Multiple errors - Choose both?

[Lukas Jenny]

Hi,

I took the mock exam C from the book (The one, that you have to download)

Given that compilation fails due to multiple errors. Which of the following answer would you choose:

"A Compilation fails due to a single error in the code."
"B Compilation fails due to multiple errors in the code."

I've chosen B, but the solution says A & B.

Now I'm wondering what I will have to choose tomorrow, when I've got the real exam.

Thanks and best regards
Lukas

Thanks for your time and answer. Sorry, I thought this is not necessary for my question. Her it is:

SCJP Sun Certified Programmer for JavaTM 6 Study Guide (Exam 310-065)
Quiz C for SCJP Sun Certified Programmer for JavaTM 6 Study Guide (Exam 310-065)

Question
Given:

3. import java.io.*;
4. public class Interact {
5. public static void main(String[] args) {
6. Console c = System.getConsole();
7. char[] u = c.readLine("%s", "username: ");
8. System.out.println("hello " + u);
9. char[] pw;
10. if(c != null && (pw = c.readPassword("%s", "password: ")) != null)
11. // check for valid password
12. }
13. }

Which are true? (Choose all that apply.)
Correct Answer
B: Compilation fails due to a single error in the code.
C: Compilation fails due to multiple errors in the code.
E: By default, the readPassword() method echos the users keystokes.

That looks like an error in the mock exam.

If there are multiple errors, then you should choose the answer "fails due to multiple errors."

thank you very much

I hope that you don't mean that the SCJP Study Guide is "the book that you have to download".

Buy the book in a bookstore. The book is not legally available for free on Internet. If you downloaded it for free, you are using an illegal copy.

sorry for the uncleanness, I meant the additional MasterExam that comes with the book...

Wouldn't E as a correct answer also be an error in the mock exam? readPassword() does not echo by default. I think the correct answers should be: C, D

As always, it's possible that there is an error in the book, but before coming to that conclusion I would ask the the *complete* question and answer be posted here - word for word. Sometimes the wording of mock questions is very precise.

Thanks!

Hi Lukas,

I received a screen shot in my mail for this question. You're right, there is an error with this question!

Thanks for spotting it, I'll update the errata list.

I recently ran into this MasterExam question error. I just downloaded the bonus practice exam within the last month so I'm surprised to see such a blatant error still hasn't been corrected.

Also, did I miss it, or is there still no official errata list?

So far the best I found was the topic here: https://coderanch.com/t/467890/java-programmer-SCJP/certification/Compiling-errata-SCJP

One can only conclude that it simply isn't considered very important.

Hey Can someone explain why multiple errors.......i think there is only one error where readLine() is invoked......Why multiple errors ??
....And what about the E option doesnt readPassword () echoes the user's keystrokes ??.....please can someone explain ??

Really? On a Java community forum focused on certification you think the practice test quality isn't something to take seriously?

The first error is because the method System.getConsole doesn't exist. It should be System.console(); The second error is that Console.readLine returns a String, not a char[].

And what about the E option doesnt readPassword () echoes the user's keystrokes ??.....please can someone explain ??

And if it doesnt do echoes by default which method should we invoke in order to echo the password ??

Just look at the JavaDoc API: http://download.oracle.com/javase/6/docs/api/java/io/Console.html

You'll see that if you use the readPassword method that the user's keystrokes are not echoed. If you wanted to echo the user's keystrokes you could use the readLine method instead (which means you would also get a String, not a char[]).

No, that is not at all what I wrote. I wrote this:
