Example:

  List<String> list = stream.collect(Collectors.toList());
  list.sort(null);
  return list.toArray(new String[list.size()]);

After the conversion:

  return stream.sorted().toArray(String[]::new);

Note that sometimes the converted stream chain may replace explicit ArrayList with Collectors.toList() or explicit HashSet with Collectors.toSet(). The current library implementation uses these collections internally. However, this approach is not very reliable and might change in the future altering the semantics of your code.

If you are concerned about it, use the Do not suggest 'toList()' or 'toSet()' collectors option to suggest Collectors.toCollection() instead of toList and toSet collectors.
