How to access elements of array after using string.split in Velocity?

Question

I am using Velocity Templating Language and currently have:

#set ( $stringList = $string.split(\",\") )

which works fine and splits the str

Answer 1

As of Velocity 1.6, all array references are now "magically" treated as if they are fixed-length lists. This means that you can call java.util.List methods on array references. So, if you have a reference to an array (let's say this one is a String[] with three values), you can do:

$myarray.isEmpty()

$myarray.size()

$myarray.get(2) 

$myarray.set(1, 'test')
