hi guys,
Iam new to this whole java certification thread.I have thought of taking the SCJP 1.5 somewhere around in July.Could you guys please suggest to me as to which book to start with .I have a basic working knowledge of Java and would like to enhance it further by taking the

exam.my email id is as follows- [e-mail]

[Ben Zaidi]

Hi Parinita,
Actually, i am also planning to give my exam somewhere in End of June
or mid of June, so this the place where you can find all information
definitly.

Well, for SCJP 5.0 examination, the best book is by Kathy Sierra and
Bert Bates, as it is an excellent reference and all people use it for
the preparation. Apart from this, here we are trying that we should
emphasize somewhat not only on passing the examination rather having
good concepts regarding OOP and above all having a decent practise over
solving some Assignments as well. I tried to sketch a plan a bit, and
i am myself starting from Monday the Preparation. Secondly, another good
reference i can suggest is, you can go for Thinking in Java by Bruce Eckel
third edition, its freely available to be downloaded over the net.

Well, i hope ths helps.
Warmly,
Ben

Hello,

I'm willing to join the study group also. I have not set the date for exam, i'll take it when i'm ready. Just ordered K&B. I'm have been java professional for several years, but i want to increase my knowledge.

Don't forget the purpouse of this exam:
To learn Java Programming language properly! This exam is not for designing OO software and doesn't have nothing to do with it. (ok, it helps since you know language fundamentals). Many people seem to forget this fact. The study process gives you tools to learn more.

[amna khan]

Hi!!
I want to join this group.

[parinita rao]

Thanks a ton Benz....
i went out and bought the book just now.and will start preparing from today.It is a really good idea of you guys helping out people wanting to enhance their knowledge of java.

Really looking forward to more value addition thru this group,

Hi folks,

Appreciate the initiative.

Well, I am not pretty sure if forming a study group would be feasible with a forum kind of design(as in Javaranch).

You could open up a Yahoo groups or something for discussion, because I feel posting or growing up the same thread or different threads for questions may sound impractical.

You could then post your study plans or questions or your learning via the group emails, and continue using javaranch as forum, for its purpose.

Please let me know how that would work out

It would be great if the forum administrators also pour in thier thoughts on this. But trust me, javaranch is cool place to learn stuff.

I am not aware if there is already a yahoo group or a google group existing for the javaranchers. If any one knows such groups thing...please let know.

Thanks

[Ben Zaidi]

Hey there.

Thats a nice suggestion to put up, we can really, develop a
Yahoo-Group for Java-Ranchers, where people can post and exchange
emails and it will be a Generic idea for Preparing for SCJP and
also for other kind of difficulties, i will like to a practical step
for creating such a club and give the URL back to you guys. I hope
the healthy collobration for joining will take place. But this is the
thread we initiated so i don't think so we should let this thread go
down, keep it alive.

Thanks,
Ben

[Ben Zaidi]

Hey pals!!
There is a good news, that i have to start a Yahoo Group
for Java Ranchers, specially for people belonging to this
thread... So please lets rock up, i am away but i will be

Hi Ben,

Thanks for creating the groups

I have taken the privilege to be the second member in the groups, kindly approve my membership.

You could also make some one as the moderator of the groups and delegate some responsibilities.

Thank you

[Arad Chear]

[Ben Zaidi]

Hi All..
Please help me publicize this idea, as i can't post the message
separately in every thread about the group creation. This idea
is for you all, and this Club is yours. We can really enhance the
group, by making our group rocking. For this reason, i have created
a new Threa Post too, but it is also a request, if you find any
people who are interested to Join, do tell them also.

Thanks All,
Ben

Hello "Freakenstien"-

Welcome to JavaRanch.

On your way in you may have missed that we have a JavaRanch Naming Policy for displayed (screen) names. Your displayed name must consist of a first name (or an initial), a space, and a family name (in that order) and not be obviously fictitious. Since yours "Freakenstien", does not conform with it, please take a moment to change it, which you can do right here.

Posters with nonconforming displayed names will be locked out of JavaRanch after a few posts using those names.

Thanks

jokes apart, first question, i live in karachi and i've been asking from all the people i know that from where i can get my SCJP cert done...... there was this "tech house" but they stop sun certification long back in 2001.....

i am totally confused what to do and how to do......???
sooo please guide me if anyone lives in karachi as well........

[Ben Zaidi]

Hello Qazi,
Well, first of all Barry is correct, you should please change
the first and last name into a meaningful format, which will
saved your posts from being locked and stuff.

Well, as appearing for SCJP 5.0, first of all the best start
is to have some fundamental knowledge about Java ofcourse and
then you can start with Kathy Sierra and Bert Bates book for
SCJP 5.0 Java Certification. Well regarding the examination side
you need to buy an exam Vouture from Sun's Site and buy the Vouture
which is legal in your Country. There are lot's of center's in
Pakistan and specially Karachi must be having decent Institures
for appearing for SCJP Examination, you just need to check out
more accurately. For more detailed Syllabus of SCJP 5.0, you can
either consult the Sun's Site or you can review my ealier posts
for this Purpose. Well we also have started friendly Yahoo Group
for this purpose as the posts here were getting long. If you want
to share tips, coding techs and stuff, you can join us there. Hope
this helps.

