In section 6.2.3, the following line is offered:

String shortMenu = menu.stream().collect(joining());


indicating that the toString() method of the Dish class will be used automatically. This is an alternative to:

String shortMenu = menu.stream().map(Dish::getName).collect(joining());


However, the shorter version will not compile, at least not on my machine.
