Hi all,
How many questions does scwcd exam contain and what is the passing mark? Also,can you tell me which publication of "Head First Servlets and Jsp" you are following- Is it Shroff publication or oreilly publication.

Do we need hands on experience to write this exam or is it sufficient if we practice the examples which are present in hfsj.

i have cleared scjp with 88%. Can u tell me certification i should take next. I would like to go for scwcd without passing scjd. Or do i need to know some topics in scjd that are necessary for clearing scwcd or are they mutually exclusive?

Hi Ashok,
I got exactly 38 in the 2 mock exams that come along with the book khalid mughal.But if u go for the full version, they are pretty easy and u will get 48 and above. So, if u are going with the cd that comes along with khalid mughal book then u are good to go, but just revise what all u have learnt till now.I am saying this not to just console u but as it is the truth. I can guarantee that u will get 70+(damn sure) and u can get aboe 80 if u revise well and 90 if u revise and concentrate on the tricy parts in the exam...All the best for u ..do it

And syed, u are right ,i just missed out [], i posted it thinking that i typed [] there.

Hi all,
I just cleared scjp with 88%. Can anyone tell me whether i can directly jump to scjwd without studying for scjp assuming that i do not anything other than what i have studied for scjp?

I would be greatful if u can also suggest the book to follow and the links to get a feel of the exam.

Thanks and Regards,

Hi guys,
I just passed scjp with 88%. Thanks to this forum for giving me support in achieving the same. I could have scored a 100 but i had real problem in the exam in tracing whether an error would produce a run time error or compile error as i studied khalid mughal and k&b without much practice on the system.I could trace the error but i couldnt tell whether the error would produce a run time or compile error.I think i lost 5 marks for this reason. For example,
public static void main(String[] args)
{
Float f= new Float[10] ;
System.out.println(f[0]);
}
Can anyone help me how to recognize a runtime error...is there any thumb rule? I just know that if there is a problem with the syntax,it would produce a compile time error and if there is a problem in checking for the real object it would produce a run time error.

This is how i went about my preparation.
I took 2 months. i just went through khalid mughal first which took about one month(we dont need to go so deep in collections). Then i went through k&b which was real easy and i could complete reading it in 10 days-This book covers what is necessary for the exam.Whichever topics i felt i was not doing well, i did the danchisholm single topic questions...and the last week i went through the k&b once again and my notes.On the last day, i just read the two minute driller and my notes. I scored a 51 in the kathy sierra model exam.

My sincere advice is "please prepare notes when u learn any new point", if u have not done till now, atleast start now...i just starting preparing notes in the last 10 days and found it very useful
ALL THE BEST FOR U EXAM.

Is there any easy method to decode such hex values into decimal values?0x7FFFFFFF


If there is no easy procedure , what is the normal procedure?

class Mine {
static void m1(String s) {
s = s.trim(); s = s.concat("D");
}
public static void main(String[] s) {
String s1 = "A", s2 = " B ", s3 = "C";
m1(s2);
System.out.print(s1 + s2 + s3);
}}

Hey the answer to this question is A B C...as it is given that it is pass by value. But how can it be pass by value when the string reference is passed as the argument. When we pass the object reference isnt it pass by reference?

Hi naresh,
Thanks for the info..I will buy the book today

Hi sasi,
These are the doubts i got after studying threads from khalid mughal

Hi all,
Just a few queries in threads

1. What is the difference between sleep(long) and yield() method(arnt both doing the same task of giving a chance for other threads?)

2. Consider the following code

class A{
synchronize meth(){}
synchronize meth1(){};
}

can we call meth() and meth1() on the same thread ie say t.meth() and t.meth1() simultaneously ie can we call these methods with the same object reference?



3. When a static method is synchronized and is called, can synchronized methods of instance methods of the same class be called at the same time? Or are they mutually exclusive?(as static locks the entire class)


4.for synchronized blocks what does this mean.
synchronized(<object reference>

does this mean that the thread should first acquire lock on the object of object reference before we enter the blocks code?

Hi all,
I am new to java ranch and got really annoyed when most of you wrote that we should follow k&b as i read only khalid mughal. Is khalid mughal sufficient to get 90+ or should i go through k&b also?

Thanks

String s=new String("hai");
String s1="hai";
String s2="hai";

Just for your info, here only 2 objects and 3 references are created. s1 and s2 are string references which point to the same object "hai"
whereas s references a new "hai"

If it is a scjp voucher plz , i am ready to take
