Hi Jay,
I think it is looking for last CCC element, from which BBB obviously is preceding sibling.
<AAA>
<BBB>
<CCC/>
<DDD/>
</BBB>
<XXX>
<DDD>
<EEE/>
<DDD/>
<CCC/>
<FFF/>
<FFF>
<GGG/>
</FFF>
</DDD>
</XXX>
<CCC> <------ last CCC Element
<DDD/>
</CCC>
</AAA>
Please corect me if I am wrong.

Thanks,
Arun

Hi Jayadev,
I agree with you. It would be very nice if JR guys can provide space for XML reference book.

Hi,
I had also same problem . It would be very helpful for us, if someone can point out different url for XML reference.
Thanks,
Arun

Hi,
Following question is taken from JWeb+.
A servlet implements MultiThreadModel interface. The servlet container may run multiple threads on its methods. True False
I have selected "False" as there is no such MultiThreadModel, but the answer is "True".
The explaination for that is:
MultiThreadModel is not a standard interface. It may be a user defined interface and in that case, the given statement is correct.
Could someone please explain it.
I just wonder if such type of questions that might have double answer will be in the real exam.
Thanks,
Arun

Thanks

Hi all,
import java.util .*; public class TestClass { public static void main(String args[]) { Stack s1 = new Stack (); Stack s2 = new Stack (); processStacks (s1,s2); System.out.println (s1 + " "+ s2); } public static void processStacks(Stack x1, Stack x2) { x1.push (new Integer ("100")); x2 = x1; } }
Could someone please explain, why the answer is [100][] ? I think it should be[100][100] as the parameters for the methods are Object.
Thanks,
Arun

If raf is a RandomAccessFile, what is the result of compiling and executing the following code? raf.seek( raf.length() ); [a] The code will not compile. [b] An IOException will be thrown. [c] The file pointer will be positioned immediately before the last character of the file. [d] The file pointer will be positioned immediately after the last character of the file. [e] None of the above
Hi,
The right answer is [c] but I think it should be [d]. Please help me to understand this problem.
Thanks,
Arun

Why s=b*2 does not work like s=(short) b*2 ?

Hi all,
Why does s+=i; compile correctly but s = b*2;
does not ? Given short s=1; byte b=1; int i=1;
I think in both case right operands prometed to int. Isn't so ?
Thanks
Arun
