I'm a student from India who aspires to give the SCJP/OCJP exam this year. I'm extremely confused regarding the current version of the exam ie Java 6 or Java 7. Also I have purchased the SCJP java 6 study guide by Kathy Sierra and Bert Bates for this exam. Could you please tell me if this book is sufficient for the preparation of the current version of the exam. Also could you please highlight any change in the exam pattern than the one mentioned in this book. Your help would be appreciated.
