I have two ArrayLists: List<Boolean> A and List<T> B with same size. I

iterators. Can I use foreach in java for that? Any decent approach
instead of nested loops?
Ok so what I understand you want is an iterator that will set all
boolean values in list B to be the same as list A. I am assuming the
type of list B (T) is actually Boolean, if not you can change the
setter. As far as the iterator, you were close.
Here is a simple example:
for(int i; i<A.size(); i++)
{
B.set(i, A.get(i));
}
This assumes the List B is already has elements which you're replacing
with the elements in A. If List B is empty you could just use the add
method instead:
for(int i; i<A.size(); i++)
{
B.add(A.get(i));
}
