Hi Amit,
The Indian fee for
SCJP exam is 7000/-.There will be some centers which give this exam where you need to enroll yourself paying this amount.They give you an invoice along with the date of your exam.
Two excellent books for Sun Java Certification that you could use are:
1) Java 2 Certification Study Guide By Roberts and Heller , Sybex.
2) Java Certification for Programmers and Developers, by Barry Boone.
Regarding the contents you can refer to any of these two books you will come to know but what I can say is the basic fundamentals of java is asked in the exam and hey the passing score is 60% and time is 1hr 30 mins.
Hope this helps you.....
Regards,
Poornima.
