code: public static boolean startsWith(String string, String prefix) {
          return string.regionMatches(true, 0, prefix, 0, prefix.length());
      }
docs: Indicate if the given string starts with the given prefix. This is a more compact
  way of writing string.regionMatches(true, 0, prefix, 0, prefix.length()).
  
  @param string    String to be tested.
  @param prefix    Prefix to compare against string.
  @return          True if string starts with prefix, case-insensitive.
