Create and iterate through an array in Velocity Template Language

Question

How to create an array in VTL and add contents to the array? Also how to retrieve the contents of the array by index?

Answer 1

Creating an array is easy:

#set($array = [])

Putting an element into an array is also easy:

$array.add(23)

Getting an element from an array depends from your Velocity version. In Velocity 1.6 you must use

$array.get($index)

Since Velocity 1.7 you can use the classic form:

$array[$index]
