Hi,

I think there is an errata on Chapter 8, on the Review Questions:

On the explanation of Question 2 (tb864585.JaSE17SG.c08.02):



Options:
A. ok
B. too high
C. Compiler error on line 7
D. Compiler error on line 10
E. Compiler error on a different line
F. A runtime exception is thrown.

Explanation:

The interface takes two int parameters. The code on line 7 attempts to use them as if h is a String making option C correct. It is tricky to use types in a lambda when they are implicitly specified. Remember to check the interface for the real type.



Shouldn't it be "The code on line 7 attempts to use them as if h is a StringBuilder" ?

Thanks,
João

Confirmed and added to the errata. This was wrong in our Java 11 book as well. Have a cow for being the first one to notice!
 
No matter. Try again. Fail again. Fail better. This time, do it with this tiny ad:
