Scjp preparation

Hi,
I am recently came to know that certification will plays a vital role in our career. Now I'm intereted in preparing for scjp. I know jdk 1.4 but not much 1.5. What is the suitable and helpful in future to take certification?
Is it compulsory to take training from sun like Java Programming Language (SL-275) and some other? I can't pay the additional amounts.
I'm practicing with javaranch roundup games and mock test papers and have books Complete Java 2 Certification Study Guide by Simon Robert, phillip heller n michale... and Sun Certified Programmer & Developer for Java 2 Study Guide by Kathy Sierra.
Is it right that exam simulators very useful. Can u give some free sites for it?
Please help me in getting information or any other suggesions for the preparation...
Thanks.... __Anand

What are the perfect SCJP preparations ?

well, I have some good experience with java SE and planning to take one of those SCJPs.
I'm really new to this, so please, would you advise me of what I should do??
How can I prepare for the exam ? and what books do you recommend to read...
Actually, I'm ready to study hard but I lack the good material ...so I would appreciate the help :)
another issue, we all know that scjp 6 has been released lately, so what do you recommend?
get the scjp 5 or 6?
of course this will affect the material I should read, too.
Thanks in advance :)

How can I prepare for the exam ? and what books do you recommend to read...If you already have several years of experience, study the language specification and make a lot of mock exams.
Revising the javadoc for especially the java.lang and java.util packages is a good idea as well.
And work your way through one of the seminal works about the exam, like Kathy Sierra and Bert Bates' masterwork.
While you may think you know a lot, that material will make you wonder how you got by all that time with such gaps in your knowledge about the language.
That is normal. Most people in their working life use only a relatively small portion of the entire platform.
Actually, I'm ready to study hard but I lack the good material ...so I would appreciate the help :)
Always good to see someone who wants to understand the material rather than cram for the exam.
another issue, we all know that scjp 6 has been released lately, so what do you recommend?
get the scjp 5 or 6?IMO the entire Java6 release should never have seen the light of day, but apart from that IMO one should go for either the exam that best fits with what one uses in ones work or with the very latest.
of course this will affect the material I should read, too.
Not that much I think. The differences in the core language are rather small, it's mainly the idiocy that was added like embedded database engines and webservers that make 6.0 different (and a disaster).
Might be difficult to get 6.0 exam materials btw.

Give good suggestion for prepare for SCJP and meterials?

what are good sites for Scjp preparation ?

Hi,
Be a good programmer rather than being a certified person.
I don't know y people give much importance to SCJP.
In my opinion any technical sound person can clear this exam with little bit of concentration on basics.
For an entry level professional it is not at all advisable to go for SCJP. Instead work on analytical skills , technical skills development .
After getting experience it is better to go for certification, if he really wants to fill a resume with one more coloumn

Regarding scjp

how should i start my scjp preparation?

Go to the SCJP forum at www.javaranch.com. That site specializes in certification and everyone is always helpful, their motto is "be nice".
Also you might want to get one of the books that they recommend, yes, Kathy Sierra runs that site, but her books are good. and you can use the free mocks on Dan Chisholm's site, www.danchisholm.net

SCJP 6 Dump / Practise Exams / Exam Simulator

Hi Gurus,
Am new to SCJP preparation. It would be great if somebody can give guidance regarding finding good source for exam dump / questions / practise tests etc., I am an OCP before, graduated 2004. I know the practise tests and questions makes a big deal while preparing cert exams.
Thank you.

I recommend this book http://www.amazon.com/SCJP-Certified-Programmer-Java-310-065/dp/0071591060/ref=sr_1_1?ie=UTF8&qid=1292010257&sr=8-1.
It contains all that you need to pass the exam including practise test. Also, if you want to try on simulators before taking the real one, I will recommend this site http://www.whizlabs.com/.
Note that I have used the mentioned materails to pass the exam on OCJP6 and I think it will help you a lot. :)

A generic compilation problem......

I have the following method code......
public static <E extends Number> List<? super E> process(List<E> nums){
     return null;
    }I am trying to invoke this in main() method using the following:
        List<Number> input = null;
        List<Number> output = null;
        output = process(input);   //line 3But in //line 3, i get the compilation error that
found   : java.util.List<capture#183 of ? super java.lang.Number>
required: java.util.List<java.lang.Number>
        output = process(input);
1 errorI am getting the same error even when i use
       List<Integer> input = null;
        List<Number> output = null;
        output = process(input);I believe the above invocations are correct. What is the problem then??

