I prefer to only cover the most common cases as localized joining methods on `Collectors` that take a `Locale`. Other less common cases may rely on the initially proposed `ListFormat`'s instance method, or even `ListFormat.format(Stream.toList())`. Still we need to see use cases, though. ------------- PR Comment: https://git.openjdk.org/jdk/pull/32716#issuecomment-5764598017
