How to create a collection/array in size N with each cell initialized to zero in Groovy?

Question

Is there a short way to create a collection/array in size N with each cell initialized to zero in Groovy? Can't seem to find it on http://groovy.codehaus.org/JN1015-Collections

For example

arr = func(3)  

would result in

arr = [0, 0, 0]

Answer 1

Yep, the Collection#multiply (or *) method:

assert [0] * 3 == [0, 0, 0]
