Common Operations on ArrayList Using Iterator
You can safely remove elements while iterating:
while (iterator.hasNext()) {
String name = iterator.next();
if (name.equals("Alice")) {
iterator.remove();
}
}Example of Modifying Elements
Modifying elements is generally done with a ListIterator:
ListIterator<String> listIterator = names.listIterator();
while (listIterator.hasNext()) {
String name = listIterator.next();
if (name.equals("Bob")) {
listIterator.set("Robert");
}
}
