Program:

            /* ............... START ............... */
                
import java.util.ListIterator;
import java.util.ArrayList;

public class JavaRemoveElementListIterator {

	public static void main(String[] args) {

		// create an object of ArrayList
		ArrayList arrayList = new ArrayList();

		// Add elements to ArrayList object
		arrayList.add("1");
		arrayList.add("2");
		arrayList.add("3");
		arrayList.add("4");
		arrayList.add("5");

		ListIterator listIterator = arrayList.listIterator();

		listIterator.next();
		listIterator.next();

		// remove element returned by last next method
		listIterator.remove();

		System.out.println("After removing 2, ArrayList contains");
		for (int intIndex = 0; intIndex < arrayList.size(); intIndex++)
			System.out.println(arrayList.get(intIndex));

	}
}
                /* ............... END ............... */
        

Output

After removing 2, ArrayList contains
