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 including both members and the Manager of the Groovy Project team. The result is the true definitive guide to the new Groovy language.
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.
Because Groovy is so new, most readers will be learning it from scratch. Groovy in Action quickly moves through the Groovy basics, including:
Readers are presented with rich and detailed examples illustrating Groovy's enhancements to Java, including
Groovy in Action then demonstrates how to Integrate Groovy with XML, and provides,
An additional bonus is a chapter dedicated to Grails, the Groovy Web Application Framework.
Early PDF chapters of Groovy in Action are available from the Manning Early Access Program (MEAP) at "http://www.manning.com/koenig http://www.manning.com/koenig . As part of this program, readers can also discuss the early manuscript with the author and help shape the manuscript as it's being developed by joining the Author Forum.
