Groovy: Spread the list elements

Using spread operator, you can spread the elements of a list.

HelloWorld.groovy

def evenNumbers = [2, 4, 6, 8]
def oddNumbers = [1, 3, 5, 7]
def primeNumbers = [2, 3, 5, 7, 11]

def allElements = [0, *evenNumbers, *oddNumbers, *primeNumbers]

println allElements

Output
[0, 2, 4, 6, 8, 1, 3, 5, 7, 2, 3, 5, 7, 11]
