hi

can anyone give some information about scjp 1.6, which is the book for it?
are there sufficient materials for it or not?

should we go for 1.5 or 1.6?

thanks

There is no SCJP for Java 1.6, and Sun has not made a public announcement of whether or not there will be one.

As far as I can tell from the SCJP 1.6 exam objectives, the only differences are:

  • Section 3:


  • 1.5: Given a scenario involving navigating file systems, reading from files, or writing to files, develop the correct solution using the following classes (sometimes in combination), from java.io: BufferedReader,BufferedWriter, File, FileReader, FileWriter and PrintWriter.

    1.6: Given a scenario involving navigating file systems, reading from files, writing to files, or interacting with the user, develop the correct solution using the following classes (sometimes in combination), from java.io: BufferedReader, BufferedWriter, File, FileReader, FileWriter, PrintWriter, and Console.

  • Section 5:


  • 1.5: Given a scenario, develop code that declares and/or invokes overridden or overloaded methods and code that declares and/or invokes superclass or overloaded constructors.

    1.6: Given a scenario, develop code that declares and/or invokes overloaded methods and code that declares and/or invokes superclass, or overloaded constructors.

  • Section 6:


  • 1.5: Write code that uses the generic versions of the Collections API, in particular, the Set, List, and Map interfaces and implementation classes. Recognize the limitations of the non-generic Collections API and how to refactor code to use the generic versions.

    1.6: Write code that uses the generic versions of the Collections API, in particular, the Set, List, and Map interfaces and implementation classes. Recognize the limitations of the non-generic Collections API and how to refactor code to use the generic versions. Write code that uses the NavigableSet and NavigableMap interfaces.

  • Section 7:


  • 1.5: Given a code example, recognize the point at which an object becomes eligible for garbage collection, and determine what is and is not guaranteed by the garbage collection system. Recognize the behaviors of System.gc and finalization.

    1.6: Given a code example, recognize the point at which an object becomes eligible for garbage collection, determine what is and is not guaranteed by the garbage collection system, and recognize the behaviors of the Object.finalize() method.

    All of these seem like relatively minor changes, with only three new classes/interfaces (Console, NavigableSet, NavigableMap) added to the set of APIs that will be tested. None of the key Java 6 features (e.g. Scripting API) seem to be covered. Also, the pass score has been raised from 59% to 65%, while the total allotted time has been raised from 175 min to 210 min.

    Given that the exam isn't actually available yet, I'd suggest that you just proceed with SCJP 1.5 preparation for now. If SCJP 1.6 becomes available before you schedule your exam, you can then just learn the few additional topics needed for SCJP 1.6, if you wish. There doesn't really seem to be anything in SCJP 1.5 that was removed in 1.6, so none of your effort in learning the 1.5 material will be wasted.

    And if you're already SCJP 1.5 certified, my preliminary assessment is that there's not enough of a difference to make it worth the effort to take the upgrade exam. Wait for Java 7. =)

    Kelvin, thanks so much for taking the time to compare the two objectives sets. You saved me a lot of time

    It indeed seems that the differences are minimal, so I'm curious how the the upgrade exam is going to work? You can't really make an exam out of three classes, can you?

    None has been announced so far. In fact, the SCJP 1.6 itself hasn't really been announced yet; all we know is that the Sun web site now lists the exam objectives for the SCJP 1.6 and the SCJP 1.6 Upgrade. We'll just have to stay tuned.

    speculation: perhaps this is a prelude to the scjp1.4 being retired.

    Christian, are you absolutely 100% certain? In my 10 year tracking of the SCJP Sun has never released a new version of the exam without previously announcing that there would be a beta test period. I find it hard to understand how Sun Germany would be selling vouchers to a an exam that can actually be taken now yet Sun US/World wide was not. It seems much more likely that Sun Germany are not in full posession of the facts.

    It looks to me as if that is a training course for the exam, not the exam itself.

    Actually, I think Christian's right. Sun's US site now also indicates that SCJP 1.6 vouchers are available for purchase, and Prometric's site seems to allow you to register for the exam. It looks like Sun really did launch the exam without a (public) beta.

    I think you guys might recall that if you took the 5 exam over the last couple of months, there were some "extra", unscored questions on your exam. That was an informal "beta" for the SCJP 6 exam, since the SCJP 6 is such a small change from the SCJP 5.

    Ah, so that's why people were reporting that they saw 82 questions instead of the usual 72. Sneaky, sneaky.

    Hi everyone, later i saw all your post, i decide to take the SCJP 6, i was very preparate for the SCJP 5, but with the new version some stuff was add, like Console, NavigableMap, NavigableSet... and i dont know what anything else.

