Detects when some transformations are performed on Stream API result which could be incorporated into the Stream API call chain directly. E.g.:
  List<String> list = stream.collect(Collectors.toList());
  list.sort(null);
  return list.toArray(new String[list.size()]);
Could be converted to
  return stream.sorted().toArray(String[]::new);
