SCJP 1.4 or 1.5?

Which one is better to take? which is better recognised?
I have checked Sun's website and the only thing I know is:
1) Various changes in topic that will be examined
2) 1.5 is newer (obviously)
yet, there are still many people choosing to take 1.4 instead of 1.5... is there something advantageous in 1.4 compared to 1.5?
Some of you frequent & resourceful ones might have seen my posts when I was learning while practicing Java. Now I think I am prepared to take the test. However, what company will need programmers specialised in Java solely? 2ndly, the description of SCJP says that by passing the exam, the contestants are proved to have basic understanding on structure and syntax of Java. I know Java is quite demanding, but is a SCJP qualified programmer worth anything? or is it just a very basic start in which you need to get other qualifications where SCJP cert. is just a prerequisite?
btw, I did not see any age minimum allowed for taking the exam on Sun's page.... I am 16 now... Do you have to be an adult to take the exam?
please help
thx

However, what company will need programmers
specialised in Java solely? Usually those that have Java software. And as a programmer, you're screwed anyway if you only know one language. Plus, the SCJO may show that you know Java, but it doesn't make you a good programmer.
2ndly, the description of
SCJP says that by passing the exam, the contestants
are proved to have basic understanding on structure
and syntax of Java.What I said. :)
I know Java is quite demanding,
but is a SCJP qualified programmer worth anything? orDepends on where you ask. I India, certainly. OTOH, I think none of my co-workers has the SCJP. (Neither have I.)
is it just a very basic start in which you need to
get other qualifications where SCJP cert. is just a
prerequisite?IMO, it's just gold plating.
btw, I did not see any age minimum allowed for taking
the exam on Sun's page.... I am 16 now... Do you have
to be an adult to take the exam?Depends on your country. You might need your parent's permission to make the deal with Sun. The exam itself has no age limit. There were younger SCJP owners than you.

  • Is it necessary to have an scjp certification to be a java programmer

    hi i have been programming in java for quite some time now , i have heard a lot about SCJP .
    Right now i am in college doing my grad. and java is not a part of our curriculum
    i am quite comfortable with java and want to make my career as a java programmer.
    i just want to know one thing from some professionals on the forum that is it very necessary to have an SCJP Certification if i want to apply in some big companies as a java programmer since i wont be having any other certifications that i have done java .
    please tell me if it would be good for me if i do an SCJP course

  • I want to appear for SCJP.Please help me

    I am a beginner in Java and wants to do SCJP .Please can some one tell me how do i start preparing and how long will it take?

    you start by finding out what you're supposed to know to pass the exam.
    That's the easy part, you should be able to find that information on Sun's certification website yourself. If you can't give up immediately.
    Then you start learning that stuff.

  • SCJP prep help -- bitwise bad boys?

    Hi,
    I'm studying for SCJP so obviously one of the details I have to brush up on are the oft-unused bitwise operators: & | ^ ~
    I'm wondering if there are any mental techniques to using these in your head. Instead of literally writing out the number in binary, performing the comparison, and then re-converting back to decimal.
    Similar to how in grade school we learn that you can take a shortcut of multiplying two long numbers:
    34563
    x 24
    and do these steps:
    3 * 4 = 12, carry the 1
    6 * 4 = 24, add the 1 is 25, carry the 2
    5 * 4 = 20, add the 2 is 22, carry the 2
    4 * 4 = 16, add the 2 is 18, carry the 1
    3 * 4 = 12, add the 1, it all equals 138252
    next line
    then pad a zero on the right
    3 * 2 = 6
    6 * 2 = 12, carry the 1
    5 * 2 = 10, add the 1 is 11, carry the 1
    4 * 2 = 8, add the 1 is 9
    3 * 2 = 6, it all equals 691260
    altogether the answer is 691260 + 138252 = 829512
    In other words, while it's not feasible to add 34563 to itself 24 times (23 actually), there is a trick to figuring it out. Is there something like that for bitwise operators?
    Thanks.

