The String {@code "[George:Sally:Fred]"} may be constructed as follows: + * + *
{@code
+ * StringJoiner sj = new StringJoiner(":", "[", "]");

+ * String desiredString = sj.toString();
+ * }
+ * + * A {@code StringJoiner} may be employed to create formatted output from a + * {@link java.util.stream.Stream} using + * {@link java.util.stream.Collectors#joining(CharSequence)}. For example: + * + *
{@code
+ * List numbers = Arrays.asList(1, 2, 3, 4);
+ * String commaSeparatedNumbers = numbers.stream()
+ * .map(i -> i.toString())
+ * .collect(Collectors.joining(", "));
