errata for K&B book?

[f8]

Hi
I want to point out the wording of answer #8 on p.142 of K&B's SCJP book caused me hours of frustration. :roll: :roll:

It says "Nonested classes cannot be protected(or final for that matter..."
I understand that no class can be marked protected, and IN THIS CASE because there is a SUBCLASS, the parent class should not be marked final, BUT.. it comes across that no non-inner class should ever be marked final, which is not true. Is there an errata for this book?

Also, in question 3 of the same self-test, the use of the word "implement" is taken to mean that there is code in the curly braces AND the word abstract is removed for a method, in particluar for choice F. Will the actual exam be more clear, or will I be able to ask someone to clarify that during the test? I would have expected it to state clearly that the keyword was removed. I thought that implement meant write code in the curly braces, which together with the abstract keyword would cause a compilation error, making F a valid answer.

I believe the post is same as https://coderanch.com/t/248260/java-programmer-SCJP/certification/book-where-nd-edition-errata

It is better not to post the same message.

However, we do appreciate that you've registered a new account with a valid name. Thanks. To avoid confusion, I'll close the old post and keep this one open. Usually though we prefer not to duplicate posts, as it confuses people and splits up the responses (so when I respond, I may not see that someone else has already said the same thing in another thread).

Really
Can someone answer the Java questions I posted

[Carol Enderlin]

What java questions? In the post above I see a question about the errata and a question about the exam.

Is there an errata for this book?

Yup, the errata can be found here.

It says "Nonested classes cannot be protected(or final for that matter..." I understand that no class can be marked protected, and IN THIS CASE because there is a SUBCLASS, the parent class should not be marked final, BUT.. it comes across that no non-inner class should ever be marked final, which is not true.

The statement "Nonnested...." on pg 142 has already been corrected in the errata.

will I be able to ask someone to clarify that during the test?

Nope. That's not possible.

I would have expected it to state clearly that the keyword was removed.

How did you interpret the statement "If class A was not abstract..."?

I thought that implement meant write code in the curly braces, which together with the abstract keyword would cause a compilation error, making F a valid answer.

Is this what you're saying?

abstract class A {
    short m1() {
        return 38;
    }
 
    short m2() { return (short) 420; }
}
...

If so, it'll not cause compilation error. Even if "abstract class A" contains all the implemented methods like the one above, it is still an abstract class.

PS: Luckily, you're not the real Mrs. Moose, otherwise I'd be heartbroken. Now that I know Mr. Moose is still single, I'm so happy. Just kidding.

f8, you have been warned multiple times, and constantly changed your display name to one that is a blatant out of our policy. If you do not change to your real first and last name, we will close your account.
