Summary
Introduction to Groovy is a three day in-depth course geared for Java developers who need to understand what Groovy is and how to use in with today's systems and architectures. Groovy is a dynamic scripting and programming language for the Java platform. It combines the dynamic features of modern scripting languages 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 language. 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. This class is “technology-centric”, designed to train attendees in essential Spring and Hibernate development skills, coupling the most current, programming techniques with the soundest industry practices. This workshop is about 50% dynamic lab exercises and 50% lecture. Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review. Multiple detailed lab exercises are laced throughout the course, designed to reinforce fundamental skills and concepts learned in the lessons. At the end of each lesson, developers will be tested with a set of review questions to ensure that he/she has fully understands that topic.
