So what is Groovy? Groovy is like a super version of Java. It can leverage Java’s enterprise capabilities but also has cool productivity features like closures, builders and dynamic typing. If you are a developer, tester or script guru, you have to love Groovy. Below are some of it’s features.
- Is an agile and dynamic language for the Java Virtual Machine
- Builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk
- Makes modern programming features available to Java developers with almost-zero learning curve
- Supports Domain-Specific Languages and other compact syntax so your code becomes easy to read and maintain
- Makes writing shell and build scripts easy with its powerful processing primitives, OO abilities and an Ant DSL
- Increases developer productivity by reducing scaffolding code when developing web, GUI, database or console applications
- Simplifies testing by supporting unit testing and mocking out-of-the-box
- Seamlessly integrates with all existing Java objects and libraries
- Compiles straight to Java bytecode so you can use it anywhere you can use Java
A simple hello world script:
|
1 |
def name='World'; println "Hello $name!" |
A more sophisticated version using Object Orientation:
|
1 2 3 4 5 6 7 8 9 |
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:
|
1 2 3 4 5 6 7 |
import static org.apache.commons.lang.WordUtils.* class Greeter extends Greet { Greeter(who) { name = capitalize(who) } } new Greeter('world').salute() |
