Language Books/Tutorials for Groovy [closed]

Answer 1

Shameless plug: I'm one of the co-authors¹ of Groovy in Action, which is pretty well regarded in Groovy circles, as far as I'm aware.

There's a second edition in progress - if you order that now, you get early access to the second edition ebook as it's written, and a full copy of the first edition ebook to be going on with.

That said, of course there are plenty of other books around Groovy - with some particularly focusing on one area, such as Grails.

¹ Actually I'm more like a glorified editor. While I've touched large portions of the text, I've written very few complete paragraphs, if you see what I mean.

Answer 2

Here's the obligatory Project Euler link, which is a petty universal means of familiarizing oneself with a new language. The problems are not ideal for learning the more macro aspects of programming ( OOP, Design Patterns, etc), but it will give you a good feel for Groovy's syntax and basic features. I've ground through just shy of 100 of them, with definite results. - Plus, it was fun.

I'd also recommend the Groovy Web Console. You can use it to run your scripts online, but perhaps more importantly, you can browse the scripts of others - I've found this to be rather invaluable, particularly while getting acquainted with Groovy's DSL capabilities.

Answer 3

If you're looking for online tutorials, I recommend reading the Practically Groovy series by Andrew Glover and Scott Davis, as well as the Groovy Goodness snippets by mrhaki which all provide plain, helpful and mostly up-to-date information about the important and pleasant language features.
