Introduction to Groovy and Grails

     Groovy is a dynamic scripting and programming language for the Java platform. It combines the dynamic features of modern scripting langauges such as Ruby and Python with familiar Java syntax. To quote one of the Groovy developers: “Groovy is what Java would have been if it had been created in the 21st century.” This course introduces the Java developer to the Groovy langauge. The course focuses on understanding the internals of how Groovy works in addition to understanding the Groovy language syntax. After taking this course developers will understand the Groovy syntax and be able to leverage existing Java classes within Groovy. This class combines lecture with a unifying, hands-on experience, and open discussion that will help the developer quickly understand the benefits of Groovy and how to use the language.
