Hi Larry,

Thanks for your response.

I have already verified the my mailing address at certmanger.com/sun. They have mailed me the certification THRIECE- But all the times, I haven't received the certificate. As I have provided my Oracle office address as the mailing address, I am sure that it hasn't missed at my end.

I dont understand why Sun can't take some more money from us and send the certificates via registered post, so that we can track the couriers.

As it has been 5 weeks now after they have sent the THIRD ceritificate, I am now puzzled what to do next? (already mailed to the mailing list)

Thanks & Regards,
Harish

Hi,

I have taken SCJP exam on 17-NOV-09, but still I haven't received the certificate yet. I have been following up with the sun certification support team. They have dispatched the certificate twice, but I haven't received any of them. I am from India.

Is everyone facing problems with receiving SUN certificate? Is there any better way to handle this situation?

Thanks,
Harish

Hi,

I observed that Outer classes can access inner classes private instance variables. How is this possible? A sample code demonstrating the same is explained below::

class ABC{ class XYZ{ private int x=10; } public static void main(String... args){ ABC.XYZ xx = new ABC().new XYZ(); System.out.println("Hello :: "+xx.x); ///Why is this allowed?? } }

Can any one explain why this behavior is allowed?

Thanks & Regards,
Harish

Thanks everyone for the wishes

Hi,

I have just cleared SCJP exam and planning to SCWCD next. I am having around 2 yrs experience in developing applications involving JSP & Servlets.

Can any one kindly suggest which book will best suite me to prepare for SCWCD exam?

From SCWCD links, I could find the below books ::
1. First Edition - Head First Servlets & JSP by Bryan Basham, Kathy Sierra, Bert Bates
2. Second Edition - Head First Servlets & JSP by Bryan Basham, Kathy Sierra, Bert Bates
3. Sun Certified Web Component Developer Study Companion (1st Edition) by Charles Lyons
4. Sun Certified Web Component Developer Study Guide by David Bridgewater
5. SCWCD Exam Guide with Java EE 5 by Kunal Jaggi.

Please suggest me best book which suits me(either from the above list or any other book)

Thanks,

Hi,

I cleared SCJP with 88%.

I am very thankful to Kathe & Bert for their excellent SCJP book. That is the sole preparation material you would ever need for SCJP exam.

Just make sure that you have gone through the whole contents and have taken all the questions at the end of each chapter along with 2 mock tests.

Also I am very thankful of Devaka for his excellent ExamLab software. It exactly replicates the prometric testing center software.

Just make sure that you atleast one test from ExamLab http://scexamlab.net78.net/. It will make you feel comfortable while taking the real test. Also the questions are very good (as usual at higher level than SCJP). Of course if you take all the five tests that will make you better prepared for the exam.

Also thanks to everyone in this forum for responding to my posts while preparing for SCJP

Thanks,
Harish

Jacquie,

Thanks for writing such nice book.

After reading various responses on this post about the book, I am excited about it and got a feeling that it will surely address some of the situations which we could face
I will certainly go through it.

Thanks Mike for the confirmation. I will try to inform the authors to make this correction, as it could confuse newbies.

Can any one please let me know how can I intimate SCJP 6 authors (Kathy / Bert) regarding this correction? Is there any separate group for that in this forum?

Hi,

I am going through SCJP 6 book by Kathy Sierra & Bert Bates. A sample code snippet is given below from Threads chapter, where I need a clarification
synchronized(a){ //The thread gets the lcok on 'a' a.wait(2000);// Thread releases the lock and waits for notify only for maximum of two seconds, then goes back to runnable state //The thread reacquires the lock //More instructions here }

Now my doubt is, after 2 seconds of wait time, to continue further code execution, the above code would require the lock on object 'a' and there is fair chance that the other thread (which is supposed to call notify() on a) might already be holding a lock on it.

So shouldn't the thread go to Blocking state after 2seconds wait, instead of Runnable state as mentioned above in the comments (in Line No. 2).

Kindly clarify what am I missing here.

Thanks & Regards,
Harish

Thanks for the both of the responses.

Prashant,

Yes I am currently using 32 bit JVM. I will try to execute the code if I get hold of any such processor.

Thanks,

Hi,

I am aware that if you are assigning int to a byte without any implicit cast, then the int should be a compile time constant and value should be in byte range.
i.e. the below code compile fines.
final int b = 10; byte a = b; // compiles fine

But if I try the same thing with long, it fails.
final long b = 10; byte a = b; // Doesn't compile !!!

Why is that compile time constant of type int can be assigned to byte without any implicit cast, but we cannot assign compile time constant long to byte?

Thanks,
Harish
