in contrast to <code>tokenizeToStringArray</code>.
  @param str the input String
  @param delimiter the delimiter between elements (this is a single delimiter,
  rather than a bunch individual delimiter characters)
  @return an array of the tokens in the list
