London Java Community:Groovy for Java Developers
Groovy for Java Developers
In this session, Russel Winder provides a great introduction to Groovy. His aim is to convince you that if you want a language other than Java, all you need is Groovy. After a brief introduction to the origins of Groovy and its main purpose, Russell introduces the main parts of Groovy that make it such a useful dynamic language.
Groovy is a dynamic language for the Java Virtual Machine. Its aim is to build on the strengths of Java to provide a dynamic language with additional powerful features. It includes often sought after features such as support for Domain Specific Languages, unit testing, mocking and integrates with existing Java objects.
Russel uses the basic hello world program to illustrate many of the powerful features incorporated in Groovy. There is also a very useful discussion on the invoke method within Groovy, how it can be used and how it can be a very confusing function.
This talk is a great place to start for anyone interested in using Groovy. Russel describes many powerful features of Groovy but never loses sight of the fact that Java still has many purposes and the two can be used powerfully together.
