With the book being fairly dated, is it absolutely necessary I use such outdated versions of java and the api documentation? They are kinda hard to track down since the directions are outdated.

Anyone know what versions will work? or even better, links?

Thanks

Welcome to the ranch.

Java is backward compatible so using I later version of Java shouldn't be a problem. Your book won't describe the latest Java features but that's not a big problem whilst you are learning.
All the classes, methods etc described by the book will still be available in a later version of Java however there is an outside chance you may need to use something that is now deprecated but don't worry you can still use it, you'll just get a warning to say you are using a deprecated feature.

It's all very confusing and to make matters worse you also see java jdk. There have been various different names and usages of names over the years.
Java SE refers to Java Standard Edition as opposed to Java ME (Micro Edition) or Java EE (Enterprise Edition).
java sdk refers to a Java Software Development Kit which could be for any of the above.
j2sdk is essentially the same as java sdk, the j2 bit referring to Java 2 as Java version 1.4.2 was also called.

right now i have java SE dev kit 6 update 22

That should be fine to start with.

You may initially find the Head First Book a bit confusing since all the concepts are jumbled across the chapters. They don't go in the sequence in which a beginner should start off. Re read the chapters so that you get a feel of confidence that you actually are understanding what is in the book.
