Need iterator loop help.

So i'm making a plugin and I need the code to dispatch a command while a 2 string lists.hasNext(). the two lists have different numbers of names inside of them so the while code won't run when one of the lists runs out of names. And I dont want it to stop if string list #1 or list #2 is out of names but only if both of them are out of names. Does anyone know how i would go about doing this?

 

Here's the code that regards this:

Code (Text):

          if (args[1].equalsIgnoreCase("confirm"))
          {
              Iterator<String> it = allsubmits.iterator();
              Iterator<String> i = world.iterator();
              while(Stuff i need help on)
              {
                  String submitting = it.next();
                  String worldz = i.next();
                  Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(),"lp user " + submitting + " permission unset worldguard.build.* global " + worldz);
              }

 

i've tried that but. lets say "it" only has 1 name in it and "i" has 2. The command won't dispatch after it's read "it" because it only has 1 and it just read that one and now the && statement is now false because "it" doesn't have next.
