Removing elements from array list with the iterator

Remove elements from array list using iterator object :

Code:

import java.util.ArrayList;
import java.util.Iterator;

public class ArraysWork {

    public static void main(String[] args) {


        ArrayList charsList = new ArrayList();
        for (char alphabet = 'A'; alphabet < 'H'; alphabet++) {
            charsList.add(alphabet);
        }
        Iterator iterator1 = charsList.iterator();
        while (iterator1.hasNext()) {
            System.out.print(iterator1.next() + " \n");
            iterator1.remove();
        }
        Iterator iterator2 = charsList.iterator();
        while (iterator2.hasNext()) {
            System.out.print("The array is not empty");

        }

    }
}
 

The output is :

Code:
