Hi, all,
just discovered an error in the famous 'Java 2 Certification Study Guide' (Roberts, heller, Ernest). They say that application's main method may be

The fact is that it cannot (I run test and got an error from vm launcher). So I wonder : can we believe this book in general?

Are u referring to Q3 at the end of chapter 1.If so,pl.check : the answers r given as B,D only.The option ur referring to is E.
I have RHE too.It doesn't give
public static int main(String [] arg) ,as a valid declaration.The return type for main() has to be void.

According to the above reply, it doesn't look like this is really an error. However, I believe that book is pretty sound, factually, so I think you'd be pretty well off believing what it says.

Check the errata page. This is listed.
"Page 716
3. Which of the following signatures are valid for the main() method entry point of an application? Answer: B and D"

This book can definitely be trusted. It was co-written by one of the authors of the exam.

My copy of the book also says B,D,and E are the correct answers. That's why you need to check the errata pages.
