For this question, we use the list iterator of Java. This iterator has a method add. Hence, the iterator can add elements to a list.

import java.util.ListIterator; import java.util.LinkedList; public class Test { public static void main( String[] args ) { LinkedList a, b; a = new LinkedList(); b = new LinkedList(); a.add("alpha"); a.add("bravo"); a.add("tango"); a.add("charlie"); ListIterator i, j; i = a.listIterator(); j = b.listIterator(); while (i.hasNext()) { j.add(i.next()); } System.out.println(a); System.out.println(b); } }

What is the result of the execution of the above Java program?

1.charlie, tango, bravo, alpha charlie, tango, bravo, alpha

2.alpha, bravo, tango, charlie alpha, bravo, tango, charlie

3.charlie, tango, bravo, alpha alpha, bravo, tango, charlie

4.alpha, bravo, tango, charlie charlie, tango, bravo, alpha

5.Runs into an infinite loop
