Effective Java or Effective Java: Programming language Guide

I want to update my core java develpment skills as I have done quit a bit of java programming in the past
up to ver. 1.3.

I heard Effective Java second editioin was the book to get but I also see
Effective Java: Programming language Guide.

I was wondering what the difference is between the too?
Which one is Better?
Which one I should get?

I am looking for best java practices and would like to get up to date with the new concurrency package and generics as well.

Thanks in Advance.

I think that Effective Java:Programming Language Guide refers to the first edition. Are they from the same author ? If yes, choose the latest one, the Second Edition (by Joshua Bloch).

Christophe is correct. Choose the one that does not have "Programming language Guide" as part of the title. If you look closely, the book cover should clearly say "Second Edition". Also it should be published in 2008, not 2001.

Michael,
The first edition called:
Effective Java Programming Language Guide.
The second edition called:
Effective Java , 2nd Edition by Joshua Bloch.
Yes get it, I have it and it is so precious.
