Groovy, the brand-new language for the Java platform, brings to Java many of the features that have made Ruby popular. Groovy in Action is a comprehensive guide to Groovy programming, introducing Java developers to the new dynamic features that Groovy provides. To bring you Groovy in Action, Manning again went to the source by working with a team of expert authors includin...more

We are using Grails at work. I am using this book as a reference, looking up topics as needed and leafing through it to get a general feeling for the language. Groovy is a lot like Ruby, but with a syntax that is much closer to Java.
I was looking up the -p and -n options to write scripts for processing input files, and I was annoyed that there was no exhaustive list of the resources available to my script as it processes lines. The book mentions line, which holds the current line, and count that...more

Groovy is turning out to be rally rather interesting.
I remember thinking that I was learning OO back in the 90's and reading GOF patterns Design Patterns book and not really getting the plot. Why did they need Visitors, Observable and Action Listeners. What was it all for?
I understood this later when working with various Java frameworks and was really quit impressed with the GOF's foresight.
Groovy strikes me as this story being repeated. The way that Meta Class Dispatching and Closure can be com...more

This is a well-written and fun book by the creator of Groovy that allows one to quickly start working in the language.
Why would one want to learn Groovy? Groovy is an extension to the Java programming language that allows one to write simple scripts that are Perl-like in flavor. Suddenly Java no longer feels like a compiled language. Classes may be mutated on the fly: one can add fields and methods during execution. The code is concise, clean, and intuitive. Groovy includes powerful integration...more

The Good:
This book will teach you Groovy
The Bad:
I thought that the first part of the Book (which teaches you the Groovy Language) was verbose and could have been better organized.
Conclusion:
If part 1 of the book (covering the Groovy Language) had been more concise and better organized I would have rated this book 4 stars. Also, if you are going to buy this book be advised that at the time of writing this review (June 27, 2011) the second edition of the book is available as a preview from the pu...more

Groovy is a new programming language, that is based on Java, but has optional dynamic typing. Groovy also borrows features from Python and Ruby. The examples in this book appealed most to me. Even if, after reading this book as a Java developer, you still want to stick with Java, you would have learned just as much about Java as from any Java book. Groovy is after all very similar to Java.
I don't find this book to be very practical or well organised, although it does give you a lot more background knowledge about groovy than some of the other books. I would recommend "Groovy Recipes" if you want to see groovy in practice.
I'm starting a new Java project that promises to be large and complex. It seems that using Groovy may provide big benefits, so I'm trying to read about it as quickly as possible. So far, this is a very easy and informative read.
Great book on a great language!
- it's kind of old, it's for Groovy 1.0, hope to see second edition soon
- Good reference for groovy language. Hope to see groovy make it to top 20 language.

This is still probably the best overall Groovy reference available. It has tons of great information that is hard or impossible to find on the web, and it covers everything from simple, command-line scripting to building web apps with Grails.
Enjoyed the way all code examples were written using asserts.
I'm beginning to hate Java less, thanks to Groovy.
