Best online resources for learning Java 6 from Java 4 background?

Our company is finally coming out of the dark ages and embracing Java 6. We have been using Java 4 for many years and I'm interested in learning the new features offered by Java 5 and 6. So, can anyone recommend any online resources to help me learn what's new since Java 4?

Just as a clarification, you mean that you currently use JDK 1.4.x right? I think Sun's marketing machine when from Java 1.0 Java 1.1 Java 2 ( 1.2 , 1.3, 1.4) to Java 5 (1.6) and finally Java 6 (1.6). I never heard of "Java 4" in the Sun literature. I agree that : http://java.sun.com/j2se/1.5.0/docs/relnotes/features.html give a nice summary from the horse's mouth

Except for generics, most everything there is to learn can be done incrementally. Nothing in Java requires you do something the new way. Start with enhanced-for, autoboxing, varargs and formatted printing.

With generics, read up on an overview, say Angelika's FAQ, and then begin applying generics bit by bit - be prepared to invest some time for the more complex generics programming.

Have a look at the New Features of JDK 1.5 from the Java 5 & Java 6 Tutorials (at coreservlets.com) for a quick overview:

All the material in this section is covered in more detail in earlier sections. But, if you are a real old-timer and only know Java 1.4 or earlier (Gasp! How 20th century!), this section might be useful for you.

  • This tutorial section in PDF.
  • Topics covered:
    • The for/each loop
    • Scanner and command-line input
    • Generics
    • Autoboxing
    • Varargs
    • printf
    • Reading command-line input

Also check the Java Language Features in the New Features and Enhancements of J2SE 5.0.

The main changes to the language it self were introduced in the Java 5 release.

These include:

  • generics
  • enchanced for loops
  • var args
  • autoboxing

and a number of others

Here's an interesting article with examples:

Java 6 changes were most on performance and new APIs you should start with the changes in 5 first
