如何使用Iterator从java中的主列表中删除整个列表

Question

I have one List<List<Address>> object and another List<AddressList> Object. I have to iterate through this list and keep deleting objects from list after my first loop executes. How can I do this?

List<List<Address>> addressLists;
List<Address> addressList;
for (List<Address> listOfAddress : this.addressLists) {
    for (Address address : listOfAddress) {
        //some code
    }
}

How can I delete or remove object from addressLists after processing?

PS I am using Java 7.

Use an explicit iterator:

Iterator<List<Address>> iter = this.addressLists.iterator();
while (iter.hasNext()) {
    List<Address> listOfAddress = iter.next();
    for (Address address : listOfAddress) {
        //some code
    }
    iter.remove();
}