    Thanks -- I finally collated some good tips a few days after I posted that here, with some help from local LUGgers. I'll post them here for the archives:
    Would you mind posting a summary of the helpful tips, tricks, and
    shortcuts sent your way? I'm rather interested in understanding this
    stuff a little better myself.Sure. In fact, they say you really know something well when you can
    explain it to someone else, and this gives anyone a chance to correct me
    if I'm wrong in what I think I know. Here's some of the things I
    learned, combined with what I had already learned from my book (please
    do correct me if I'm wrong):
    1. The unary bitwise NOT operator (~) has a shortcut, but one which
    only works when two's complement is in effect. On systems in which
    one's complement is in effect, it doesn't work. The shortcut is that
    any number n has a bitwise NOT of -n - 1. So
    ~5 == -6
    ~-12 == 11
    Because I'm fortunate enough to be working in Java where you're writing
    for only one platform (the JVM, which has a spec), I don't have to worry
    about exceptions to this for the test.
    2. Other than the NOT operator, the bitwise operators are binary
    operators, working on pairs of numbers. The bitwise AND operator
    returns a 1 for each pair of bits that are both 1.
    So in the case of
    11001 & 10011
    the result is 10001 (because only the first and last digits are both 1).
    The bitwise OR (|) operator returns a 1 for situations in which either
    pair of bits has a 1.
    So in the case of
    11001 | 10011
    the result is 11011 (because the only place in both numbers where there
    is no 1 is the third digit).
    The bitwise XOR (^) operator returns a 1 for situations in which either
    pair of bits, but not both, has a 1 (hence the name "exclusive OR", or XOR).
    So in the case of
    11001 ^ 10011
    the result is 01010 (because in the first, third, and fifth digits,
    either both numbers are 0 or 1).
    The short circuit operators AND (&&) and OR (||) work just like their
    regular counterparts except they stop evaluating once they "know" the
    result (AND stops evaluating if the first operand is false, and OR stops
    evaluating if the first operand is true).
    3. So my original question, "does anyone know any mental shortcuts for
    working with bitwise operators", should have been phrased as "does
    anyone know any mental shortcuts for converting decimal numbers to
    binary". The answer, which a couple of people provided, was that it's
    much easier to convert to binary (even if only in your head) when you
    are working from octal or hexadecimal, and that it's not too difficult
    to convert from decimal to octal or hexadecimal.
    Several ways were suggested:
    a) Convert the number to hex, then do the comparison a byte at a time in
    your head using a table:
    & 0x01 0x02 ... 0xff
    0x01 0x01 0x00 0x01
    0x02 0x00 0x02 0x02
    0xff 0x01 0x02 0xff
    b) Convert the number to octal using a simple recursive divide-by-eight
    solution:
    divide the number by eight, store the remainder as the low bit depth
    (rightmost number), then repeat the process with the quotient.
    123 / 8 = 15 remainder 3 -- 3 is rightmost digit (3)
    15 / 8 = 1 remainder 7 -- 7 is next to 3 (73)
    we don't divide 1 by 8 -- 1 is next to 7 (173)
    so 123 in octal is 0173
    From octal it's much easier to see the binary form of the number:
    1 7 3
    001 111 011
    And from binary it's much easier to do a bitwise calculation.
    c) Another way to convert to binary is to simply keep dividing by two
    and assigning 1 if there's a remainder and 0 if there isn't, then read
    in reverse to get the binary number:
    <quote>
    If a number is even, dividing it by 2 will have 0 remainder.
    If it is odd, dividing it by 2 will have a 1 remainder. Dividing
    by 2 is so easy that I, at least, can just write down a column of
    successive halvings, along with 1s and 0s for their oddness.
    459 1
    229 1
    114 0
    57 1
    28 0
    14 0
    7 1
    3 1
    1 1
    Reading from bottom to top, we again get 111001011. In this
    presentation you stop when the quotient is 1, since you've already
    written down the remainder that you'd get by dividing 1 by 2 when
    you write down the oddness. Remainder when dividing by 2 is easier
    than quotient.
    </quote>
    d) A final useful tip mentioned: as long as x is not zero,
    x & -x
    will always evaluate to a power of two, which means only one bit is set
    in the number (the least significant of the bits of x that were 1s).
    4. And everyone agreed that it's foolish to do these kinds of
    computations in your head when there's no good reason not to use a
    computer to do it. My personal preference is to use Python since the
    interactive interpreter works just like a calculator, though any
    scripting language should probably be able to handle the calculations.
    (Here's a quick sample:)
    |$ python
    |Python 2.2.2 (#1, Dec 31 2002, 12:24:34)
    |[GCC 3.2 20020927 (prerelease)] on cygwin
    |Type "help", "copyright", "credits" or "license" for more information.
    |>>> 12 & 14
    |12
    |>>> 12 | 14
    |14
    |>>> 12 ^ 14
    |2
    |>>> ~12
    |-13
    |>>> myResult = 0x5422CA66 & 458
    |>>> myResult

