How to add element in List while iterating in java?

Question

Say I have a List like:

List list = new ArrayList<>();
list.add(\"a\");
list.add(\"h\");
list.add(\"f\");
list.add(\"s\");

Answer 1

Just iterate the old-fashion way, because you need explicit index handling:

List myList = ...
...
int length = myList.size();
for(int i = 0; i < length; i++) {
   String s = myList.get(i);
   // add items here, if you want to
}
