Splitting an ArryList to produce two other ArrayLists

Question

Hello, I am still strying to figure this out. Thanks for the replies to the previous post. So I have an ArrayList now:
ll = [New Mexcio/Albuquerque
, California/Los Angeles, Illinois/Chicago, New York/New York, Arizona/Phoenix, Oregon/Portland] It consists of 6 entries and the goal is to make two separate ArrayLists holding states and cities separately. My idea was to iterate through the first ArrayList and do another split for each entry, putting the two tokens into two different ArrayLists each time.. I was trying to do all that in one for each loop only, but I dont think there is a way. I am copying the code, which throws a runtime exception:java.util.NoSuchElementException... Any ideas welcome..
import java.util.*;
import java.io.*;
public class ScannerFile {
    public static void main(String[] args) throws Exception {
        Scanner sc = new Scanner(new File("statecity.txt"));
        sc.useDelimiter("\n");
        List<String> ll = new ArrayList<String>();
        List<String> st = new ArrayList<String>(); //hold states only
        List<String> ct = new ArrayList<String>(); //hold cities only
      while (sc.hasNext()) {
        ll.add(sc.next());  
        System.out.println(ll); //just printing
        System.out.println("    " +ll.size());//just printing
      for(String s:ll){
          Scanner ss = new Scanner(s); //Second Scanner to
           ss.useDelimiter("/");
            while (ss.hasNext()) {
            st.add(sc.next());  
          System.out.println(s); //Just printing the entries..Is further split possible in here?
}

Deco,
Here's a wee hint... why 2 lists?
Wouldn't a Place class be simpler, and more flexible?class Place {
   public String city;
   public String state;
   Place(String citySlashState) {
      String[] s = citySlashState.split("/");
      this.city = s[0];
      this.state = s[1];
List<Place> places = new ArrayList<Place>;... just a suggestion...
