I am using java 1.2.2. and jaxp 1.1
and trying to run the demo program came iwth jaxp-1.1.zip
program compiles properly but give following runtime error
PATH and CLASSPATH set properly.

C:\jdk1.2.2\jaxp-1.1\examples\SimpleTransform>java SimpleTransform
A nonfatal internal JIT (3.10.107(x)) error 'Relocation error: NULL relocation
target' has occurred in :
'org/apache/crimson/parser/Parser2.maybeComment (Z)Z': Interpreting method.
Please report this error in detail to http://java.sun.com/cgi-bin/bugreport.cgi

I have reported this to sun.com also.
will somebody give soluation for this problem.

Dear Leena,
The reason is that, Java uses UNICODE for representing charachters internally, but uses UTF for IO.
UTF means UCS Transformation format
and UCS menas Universal charachter system.
UTF uses 1 or 2 or 3 bytes to represent charachter in IO
and all ASCII char's requires 1 byte only.
Thats why answer is 4 bytes.

I am new to XML. Can anyone tell how to start with XML.
and where I can get good XML FAQ.

Dear friends,
I had given SCJP2 exam on 9th June, got 96%.
When I finished my exam, I was expecting result 85 - 88 %. But when lady there processed the result and taking printout, initially I thought I will not ask result till she don't give me printout, but I couldn't wait, I asked that lady, what's the result, she coolly said, 96%, I was shocked, said CAN'T BELIEVE. It is very happy and satisfying moment for me, which I want to share with you.
Out of 59 I got 57 correct, lose 1 in Threads and 1 in Flow Control & Exceptions.
I am very much thankful to JavaRanch, Moderators, participant of discussion forum. I must tell that, I could get such good score due to JavaRanch only. The discussion here gave me good information and tricks of exam. And most important is that JavaRanch helped me lot in keeping my motto for exam.
Initial 5-10 questions were easy. So I was feeling comfortable. Then I got some tricky questions on Flow control, language Fundamentals. In total I got 60-70% questions as single answer, and rest as multiple choice questions. And one question was fill-in-answer type.
During my practice of mock exams, It was my experience that, once I finished test, I was reluctant to review the answers, and If I do review, I couldn't catch the wrong answer, because I used to think on same line.
Thats why I had given more time for solving test. I finished 95 mins, and I got 25 mins for review. I had marked 15-18 questions. I had coolly revised those, and I found 4-5 answers were wrong, I changed those.
Initial I used Robert, Hieler's book (RHE), then I used Moughal Khalid's book. I found these both books very helpful. I also used Velmurugan's notes, which helped me lot in last day preparation and revision.
Believe me, SCJP2 exam is not that hard which I used to think.
Once again thanks to JavaRanch and participants.

Dear friends,
After 4-5 months of practice, I am taking Exam on 9th June.
Now only 2 days are remaining. I am quite confidant but somewhat tense. I am getting various mock exam score in the range of 85 - 90%
Lets see what happens.
I will let you you know about result.
Regards,
Sujit

I agree with Sona and Others who says 3 objects will be eligible for GC.
d = c = b = a;
After this, reference count of Object, orignally refered by Object reference a, will be 4. and other 3 will be eligible for GC.
and,d= null; will only reduce the reference count of Only remaining object by 1, and new reference count will be 3.
Sujit

Reason for this is also same as for while loop.
if(i==3)
int p = 3;
compiler is unable to determine the scope of variable p.
if(i==3); This prefectly OK, since it has empty statement.
int p;
if(i==3) p = 4; This is also prefectly OK

I am from Pune and appearing for SCJP in 1st or 2nd week of June.
Anybody from pune also appearing.
Sujit

System.out.println("Result = "+o1 == o2)); // Prints False
Object o1 = new Object();
Object o2 = o1;
System.out.println(o1 == o2); // Prints True
System.out.println("Result = "+o1 == o2); //prints false
It is similar to,
String s1 = "Result = "+o1.toString();
System.out.println(s1 == o2);
Correct me if I am wrong.
Sujit

It is obvious thing which can be make out from code,
can I confirm it from API,

Refering to Object Ref casting rules given in RHE fig 4.10 page 121.
old-typeNew-typeRule as per RHEDoubt 1.Non-final ArrayNew type must be objectArray is Object, classbut Object need not be Array 2.final classArraycompiler errorIt should be same as 1 New type must be object 3.Interfacefinal-classa. new type must implementOK old type b. or SerializableCan't understand 4.InterfaceArraycompiler errorCan't new type be Object 5.ArrayInterfacecompiler errorCan't new type be Serializable or Cloneable
Looking for explaination on these points.
Thanks in advance.

Dear Hima,
Hearty Congratulations !!
You have great achievement.
Sujit

Given :
Object x[] = new Object[10];
Serializable q1 = x; // 1 OK
Cloneable q2 = x; // 2 OK
How this code compiles without problem.

Dear Ravindra & Mikael,
Thanks for reply, Its clear to me now.
Sujit

Hi Ravindra,
I got something, but still some doubt;
i= i++; // first assigns the variable ie. 'i' is assigned '0' and later incremented but by assignment it assigned '0'. i.e., i even was incremented but due to assignement to the same variable got overwritten by '0'on successive operations too it assigned '0' first and then increnmented this will happen endlessly and hence the output will be '0' ALWAYS
Refering to your reply to same question earlier.
i = 0;
i = i++; //1
i = i++; //2
You said, since it is post increment operator, first 0 will be asigned to i at line 1, and don't it perform ++ operation.
If so, after end of line 1, value of i should be 1.
Whether ++ does get executed or not ?