    |>>> hex(myResult)
    |'0x42'

    Hey Thanks
    i would like to know one question's answer.
    as i heard Sun Exam voucher is the same for all the exams (SCJP,SCWCD,SCBCD,SCDJWS,SCJA,SCEA-Part1,SCMAD).
    so how do i will get for scjp 1.6 exam voucher i need to ask in examination center or while scheduling i can schedule for SCJP 1.6.

  • Cannot schedule SCJP 5.0

    Hi All,
    I really need some advice please help me.
    I try to book SCJP 5.0 exam on Prometric, but when I try to submit it the form it says �Invalid Email address� under the part, �Sun Microsystems need further information�
    And does not let me confirmed the booking.
    What I couldn�t understand is why this error is coming up although I have registered and paid Sun Microsystems using the same email address. Also I received confirmation along with the voucher details from Sun to the same email address.
    I wonder whether any of you encountered this problem when registering with prometric for Sun exams?
    This is the second time I have paid for SCJP 5.0 and on the first occasion the rescheduling process didn�t work and my money was lost. I requested Sun Microsystems to looking in to it but I have never received any feed back as of today. Any help and advice is much appreciated on how I could proceed with this matter.
    Sincerely
    Dela

    I got the same error. Instead of typing NONE for the SunID, type [email protected] and it should let you commit the registration. Being an ASP.Net developer sometimes helps :)

  • SCJP Practice Question

    I'm working through the McGraw Hill SCJP study guide for Java 5, and I don't much care for the following question:
    (page 159)
    5. Select the two statements that best indicate a situation whit low coupling. (Choose two.)
    A. The attributes of the class are all private.
    B. The class refers to a small number of other objects.
    C. The object contains only a small number of variables.
    D. The object is referred to using an anonymous variable, not directly.
    E. The reference variable is declared for an interface type, not a class. The interface provides a small number of methods.
    F. It is unlikely that changes made to one class will require any changes in another.
    Answer:
    E and F are correct. Only having access to a small number of methods implies limited coupling. If the access is via a reference of interface type, it may be argued that there is even less opportunity for coupling as the class type itself is not visible. Stating that changes in one part of a program are unlikely to cause consequences in another part is really the essence of low coupling. There is no such thing as an anonymous variable. Referring to only a small number of other objects might imply low coupling, but if each object has many methods, and all are used, then coupling is high. Variables (attributes) in a class should usually be private, but this describes encapsulation, rather than low coupling. Of course, good encapsulation tends to reduce coupling as a consequence.
    I would have thought A and E were the answers here. If the attributes of a class are all private, you're going to have to use accessors and mutators to get to them, which is a prime example of loosely coupled code. I disagree that "F. It is unlikely that changes made to one class will require any changes in another." is a proper answer because although it does cut right to the heart of the matter, it does not describe the mechanism through which this feat has been accomplished and leads me to believe that perhaps the class has been designed with likely future changes in mind such that they will have a low impact but other unforseen changes may cause problems.
    Am I out of line here?
    If so, please enlighten me!
    If not, ... yarrrgh! If there are questions like this on the exam, I expect to have problems with them. Any suggestions? How can I get my reasoning to line up with the test, at least for the day of the exam? ;)
    Thank you in advance for any assistance!

