  1. Sam says:

    Good post! Its pretty neat for a quick recap of which feature showed up in which release :)

    I didn’t quite catch a few of the feature.

    Whats Automatic Null Handling in Java 7? Do you mean the Elvis operator? It was proposed as part of project coins, but wasn’t implemented in Java 7.

    Also whats the difference between Type Inference for Generic Instance Creation and Diamond Syntax?

  2. Rajeev says:

    very nice post!
    It’s a quick revise of java features.

    Thank you!

  3. John says:

    thank you Joe,I refered your blog for easy reference when I prepared for an interview.Now I am regular reader of your blog. But you should post more often,like once in a week or so.

  11. surendra8 says:

    nice share ..

  12. Anders says:

    Java SE 7 referens implementation is not Sun/Oracles any more, it’s OpenJDK. I guess that might be important em enough to be in this list. Oracle has changed the license so it can’t be redistributed in binary form by others any more. That is why Sun JDK will be removed from all distributions in the future.
    Use OpenJDK instead.
