This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
In K&B SCJP 5 this is the given solution to Chapter 8 Self Test 9 (pages 662/669/670):
First I voted "G", too, but then switched to "F". Because, yes, the semicolon is missing, but the compiler will flag this as an error not until line 8 at the "System".
Enough talking, let's verify:
- Is it really an error in K&B SCJP 5 or am I missing something?
- I looked up the "K&B, SCJP 5 - Errata: Updated 7/28/06" page. A correction to page 669 is given: "669....typo......Answer s/b: A,B,D,E, and F are incorrect" That's even more mysterious to me. First, based on the things above it's not a correction. Second, why "C" is taken away?
- More important: At the real SCJP exam, can you be (on one question or the other) just be "to smart" ;-) ... and should you anticipate and click the would-by-correct-answer even if you know it's wrong :-) ?
hi Volker Glave you are right , but i hope this question is not concentrating on which line Compile Error has occured , but it was the reason why the compilation fails , eventhough the compile Error happen in the line No 8
but the reason was not the illegal statment in line no 8 but it was because of the illegal statement in the line 7 ...
hope i am right ... [ August 16, 2006: Message edited by: Arul Prasad ]

Yeah, this reasoning follows the one given in K&B. But it's not right either. Yes, the illegal statement has to be corrected by adding a semicolon. But this adding does not _necessarily_ has to be on line 7. It could quite equally be added on line 8, for example:
So again, the correct answer to the Self Test question "What is the result?" is "F. Compilation fails because of an error on line 8." - and that's it!, since the error _is_ on line 8.
One has to be merciless about this, I think, since accuracy is one of the fundamentals the SCJP exam is all about in the first place.
First off, I think the errata is correct as it refers to a different question
The exam creation team has consistently reasoned that a question can't be based on the exact response of a compiler, since these responses might vary from compiler to compiler. Hence the phrase "won't compile due to an error on line X", will often appear in answers on the real exam. In other words, in a given situation, (such as, apparently, the question in question) one compiler might complain about line X and a different compiler might complain about line X+1.
The argument that the semicolon could go on the next line of the .java text file is technically valid, but the exam creation team would probably dub that answer "obtuse" In other words, standard java code would always be written with the semicolon at the end of line 7. Sometimes the exam creation team is forced to cram a couple of lines of code together (this is due to space limitiations of the world-wide exam delivery tool), but in such a case the question won't concern the location of an error. So, if the question asks you where an error might be, the code will be of a standard format.
