Thread: What's wrong with my code ?

What's wrong with my code, it is not giving output properly.

import java.util.*;
 
public class Llist {
 
        public static void main(String[] args) {
 
                String[] things = {"Apple", "Banana", "Orange", "Mango", "Grapes"};
 
                List<String> list1 = new LinkedList<String>();
                for(String x : things)
                        list1.add(x);
 
                String[] things2 = {"Briyani", "Chicken", "Meat", "Fish"};
 
                List<String> list2 = new LinkedList<String>();
                for(String y : things2)
                        list2.add(y);
 
                list1.addAll(list2);
                list2 = null;
 
                printMe(list1);
                removeStuff(list1, 2, 3);
                reverseMe(list1);
 
        }
 
        private static void printMe(List<String> l) {
                for(String b : l)
                        System.out.printf("%s ", b);
                System.out.println();
        }
 
        private static void removeStuff(List<String> l, int from, int to) {
                l.subList(from, to).clear();
        }
 
        private static void reverseMe(List<String> l) {
                ListIterator<String> bobby = l.listIterator(l.size());
                while(bobby.hasPrevious())
                        System.out.printf("%s ", bobby.hasPrevious());
        }
}

What should the proper output be?