    I am request for some one to know where i can download o see this material to study, the rest of certification

    SCJP 5 -> 100% preparate
    SCJP 6 PLUS -> 0% preparate

    Very Thanks.

    "and i dont know what anything else."

    Kelvin has kindly highlighted the differences

    "Console, NavigableMap, NavigableSet... "

    New features of Java 6 that I did not know even existed until yesterday even though I program Java for a living and read everything I can on the subject. It seems to me that these are not big deal important features of Java (unlike annotations which are on neither versions of the exam).

    The choice is yours but why make life harder for yourself. It's not that uncommon for candidates to fail the SCJP, the exam cost is not trivial and employers generally know almost nothing about the differences between the exams.

    Hi Bert !

    Do you mean people were asked Java 6.0 stuff during Java 5.0 test ?

    People may not be aware of some super-new Java 6.0 features, so results of such beta session may be not reliable.

    I�m also mixed up by the availability of 1.6 exam as i�m going to
    take on of both during this month (hopefully).

    Despite also having never heard about this 3 new topics in 1.6 exam,
    there seems to be one real remarkable benefit:
    the testee has 210 instead of 175 minutes time but no additional question.
    As i�m afraid that my speed of thinking could realy be limiting factor (for nice percentage at least) this seems to be very attractive.

    But of cause i�m full of doubts : what is the cost for this additional time?
    Can i expect the same question pool as in 1.5 exam (so the questions we all are or were prepairing for) and just a handfull of them replaced by new 1.6 things or will there be a complete new (and maybe more complicated) question pool which would explain the additional exam time?

    How was it as 1.5 came up with respect to 1.4 ?

    Don't forget that the pass percentage has gone up from 59% to 65%, though. That basically means you need to get four more questions correct than for SCJP 1.5.

    I found some additional information here, maybe someone`s interested in:


    NEW SUN CERTIFIED PROGRAMMER FOR JAVA PLATFORM 6 EXAM
    What are the differences between Sun Certified Programmer for Java Platform 5 (CX-310-055) and 6 (CX-310-065) exams?

    Questions concerning System.gc() have been removed.
    Coverage of the java.io.Console class has been added.
    Coverage of navigable collections has been added.
    Several of the previous objectives have been strengthened (so you can expect more questions and more detailed questions on them). These strengthened objectives include: exception handling, collection classes and collection interfaces, assertions, threads, and flow control.

    To take the SCJP 1.6 upgrade exam, I am required to have a SCJP 1.5? or can I take the exam having just the 1.4 version? The page on the upgrade exam tells:

    # Prerequisites: None
    # Other exams/assignments required for this certification: None

    Which is obviously wrong, as this is an upgrade exam.

    Hi,

    i got many emails with questions regarding the java 6 exam. PLEASE STOP ASKING VIA EMAIL OR PRIVATE MESSAGE! Post a reply in the board instead!

    Here my answers to the questions:

    i can not compare the java 5 to the java 6 exam. (i only made the java 6; and i'm not allowed to write details about the real exam questions - you know!)

    My study time was about 150+ hours in the last half year. 95% of the time i studied with java 5 material and mock-questions.

    I can recommend training with this book (and the included mock-exams):

    SCJP Sun Certified Programmer for Java 5 Study Guide ISBN-10: 0072253606


    Sun Tutorials are very helpful, too:

    Sun Tutorial's (e.g.: generics, collections,...)


    I can also recommend to read the java 6 exam objectives in detail and
    to study all the topics. See also this entry (very good!):
    "November 30, 2007: Message edited by: Kelvin Lim" in

    scjp 1.6



    Here is a small FAQ from sun regarding the java 6 exam:

    Christian, it's stated that a bunch of topics was strengthened for the SCJP 6 exam, so could you compare the toughness of the mock questions you were using to prepare to the exam with the real questions? Also, were there any seemingly new topics (save the Navigables and Console) that you were unprepared for?

    Hi,
    the mock questions/selftest-software in the book was good enough! I think "strengthened" means: "more questions regarding the specified topics". I think the mock questions in the book were a litte bit more difficult.
    I prepared a few hours for the new topics. i used the objectives and the information from "Kelvin Lim".

    Hello. I purchased a voucher for the 5.0 exam last year. Now I see that the 6.0 exam is available. I have not yet given the exam.
    Can I use the voucher to register for the 6.0 Exam instead ?

    hi,

    Thanks Kelvin for the info on the differences between scjp 5 and 6 exams. Just a little correction on overloading and overriding in section 5. There appears to be no difference, so all for the better!

    Section 5:

    1.5: Given a scenario, develop code that declares and/or invokes overridden or overloaded methods and code that declares and/or invokes superclass or overloaded constructors.

    1.6: Given a scenario, develop code that declares and/or invokes overloaded methods and code that declares and/or invokes superclass, or overloaded constructors.
