Hi guys,
Does anyone know how to change the color of the scrollbar of the select menu(drop down menu)?
I could change the color of the scrollbar of the body page but not the select menu.
Thanks in advance.

4.3 - 2.3 is promoted to double and so is calculated as 4.3d - 2.3d
float and double arithmetic is full of tiny inaccuracies due to the way the numbers are stored internally and limiting precision.


Thanks for the answer,
I have checked double always give precise answer but if you have substraction with float it does not. The inaccuracies are only in float, I think.
Any comment?

Why these two statements give different result?
System.out.println(4.3 - 2.3);
2.0
System.out.println(4.3f - 2.3f);
2.0000002
I mean why there is .0000002
Can anyone explain?
Thank You

Dear Tariq,
They were 4 to 5 questions on this topic. I don't know any good tutorial for this one. I got 87% in this field by using material I mentioned before.

Congrats Rishi- So what books did you use for preparation and how long did you prepare for the exam. We would love to read your experience....


Dear Louis,
I used professional JSP by wrox. I prepared this test for 10 days. I did not use any book for servlet (just for Ken's and Sun's spec a bit). And more thing about questions, I have to realy give thumbs up to Sun. They have made most of the questions in a such a way that you really have to experience JSP and Servlet to be able to answer the questions.

Dear Tariq,
What I can remember is the questions were spread equally for each section in objective. Sometimes they combine 2 or 3 sections in one question. For example there is a question about bean combined with the custom tag and tag library.

Hi,
I just passed. The exam was more difficult than I taught.
I used Ken's notes. I have experienced JSP for 6 months and Servlet 1 month. This is not enough. Don't think that if you memorize the specs you can get good score. Probably you can pass.

Hi guys,
Is it ok if I don't specify -Djava.rmi.server.codebase when I run it?
Will I lose mark?
In my spec it says that I have to provide documentation for database server. What kind of doc do you guys provide?
Thanks in advance
