Fluently Groovy

This tutorial is for Java developers unfamiliar with Groovy,
who want a quick and easy introduction to the basics. Get started with Groovy's
simplified variation of the Java syntax and learn about essential features like native
collections, built-in regular expressions, and closures. Write your first Groovy class,
and then see how easily you can use JUnit to test it. You'll walk away from this
one-hour tutorial with a fully functioning Groovy development environment and the skills to use it. Best of all, you'll have learned first-hand how to use Groovy and Java code together in your everyday Java application development.
