In Java, how to traverse two lists at the same time?

Question

E.g.

for(String str : list1) {
...
}

for(String str : list2) {
...
}

suppose we are sure that list1.size() equals list2

Answer 1

In case someone is interested, this is the solution that will iterate fully thru both lists even if they are not of the same size.

int max = Math.max(list1.size(), list2.size());
for(int i=0; i<max; ++i){
    if(list1.size()<i){
        list1.get(i);
    }
    if(list2.size()<i){
        list2.get(i);
    }
}
