Good Java books?

[Shockwave]

I am really enjoying this book, it's gentle and at the same time really informative, I would reccomend it to any would be OOP programmers too.

I've always been frightened off OOP by the complicated development environments, this book takes the sting away from it by using a simple IDE so you can worry about using netbeans or eclipse later once you've grasped the language

[JL235]

There is another learning IDE that the same guys have built called Greenfoot. It's a nice environment and now comes with it's own book too (some of my source code is in that book).

Like the BlueJ environment, the Greenfoot one does a lot of work to make programming easier and simpler. Only this time it provides a visual world you can add objects too and then interact with. As a result it's more games related then BlueJ, but if you have Objects First then I don't think you'll find the Greenfoot book as useful.

I don't really want it for games to be honest mate.

After I have gone through this book I'll have to learn Eclipse because that's what they are using in work.

Yay! My first class...

I know it's simple..

welldone nick and keep going :0)

@Shocky:
Congratz for your first class. Nice to see that it is a heater (fits to
the current season). Most "first classes" are something like dog class
(private field name, public method bark()).

One minor cosmetic hint though, I would recommend to start
a class name with a capitalized letter.

Well, but thats minor stuff ... Keep it going!

Seconded.

You could also take a look at JavaDoc for generating the class documentation.

But keep it up.
