  }/*from  ww  w  .  ja  v a 2s.  c  o m*/

  public static final String EMPTY = "";
  public static final int INDEX_NOT_FOUND = -1;

  public static String substringAfterLast(String str, String separator) {
    if (isEmpty(str)) {
      return str;
    }
    if (isEmpty(separator)) {
      return EMPTY;
    }
    int pos = str.lastIndexOf(separator);
    if (pos == INDEX_NOT_FOUND || pos == (str.length() - separator.length())) {
      return EMPTY;
    }
    return str.substring(pos + separator.length());
