Question error OCA / OCP Java SE 8 Programmer Practice Tests (Sybex ocapt.79)

[Jens van Groeningen]

This question is about how many lines of the class do not compile and the line stating: 'protected in sing;' is not counted towards the total while this line clearly does not compile.

[Jens van Groeningen]

Oh and it also includes a line 'date = date.minusMonths' which also does not compile

[Jens van Groeningen]

I have attached a screenshot of the question to improve clarity on the error.
Would like to see this error added to the Errata page.
Kind regards

That looks like a rendering error or some sort of weird manual edit! This is what is in the book for that question.

79. How many lines of the following class do not compile?

1: package arctic;
2: abstract class Bear {
3: protected int sing;
4: protected abstract int grunt();
5: int sing() {
6: return sing;
7: }
8: }
9: public class PolarBear extends Bear {
10: int grunt() {
11: sing() += 10;
12: return super.grunt()+1;
13: return 10;
14: }
15: }

Added to errata crediting you and linking to this thread. It's annoying to me because this was right in the printed book!
