Differences between Java versions

Where can I find a resource that lists/discusses the differences between Java versions - specifically 1.2, 1.3 and 1.4 . I have some books and training materials for 1.2 and 1.4 (I find it easier to learn if I can read different explanations of the same topics). I want to make sure I ignore any 1.2 material which has been superceeded by 1.4.
Thanks, David

Sun's Java site ( is a good place to start. You can find current and past versions of the JDK, get documentation and work through good tutorials.
Here are a couple of good places to start:
Version 1.2 changes
Version 1.3 changes
Version 1.4 features
Happy hunting!
