comprehensive exam(kathy/Bert book)

[Saith Govind]

import java.io.*;
public class Bing{
Bing(String s){}
Bing(){ }
}
import java.io.*;
public class Bang extends Bing{
Bang(){ }
Bang(String bangS){super(bangS);}
//Insert code here
}
what code if inserted at the comment would not result in any errors
Answers given are
1) Bing b = new Bang(){};
2) Bing b = new Bing(){"Foo";}

But if (2) is placed at the comment, the code does not compile. How is (2) correct??

Saith,
It appears that you are correct. I'm sure that Bert will be here soon to offer a response.

[Valentin Crettaz]

We have discussed that question last week, wait... here it is: http://www.coderanch.com/t/241079/java-programmer-SCJP/certification/anon-inner-class-Sierra-Bates
It seems that the "Foo" thing is a typo since it does not appear in the manuscript I got for the tech review.

[Sarma Lolla]

I agree that it wouldn't compile. But when taking this question I selected that as one of the correct options. Because we need to select two.
I found that there is wrong answer for one of the bitwise operation questions in Master exam 1 and in Master exam 2 there are at least two questions that have wrong anser.
I will post these questions in the coming days on this forum.

Thanks in advance,

Sarma and Param,
We want to thank all the JavaRanchers for using our book!
We try to answer as many posts as we can, but we are not always able to answer them all!
For instance, we will be gone for the next several days.
We have two requests in general:
1) Please check the errata page at wickedlysmart.com
2) If you find an error, please send us an email at wickedlysmart.com (either bert.bates or kathy.sierra).
This way we will be sure not to miss any of the errors that you find!
Back soon!
-Bert
p.s. - Valentin is correct, the question listed at the beginnning of this thread does have a typo

2) Bing b = new Bing(){"Foo";}
Do you suppose what they meant to say is
Bing b = new Bing("Foo"){};
