[Brian Goetz]

What you should have written was:

  String s = whatever.stream().collect(joining(", "));

Sorry, I should've written this:

          Iterable<?> whatever = ...
          StringJoiner joiner = new StringJoiner(", ");
          whatever.forEach(w -> joiner.add(w.toString()));
          String s = joiner.toString();
