Hi, The objective of scjp 1.4 is different from scjp1.5. The K&B book for scjp1.4 does not cover the topics in scjp1.5 objectives, otherwise it is the same. So if you are going to prepare for scjp1.5 it is better you get K&B book for java5. also the Self
test question differs in both the book. java5 test more on performance of the code than the language syntax. So it will be better if you get SCJP1.5 book of K&B or have to take extra effort to learn the new features of java5 from some other source.
