What coverage is there of Java 6 (and previous versions) classes vs those classes/libraries new in Java 7?

You can start with this. It covers the new features in Java 7.

Um, I think this is a question about the book, Java Programming, which is currently being promoted in this forum. I don't know the answer, but perhaps the book author can help.

Ah if that is the case then, the Java 7 features have been covered as and where required.

How does this book address super beginner java developers. I come from php background, but have interest in java and am planning to take SCJP. I had to read and re-read to get the basic understanding of concepts and also had to refer multiple resources..

Than you

As pointed out by Mohamed, the book covers Java 7 features as and where required with elaborate examples. It does not make sense in putting all new features in one place and that is why those are distributed at appropriate points throughout the book.

The book should help you find lots of information required for SCJP in one place and with the technical accuracy that is absolutely essential in answering SCJP questions.

i find that interesting. i learned java first. when i later read a book about php it seemed almost as familiar as an old hat. very much like JSP

Not sure if this is off topic or not but,

when is the proper time to move to Java 7? I noticed it is still not available for general download. Somehow I had the impression it should release last autumn. Anyway, it's possible to download both the JRE and JDK.
- Would it be risky to start developing with Java 7 now?
- Are there any known pitfalls?
- What about deploying applications written in Java 7?

It isn't?

Since you're plainly conversant with 6, what was your (or your company's) thinking regarding that?
For personal use: I'd regard any non-beta release as worth downloading.
For production code: Dunno. You might deploy it for non-critical systems first; particularly if you have a system (such as Solaris 10, or some of the latest Linux releases) that allow you to run them in a different VM (OS VM that is).

I checked java.com earlier today and was still only offered the latest version of Java 6. I checked again now and guess what! Java 7 is out there. That probably means my main question is not as relevant any more.

Check out http://en.wikipedia.org/wiki/Java_version_history. There have been several updates to Java SE 7 since its release on July 07, 2011.
 
I agree. Here's the link: http://aspose.com/file-tools