All right, i get it now.
It's funny that i've taken this question from an SCJP preparation book, and the answer suggested by you is not there. Even their analysis is incorrect.
So, the reason you had to change it from List<Number> to List<? super Number> is that the method return type is defined that way in method definition. More specifically, if '?' wildcard is used in method definition for the passed type, we have to pass the argument exactly the same way (with ? wildcard) in method call.
Is my understanding correct?

Objects & garbage collection

Hi. There is a question in scjp preparation and I wish to know more about the explained answer:
Given:
3. class Dozens {
4. int[] dz = {1,2,3,4,5,6,7,8,9,10,11,12};
5. }
6. public class Eggs {
7. public static void main(String[] args) {
8. Dozens [] da = new Dozens[3];
9. da[0] = new Dozens();
10. Dozens d = new Dozens();
11. da[1] = d;
12. d = null;
13. da[1] = null;
14. // do stuff
15. }
16. }
Which two are true about the objects created within main(), and eligible for garbage collection
when line 14 is reached?
A. Three objects were created
B. Four objects were created
C. Five objects were created
D. Zero objects are eligible for GC
E. One object is eligible for GC
F. Two objects are eligible for GC
G. Three objects are eligible for GC
Answer:
® ✓ C and F are correct. da refers to an object of type "Dozens array," and each Dozens object
that is created comes with its own "int array" object. When line 14 is reached, only the
second Dozens object (and its "int array" object) are not reachable.
Can anyone tell me why its mentioned that there are 5 objects are reported created here.
Also doesn't defining the array of objects create the objects? E.g., in the line number 8, I see three element array is created, doenst this mean 3 objects are instantiated?
Thanks

What is your reasoning for thinking that creating a PLACE to hold three instances has ANYTHING to do with creating those instances?
If you move three bar stools to the kitchen counter in your home does that automatically create a person sitting at each bar stool?
If you create an egg carton that can hold a dozen eggs does that automatically create 12 eggs? If it did why do we need chickens?

HOW TO PREPARE SCJP???

hello to all
I[b] am interested to appear the SCJP exam.
I also in dellima whether I will go for SCJP 1.4 or 1.5. Some of friends tlold that SCJP 1.4 will become obsolute from next year. So, What will be my best choice?
Lastly , can u give me the tips to prepare the exam.

How is the SCJP 1.5 exam different from the SCJP 1.4?
* Exam objectives: Several important new language features have been added, including enums, generics, static imports, and autoboxing/unboxing. API features added to the exam include java.lang.StringBuilder, java.util.Locale, java.util.Formater, java.util.Scanner. java.util.regex.Pattern, and java.util.regex.Matcher. Java IO features have been added, including File, BufferedReader, BufferedWriter, FileReader, FileWriter and PrintWriter. Concepts such as loose coupling and high cohesion have been added, as well as greater emphasis on encapsulation as it relates to JavaBean conventions. Bit manipulation (e.g., shifting) has been dropped.
* Number of questions: 72 (increased from 61)
* Time: 175 minutes (increased from 120 minutes)
* Passing score: 59% (increased from 52%)
* Level of difficulty: The concensus is that it is more difficult.
* Format of questions: As before, you will always be told how many options to choose. No credit is given for partial answers.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal - in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

Preparing for SCJP?

Hi
My name is Jon T and I am a programmer with a local company. I support and develop client�s applications. I use the following in daily process
Unix (HP-UX)
Oracle (Toad)
VB
ASP
etc ..
I have a basic foundation in Java and I am learning and preparing for Java Certificates.
Has anybody passed the test successfully who started from the beginning level?
Say, if I started today, is it possible to pass the test by May/June?

I agree if you are programmer and study an hour or 2(include reading and doing programming practice).
You need to read the book for SCJP. It is better if you can use the quiz and got a score close
to 90%.People recommend the test from whizlab and you have to pay fee.
The questions in the quiz is close to the exam in SCJP and it may help you familiar with the concept.
The book written by Kathy Sierra is good.
There are some free quizs on the internet. I myself have not bought the quiz from whizlab. I succeeded in SCJP 1.4 after one retry.
