Here’s a lucid, fairly lengthy tutorial on Groovy, covering basic Groovy constructs with emphasis on comparisons with Java. The author admits that he won’t be getting too deeply into Groovy, that he is trying to give a more broad overview for people who are just starting to get familiar with Groovy code. Â It covers topics such as declaring classes, using scripts, GroovyBeans, Annotations for AST transformations, and quite a few other subjects, with plenty of code snippets included.
