Groovy is an object-oriented programming language for the Java platform.

It is a dynamic language with features similar to those of Python, Ruby, Perl, and Smalltalk. It can be used as a scripting language for the Java Platform.

Groovy uses a Java-like bracket syntax. It is dynamically compiled to Java Virtual Machine (JVM) bytecode and interoperates with other Java code and libraries. Most Java code is also syntactically valid Groovy.

Groovy 2 was released on June 28, 2012.
