GV110: Groovy Workshop (1-2 days)

Workshop Overview

This workshop is aimed at developers (in particular Java developers) who wish to learn about the Groovy language. Groovy's goal is to bring lightweight, agile, and dynamic programming to the Java world.

Groovy encompasses powerful features as known from Ruby, Python, Scala, PERL and Smalltalk in an expressive and intuitive syntax while keeping the view and perspective of a Java programmer. Its seamless integration with Java makes it a perfect solution for enhancing your current Java projects with dynamic behavior. It's built-in testing and mocking facilities make it ideal for agile development teams wanting to boost their testing productivity through a dynamic language.


Software Developers, Testers, Designers, Technical Managers and Architects interested in understanding the role dynamic languages (and Groovy in particular) play and how they can be used effectively during agile development. Attendees will come away with an example-rich exposure to Groovy and will be able to start using Groovy in their own workplaces.


Attendees should have some previous exposure to the Java programming language or exposure to Ruby or another scripting language.
