C#/Java/Velocity get contents of array

I am programming with Velocity, but the logic is very near to C# and Java. So I got an two-dimensional array:

[0, 13], [1,1], [2,5] and so on.

Now i want to use these numbers like the following. How?

{
    "country": 0,
    "litres": 13
  },    
{
    "country": 1,
    "litres": 1
  },
{
    "country": 2,
    "litres": 5
  },

For example With the follow code I get 0 13 1 1 2 5

    #set($start = 0)
    #set($end = $list.size - 1)
    #set($range = [$start..$end])
    #foreach($i in $range)
       #foreach($j in $range)
         $list.get($i).get($j)
       #end
    #end

In Velocity I only can use foreach loops.

Thanks in advance!

Do you have an array (one-dimensionnal) containing couples or a two-dimensional array? In the first case I would do something like

foreach($i in $range)
    country = $list.get($i).getFirst()
    litres = $list.get($i).getSecond()