    I think you're making a general mistake you have to come to terms with before you attempt the exam. You're reading stuff into the statements that aren't there. You must learn to consider the statements just as they stand and don't modify them in your mind.
    For example,
    If the attributes of a class are all
    private, you're going to have to use accessors and
    mutators to get to them,That's not what the statement says. It says all attributes are private, nothing else.
    it does cut right to the heart of the
    matter, it does not describe the mechanism through
    which this feat has been accomplishedWho said mechanisms must be provided? The statement cuts right to the heart of the matter as it stands.

  • Question related to SCJP 6 certification

    Hi Everyone,
    Just have question related to SCJP Exam.
    I have started to prepare for SCJP 6 from yesterday (3-4 hours in a day) and I am planning to take SCJP exam in march last week. can u suggest books, which I need to go through..and also I need to write exam at earliest..Do I need to take more than one month for preparation....or less than that is it possible for good knowledge and score?
    Thanks,
    Naveen

    Hello Naveen,
    I am also goining to write SCJP1.6 exam(hopefully this month end).
    I am referring Kathy Sierra, Bert Bates SCJP1.6. It is an awesome book and it include 350+ mock question excluding the ones you get at end of each chapter.
    I dont know whats the level of your Java knowledge. In my opinion someone who has a fair amount of knowledge of the subject should take atleast 2 month of preparation before taking the exam. Syllabus for SCJP6 is more or less easy(except for few concepts) but you know what makes it a difficult exam is the minor details which we tend to ignore while studying the Java subject.
    Also the questions will contain more than 1 correct answer which you cant answer correctly unless you have pracised a lot of mock exams.
    So my advise to you is :take time to brush up the minor details of the subject and do lot of mock tests. That ways you can ensure good marks.Dont hurry, else you may clear the exam but not with good percentile.
    Thats all knowledge I wish to give you.
    Let me know if you want some more.
    Best of Luck for your exam,
    Best regards,

  • What are the advantages of SCJP??

    I know SCJP is a certificate acknoledging your Java programming level.
    But, is there any realistic advantage??
    Secondly, I see there are slightly different versions of SCJP, for eg, 1.2, or 1.4 platform. What makes them different??
    Apreciate any response

    I know SCJP is a certificate acknoledging your Java
    programming level.Kind of. It says nothing about the quality of the code you'll write.
    But, is there any realistic advantage??Depends. It seems that in some parts of the world, the recruiters value it. In other parts of the world, it's just a sheet of paper.
    Secondly, I see there are slightly different versions
    of SCJP, for eg, 1.2, or 1.4 platform. What makes
    them different??<sarcasm>
    Hm. There's a SCJP for Java 1.3, one for 1.4, one for Java 1.5... I wonder where's the difference, too.
    </sarcasm>
    Different Java versions, different features, different tests. As simple as that.

  • Recommendations for SCJP 6 practice exams

    I everyone, I am new to this forum but I have gotten a lot of help from this forum so far. This is my first post. And please excuse me and direct me in the right direction if someone else has already asked and gotten an answer for this questions.
    I am taking the SCJP 6 this AUG 4. I wanted to know what practice exam service shall I use (other than the two exams provided by SUN) if I want to get a taste of the real exam. I know there are many sites that provide practice exam packages, but I am afraid they might not be similar to how the actual SCJP 6 exam might look like. Please tell me your recommendations on what sites best depict the real exam scenarios.

    Thank you for your reply, I will check out your recommendations, it certainly helps. But I would also like a recommendation for a practice exam service that I could subscribe to, meaning a portal that will provide me with many practice questions and I dont have to worry about whether they are similar to the questions in the real exam. I know there are services like Ucertify, pass4sure etc...if anyone has used these services could you please comment! Thank you all in advance
