OReilly - Groovy Fundamentals

Learn the advantages of using Groovy by itself and with existing Java projects. This video workshop takes you into the heart of this JVM language and shows you how Groovy can help increase your productivity through dynamic language features similar to those of Python, Ruby, and Smalltalk.
Presenter and Java consultant Ken Kousen demonstrates how writing anything from a simple build script to a full scale application is much easier with Groovy than with Java. You’ll quickly learn how to add Groovy to your projects, and then explore the language through a host of examples and demonstrations.
Once you complete this course, check out Ken’s other videos on the subject: Practical Groovy and Mastering Groovy.
