Video description

Discover the simplicity and power of Groovy.

Groovy is a powerful, multi-faceted language for the Java platform that integrates smoothly with any Java program. In this Learning Path, you'll see how writing anything—from a simple build script to a full-scale application—is much easier with Groovy than with Java. Discover the many advantages of adding Groovy to projects written in Java and other object-oriented languages.
