This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I'm not entirely sure what you're trying to do. Are you trying to iterate over multiple lists at the same time? I'm pretty sure you can't do that (but could be wrong). It'd be better to build a more reasonable data structure before you get to the template.
No, it's not possible to loop through multiple lists like that. But, if these lists are arrays or implement the List interface, and have the same size, you can use the index of the loop : (I think, needs to be checked...)
But as David said, a better data structure should avoid that crap
