stateCodesAreSorted Test Fails in the ranges stream challenge.

this is a snippet of my stream() function

If someone could point me in the right direction as it looks like I am missing something here!

public static List<String> getStateCodesFromRecords(List<HousingRecord> records) { // TODO: Open a stream on records // TODO: Map the stream to the state code // TODO: Filter out any records without a state // TODO: There are duplicate state codes in the records, make sure we have a unique representation // TODO: Sort them alphabetically // TODO: Collect them into a new list.

return records.stream()
  .map(HousingRecord::getState)
  .filter(String::isEmpty)
  .distinct()
  .sorted(String::compareTo)
  .collect(Collectors.toList());

}

hey I found a solution for your little errors , hope it works. For me I forgot to add +1 to stateCode.size() for the other method.
