Apache 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, is dynamically compiled to Java virtual machine (JVM) bytecode, and interoperates with other Java code and libraries.

Example from Riju:
print "Hello, world!";
Example from hello-world:
println "Hello World"
// Hello World in Groovy println "Hello World"
Example from Linguist:
#!/usr/bin/env groovy println "Groovy!"
Example from Wikipedia:
class Bird implements FlyingAbility {} /* Adds the trait FlyingAbility to the Bird class capabilities */ def bird = new Bird() /* instantiate a new Bird */ assert bird.fly() == "I'm flying!" /* the Bird class automatically gets the behavior of the FlyingAbility trait */
