Because Groovy is so new, most readers will be learning it from scratch.

Groovy In Action quickly moves through the basics of Groovy. After getting readers up

and running, Groovy in Action presents rich and detailed examples illustrating

Groovys enhancements to Java along with Groovys special support for XML,

regular expressions and database programming. Readers get their hands dirty

exploring tips and tricks for Groovy programming along with core tasks such as

unit testing and build support. Readers will even learn to script Windows via

Groovy. An additional bonus track is dedicated to Grails, the Groovy Web

Application Framework.

Groovy in Action introduces Groovy by example, presenting lots of reusable code

while explaining the underlying concepts. Java developers new to Groovy find a

smooth transition into the dynamic programming world. Groovy experts gain a

solid reference that challenges them to explore Groovy deeply and creatively.
