Question

I know I can do a loop, but then how I get it to traverse 2 of them at same time??? Also, I have no idea the size of the list, so I cant use a for loop. Rather, a while loop is prob need to be used… Is it going to be a big boolean expression?

I will try what I can, thank for some ideas.

This is how it’s done with two iterators:

for (Iterator<String> it1 = list1.iterator(), it2 = list2.iterator(); 
     it1.hasNext() && it2.hasNext();) 
{
   final String s1 = it1.next(), s2 = it2.next();
   // stuff to do
}
