In kathy and bert certification book it is mentioned there is 49 keywords and identifiers. I was going through Complet Java 2 Certification - Philip Heller and Simon Roberts book it says 52 keywords including "false, null and true" which is right!...
Thank you for the reply.

Simply put, there are 52 reserved words in java, 49 of them are keywords and the remaining three (true, false, null) are considered literals.
