Looks like they added these codes for the 2nd edition. link You can try return menu.stream().filter(dish -> dish.getCalories() > 500).collect(groupingBy(Dish::getType)); which will run fine with a java 8 compiler giving the same result. But my $0.02 would be to use the latest jdk if possible.

switch to previous commit to get first edition code.

git reset --hard ae8122f433f90a8bfed7244cdf6f99271f1d1125
