Learn Groovy   

Lots of Groovy examples can be found at the Groovy home page, for example

Questions about Groovy can be asked in the JavaRanch Groovy forum.

An example

To start with, here are two versions of a short Groovy program that solves the first problem of Project Euler : If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.

def getSumOfMultiples = {def numbers, int max ->
    def allProducts = new TreeSet()
        int product = it 
        while (product<=max){
            allProducts << product
            product += it
    return allProducts.sum()

def getSumOfMultiples = {def numbers, int max ->

Both would be called using println getSumOfMultiples([3,5], 1000)
