Hi, First If you want to start simple and build from there.

I would start with "Beginning Programming with Java for Dummies"
by Barry Burd, (Paperback - 2003).

From there go deeper with two books,
Java in a Nutshell, Fourth Edition
by David Flanagan (Paperback - 2002)
& 
Java Examples in a Nutshell, 3rd Edition
by David Flanagan (Paperback - 2004)

Finally, to get more expert and advanced training try

Core Java(TM) 2, Volume I--Fundamentals (7th Edition) (Core Java 2)
by Cay Horstmann, Gary Cornell (Paperback - 2004) & Core Java(TM) 2, Volume II--Advanced Features (7th Edition)
by Cay Horstmann, Gary Cornell (Paperback - 2004)

Finally, check out the Sun Certified Programmer & Developer for Java 2 Study Guide (Exam 310-035 & 310-027) and take the Sun certification
by Kathy Sierra, Bert Bates (Paperback - 2002)

Good Luck!

Absolutely The Best Book to Start With:

"Head First Java" by Sierra and Bates  (published by O'Reilly)

I used this to learn Java, and learn it well.  It teaches you not only Java syntax, but OOP in the best, most effective way I've ever seen (and I've read a lot of books...)

It's done in an engaging, easy to read style that keeps your attention, makes you think, and gets your to really internalize the lessons.  Hands down your best bet for learning Java.  

Ok - I'll stop before I start sounding like an advert for the Head First series...  ;p

Seriously, though, this is one book you cannot afford to miss if you want to learn Java.  It is THE perfect starting point.

My personal favourite is "Java how to program" by Deitel & Deitel, now in the fourth edition (I think). I realyl believe it is the best Java book for beginners there is.

I used to read some books such as Java How to program , Thinking in java , Effective Java , Java in a nutshell ... I'm not a beginner :) I want to become an expert :) . I knew some technologies on java such as RMI , Java Beans , JDBC , EJB , JSP , Servlet . I want to know more about Java :)

Well, whatever books you choose, don't overlook the Head First series.

There's another one about JSPs and Servlets out now.

I don't care about JSPs or Servlets.  I write C for *nix.  But I bought the $50 book just because the teaching style is so damn good!

You may be an intermediate wanting to be an expert, but I guarantee you, you WILL learn something from Head First Java.  Something good.  Something that will enhance your skills as a coder, and your overall understanding of programming in general.  They really are that good.  Seriously, see if you can't find a used copy on Amazon or something.

P.S. No, they're not paying me.

P.P.S Yes, I *do* deserve for them to pay me after this shameless plug...
