yes. it's by far the best series of books I've encountered for those certifications.
Oracle changed the name of the certification, not the contents. of course, if you 'll go for the Java 7 exam, you should also look into the new material, but for Java 6 exam, that book is what you want . (and the material for Java 7 isn't that much different)
of course a lot depends on whether you know Java or not... The book assumes you do, a lot of punters try to get through the exam who don't, and just want some cram sheet and "the dumps", which this book will not provide you with.
