Groovy

The Groovy project is a dynamic and agile language for the Java 2 Platform, which has many of the features that people like so much in languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax.

Groovy is designed to help you get things done on the Java 2 Platform in a quick, concise and in a fun way.