Warmly,
Ben

don't you understand?

alright, my sincere apologies, its actually i never get any objection anywhere else....... but oh well there goes my default display name for forums.....

For Pakistan you should (according to Sun's training info) contact:
United Arab Emirates

yes, i know thats one place, but i have heard people doing SCJP locally, so i was more like looking for a local guy who can tell where and how.......


anyways
@Benz:
well i thought you were from around here.... in khi.......
i know the whole process of buying a vouture and already have the K&B book...... was only making sure that if i can give the test here.....

btw about the study group, tell me where we actually gonna be studying, on this forum or that yahoo group ???
enroll me in, you can get my email from my profile.....

[Ben Zaidi]

Hello,Qazi,
I hope you are doing fine.

Well we are inspired from Javaranch idea and all the information
sharing is gonna be here also, the Study Group was my idea so that
Two minds are better then one and people can share more information.
Well, we all are participating on that Group as well, as Bert has
joined us there, which is a great honor for us. So we will try to
follow the same pattern this great site is following.. well you can
join us there, below the link of my group with my Signature, you can
join us there.

Thanks,
Ben

[Prashantkumar singh]

Thanks,
Ben

[P Bala]

Hi everyone

Sorry that i was not in touch with the group for the past week as my daughter was sick. I am actively starting. I saw benz suggesting to start OOPS concept and another person saying we are going thru K and B book for the Chapter 1. Am little confused as to which book we are following and what is the study strategy. Will greatly appreciate if someone can help me catch up.

Thanks in advance.

[Ben Zaidi]

Hello,
To your latest query, you are most welcome to start the things
again. As we have just devised the strategy and now the participation
for the preparation of SCJP is already started.

Well, thats a study technique i was suggesting, by keepin K&B as
our top priority, but if you go the Table of Contents even the first
chapter is surely about classes and stuff. Priya, we have formed a
Study Group at Yahoo as well, as the message posts were getting too
much here, and for the honor to announce Bert has also joined us there
to help us. My signature includes the URL to the group, you are most
Welcome to Join and lets start the journey together hand in hand.

Well, i am putting up a drafting strategy in the evening today from
my side, because, i have just recieved my copy of K&B book and skimming
it a bit, its an excellent reference to pass the examination with
Flying colors and enhancing the Java Knowledge, now even Bert is there
and i am sure, we will find better ways for our journey to complete.
Well, the strategy will be uploaded in the Group till evening, as
an example, all others are fully Welcome!! to put up their suggestions
but its really high time to get down and start working as a team towards
this goal.

I hope your daughter is in better health now. God Bless her. Looking
foward to hear from you.

Warmly,
Ben

Question
---------
Today i came across a question which was like this

byte b1 = 37;
byte b2 = 7 ;
byte b3 = b1 + b2

now when we add this, it generates a compiler error, why iit does it
because JVM coverts byte, short int and stuff, implicity into Integer.
i need to cast it to byte in order to this statement work, because the
JVM Implementation is like this.

I was curious to know things beyond scenes, when people were designing
the JVM implemenation, why byte casts into an integer, what was the
design thology in their mind, can someone clarify me this point...
I hope Bert you can answer this question more clearly.

Thanks,
Ben

[Barry Gaunt]

If you have questions like this, I suggest that you 1. check previous topics in the forum using the search facility, 2. If you cannot find anything that helps open a new topic specifically for your question - do not post in a topic which perhaps 95% of the people are not going to look into.

In this case, take a close look at the last (to date) post in this topic.. I did a simple search to find it.

[Soma Kora]

Hi,

Im studying K&B book, I didn't undertstand code example given in chapater3:

class Boxing2{
static Integer x;
public static void main(String[] arg){
doStuff(x);
}
static void doStuff(int z){
int z2=5;
System.out.println(z2+z);
}
}
Mentioned in book that, it compiles fine and throws Run time exception and reason being mentioned as " becuase x doesn't refer to an Integer object there is no value to unbox."

doubt: In the above code: doStuff(x), here x is an Integer object since it is a static class variable it has got default value 0. Why is this Runtime exception as mentioned in the book?

Any pointers greatly appreciated.

Thanks
Som.

[Meena R. Krishnan]

I'm getting a compiler error at the doStuff() function call line.
"The method(int) is not applicable for the arguments (Integer).

[Neo Phesus]

Hi Som,

Yes, K&B is right. The code will throw a Null pointer expection. This is basically because, the Integer x is just declared, it does not contain any value or any initialization.

The code will work if the line

    
    static Integer x;
   

is replaced with,

    static Integer x=0; //Or some initial value.
   

Hi Krishna,

I am not very sure why you would get such an error, I would be in a position to explain better if you could let me know if you are using an IDE?? The error should appear only when you are using older version of Java compiler, that is 1.4 or earlier.

Cheers,

[sarvananda sarvananda]

Its so easy, when you wrap your code in [code /].
No wonder it doesnt run. how can you catch an Integer object with a dataype (int). please correct me if am wrong.

[Neo Phesus]

Hi sarvananda,

I am not very sure what you are asking for...

With 1.5's autoboxing and unboxing it should work

Neo
