LisIterator has add() but doesn't iterate over new added elements

Question

I am using ListIterator to iterate in the list as I want to add few elements during runtime if certain conditions are met.

But the new elements that are added to the list are never included in the iterator

import java.util.ArrayList;
import java.util.List;
import java.util.ListIterator;

public class Example {
    public static void main(String[] s)
    {
        List<Integer> list = new ArrayList<Integer>();
        list.add(1);
        list.add(2);
        list.add(5);
        list.add(6);

        ListIterator<Integer> listIterator = list.listIterator();
        while(listIterator.hasNext())
        {
            int i = listIterator.next();
            System.out.println("List Element: " + i + " | List size: " + list.size());
            if(i==1)
            {
                //Adding '3' to list
                listIterator.add(3);
                System.out.println("Added Element: 3");
            }
            if(i==2)
            {
                //Adding '4' to list
                listIterator.add(4);
                System.out.println("Added Element: 4");
            }
        }
    }
}

Below is the output

List Element: 1 | List size: 4
Added Element: 3
List Element: 2 | List size: 5
Added Element: 4
List Element: 5 | List size: 6
List Element: 6 | List size: 6

I need to make use of the recently added element in current listIterator but not able to do it.

Is there any other way to iterate over the new elements in the same iteration session?

Answer 1

We can use for loop to iterate and add elements to end of the loop at the same time

for (int i = 0; i < list.size(); i++) {
    int element = list.get(i);
    if(element == 1){
        System.out.println(element);
        list.add(3);

    }
    else if(element == 2){
        System.out.println(element);
        list.add(4);
    }
    else
        System.out.println(element);
}
System.out.println(list);

Output:

1
2
5
6
3
4
[1, 2, 5, 6, 3, 4]
