hg: lambda/lambda/jdk: 8023997: j.l.String.join(java.lang.CharSequence, java.lang.Iterable) sample doesn't compile and is incorrect

[Kasper Nielsen]

Hi,

It would be nice if there was a javadoc reference from StringJoiner to
String.join().


And the example posted in StringJoiner

 * <pre> {@code

 * List<Integer> numbers = Arrays.asList(1, 2, 3, 4);

 * String commaSeparatedNumbers = numbers.stream()

 *     .map(i -> i.toString())

 *     .collect(Collectors.toStringJoiner(", ")).toString();

 * }</pre>
Is actually "short" for String.join(", ", numbers);

Maybe an example, joining entries in a map?

Cheers
  Kasper
