Actually, Velocity works with List objects, not Arrays.
#set($alist = {10, 20, 30, 40, 50})
#foreach($item in $alist)
$item
#end
works. You can also call any List method (e.g. add or set). Does this
help?

Equivalent in java would be:
int size = 10;
int[] array= new int[size];
What I want to write in velocity:
// I want to set the length of $array to $size, where $size can be any
number
#set( $size = $JavaHelper.getSize() )
#set( $array = $size )
#foreach( $key in $array )
#end
Right now the above velocity code would not work because $array is not an
array, it is a scalar equal to $size. Thus, the foreach loop would never
be
entered. I would have to write it like this:
//What I have to write in velocity (to make it work):
// I want to set the length of $array to $size, where $size can be any
number (in this case it is 10)
#set( $size = $JavaHelper.getSize() )
//Create $array to size of $size
#set( $array = ["1", "1", "1", "1", "1", "1", "1", "1", "1", "1"...])" )
#foreach( $key in $array )
#end
However the above code is static. I would have to manually enter the array
contents for every possible number. I know you could create a newArray(int
size) method in Java and call that from within the velocity code, but I
was
just wondering if there was a way to do this with purely velocity code.
Thanks for the help! :)
