问在Velocity中访问数组的最佳方式是什么？

EN

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

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

#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
