Storing file contents in a Collection

Question

Hi All,
Im trying to read a csv file, break the lines by comma, then store them and sort them.
I have the test code working from: http://java.sun.com/docs/books/tutorial/collections/interfaces/order.html
I am reading the file, but when I System.out.println() I keep getting the last line of the file only. Why is that?
     try {
          BufferedReader in = new BufferedReader(new FileReader("/Users/custodian/Desktop/list.csv"));
String line;
//Start reading the file while
while ((line = in.readLine()) != null) {
// System.out.println(line);
StringTokenizer st = new StringTokenizer(line, ",");
//Counting tokens while
while (st.hasMoreTokens()){
     count++;
     //System.out.println(st.nextToken());
     fullname = st.nextToken();
     StringTokenizer wsp = new StringTokenizer(fullname, " ");
     //breaking full name apart while
     while(wsp.hasMoreTokens()){
          fname = wsp.nextToken();
          lname = wsp.nextToken();
     email = st.nextToken();
     phone = st.nextToken();
     streetaddress = st.nextToken();
     city = st.nextToken();
     state = st.nextToken();
     zip = st.nextToken();
     contactArray = new Contact(fname, lname, email, phone, streetaddress, city, state, zip);
     System.out.println(contactArray.toString());
     List <Contact> contacts = Arrays.asList(contactArray);
     Collections.sort(contacts);
     System.out.println(contacts);

Hi,
im trying to sort by state then write to another file:
I keep getting an error on Collections.sort(contacts, new StateComparator());
Collections.sort(contacts, new StateComparator());
                         try {
                              BufferedWriter out = new BufferedWriter(new FileWriter("state-sort.csv"));
                              //PrintWriter p = new PrintWriter(out);
                              out.write(firstLine + "\n");
                              Iterator it = contacts.listIterator();
                              while(it.hasNext()) {
                              Object o = it.next();     
                              out.write(o.toString() + "\n");
                              out.flush();
                              out.close();
                         }catch(FileNotFoundException ee) {}
                         catch(IOException ioe) {}
Here is my Comparator
package mybeans;
class StateComparator implements Comparable
     String state;
     public String getState() { return state; }
     public int compare(Object obj1, Object obj2)
          if(obj1 == obj2)
               return 0;
          Contact c1 = (Contact) obj1;
          Contact c2 = (Contact) obj2;
          return c1.getState().compareTo(c2.getState());
     public int compareTo(Object obj)
          Contact c = (Contact) obj;
          return (state).compareTo(c.state + c.state);
Any help appreciated.
