[Sybex] Errata Contribution Introduction, Page xli Possible Typo

[Lake Greene]

In "Answers to Assessment Test" on pages xli-xlii, the explanation states:

14. D, E, F. The code compiles without issue, so options A and B are incorrect. If house.getChickens() returns an array of one element, the code will output Cluck once, so option D is correct. If house.getChickens() returns an array of multiple elements, the code will output Cluck once for each element in the array, so option E is correct. Alternatively, if house.getChickens() returns an array of zero elements, then the code will throw an IndexOutOfBoundsException on the call to house.getChickens().get(0); therefore, option C is not possible and option F is correct. The code will also throw an exception if the array returned by house.getChickens() is null, so option F is possible under multiple circumstances. For more information, see Chapter 2.

However, on pages xxxvi-xxxvii, the question states:

14. Assuming we have a valid, non-null HenHouse object whose value is initialized by the
blank line shown here, which of the following are possible outputs of this application?
(Choose all that apply)
1: class Chicken {}
2: interface HenHouse { public java.util.List<Chicken> getChickens(); }
3: public class ChickenSong {
4: public static void main(String[] args) {
5: HenHouse house = ______________
6: Chicken chicken = house.getChickens().get(0);
7: for(int i=0; i<house.getChickens().size();
8: chicken = house.getChickens().get(i++)) {
9: System.out.println("Cluck");
10: } } }

In the prompt, getChickens() returns a List, not an array as explained in the answer. I believe this is a typo.

Can someone confirm that this is a typo?

You are correct! I've added this to the errata. And given you two cows. Nobody reported this in over 6 years. Good attention to detail.
