Groovy is ...

Section

An agile dynamic language for the Java Platform with many features that are inspired by languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax.
Developing web applications , writing shell scripts easily, writing concise, meaningful, test cases using Groovy's JUnit integration, or prototyping and producing real industrial strength applications have never been so concise and groovy.

Groovy works cleanly with all existing Java objects and libraries and compiles straight to Java bytecode in either application development or scripting mode.

A simple hello world script:

Code Block

def name='World'; println "Hello $name!"


A more sophisticated version using Object Orientation:

Code Block

class Greet {
  def name
  Greet(who) { name = who[0].toUpperCase() + who[1..-1] }
  def salute() { println "Hello $name!" }
}

g = new Greet('world') // create object
g.salute() // Output "Hello World!"


Leveraging existing Java libraries:

Code Block

import org.apache.commons.lang.WordUtils

class Greeter extends Greet {
  Greeter(who) { name = WordUtils.capitalize(who) }
}

new Greeter('world').salute()


On the command line:

Code Block

groovy -e "println 'Hello ' + args[0]" World
