6,784 PointsstateCodesIgnoreBlanks FAILED and not sure why
I've tried the following solution and the test is still failing. Any idea why?
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 Collections.emptyList(); return records.stream() .map(HousingRecord::getState) .filter(Objects::nonNull) .distinct() .sorted() .collect(Collectors.toList());

6,784 PointsNever mind. I found the answer. It looks like they are looking for the following filter: .filter(state -> !state.isEmpty())
