LinkedList example in java

This program does the same thing as above using java.util.LinkedList, which hides the linking infrastructure and extra class. It is a doubly-linked list so moving in both directions is possible.

package linkedlistexamples;
import java.util.*;
public class LibraryLinkedList {
    public static void main(String[] args) {
         Scanner in = new Scanner(System.in);
         LinkedList lst = new LinkedList();
           //... Read and build list of words.
         while (in.hasNext()) {
            String word = in.next();
            lst.add(word);
        }
            //... Enhanced for loop to print list forward.
        //    Could also use an Iterator (forward only) or
        //    ListIterator (forward or backward).
        System.out.println("*** Print words in order of entry");
        for (String s : lst) {
            System.out.println(s);
        }
                //... Use ListIterator go to backward.  Start at end. 
        System.out.println("*** Print words in reverse order of entry");
        for (ListIterator lit = lst.listIterator(lst.size());
                            lit.hasPrevious();) {
            System.out.println(lit.previous());
        }
    }
}
