What is the best way to access an array inside Velocity?

Question

I have a Java array such as:

String[] arr = new String[] {"123","doc","projectReport.doc"}; 

In my opinion the natural way to access would be:

 #set($att_id = $arr[0])  #set($att_type = $arr[1])  #set($att_name = $arr[2]) 

But that it is not working. I have come with this workaround. But it a bit too much code for such an easy task.

#set($counter = 0) #foreach($el in $arr)     #if($counter==0)         #set($att_id = $el)     #elseif($counter==1)         #set($att_type = $el)     #elseif($counter==2)          #set($att_name = $el)     #end     #set($counter = $counter + 1) #end 

Is there any other way?

Answer 1

You can use use Velocity 1.6: for an array named $array one can simply do $array.get($index).

In the upcoming Velocity 1.7, one will be able to do $array[$index] (as well as $list[$index] and $map[$key]).
