Search Through File with OPENCSV

Question

All,
I am searching thru a .csv file for using regular expressions. I am looking for a patter that looks like a date: mm/dd/yyyy.
I search for the pattern while reading my .csv file. Since I am in a loop, I can't get a permanent handle on the search result. How can I get a permanent handle on it?
When I come out the loop, the date is empty or null.
How can I get the one occurrence, and save it?
Code:
package mybeans;
import org.apache.regexp.*;
import java.util.LinkedList;
import ClientDataProc.Logging;
import ClientDataProc.BalancesDataClass;
import ClientDataProc.ControlsAccess;
import au.com.bytecode.opencsv.CSVReader;
import java.util.List;
import java.io.*;
import java.io.FileReader;
import java.io.IOException;
public class CSVBalances {
static String find="";
//lets get headers from config file.
String[] headers;
String finalDate ="";
static String date ="";
private static Logging log = new Logging();
public static void main(String[] args) throws IOException {
          CSVBalances test = new CSVBalances();
          test.readData("Cash.csv", "royal.csv");
          System.out.println("From main" +date);
     public LinkedList<BalancesDataClass> readData(String filename, String config)throws IOException {
          ControlsAccess controls = new ControlsAccess(log);
          BalancesDataClass balances = new BalancesDataClass(controls, filename, -1,log);
          LinkedList<BalancesDataClass> list = new LinkedList<BalancesDataClass>();
          //lets get the date out of the file.
          CSVReader readerDate = new CSVReader(new FileReader(filename));
          String [] nextLineDate;
          while((nextLineDate = readerDate.readNext()) != null){
               for(int i = 0;i<nextLineDate.length;i++){
               finalDate = findDate(nextLineDate);
               if(finalDate != null || finalDate != ""){
                    date = finalDate;
                    System.out.println(date);
                    break;
               break;
               //now we read the data file.
               CSVReader reader = new CSVReader(new FileReader(filename),',','\"',3);
               String [] nextLine;
               //read the configuration file.
               File configFile = new File(config);
               CSVReader configReader = new CSVReader(new FileReader(configFile));
               while((headers = configReader.readNext()) != null){
                    //lets find the date in the file:
                    while ((nextLine = reader.readNext()) != null) {
                    for(int h =0; h<headers.length;h++){
                         System.out.println(headers[h] + nextLine[h]);
                         //add to our objects BalancesDataClass/ClientDataClass.
                         balances.saveData(headers[h], nextLine[h]);
               }return list;
     private static String findDate(String part){
          String date="";
          String pattern = "[0-9][0-9]" + "/" + "[0-9][0-9]" + "/" + "[0-9][0-9]";
          RE r = new RE(pattern);
          if(r.match(part)){
               //System.out.println("The match is: " + r.getParen(0));
               date = r.getParen(0);
          return date;
public String getDate(){
     return this.date;

Here is the snippet of my code. Can someone please take a look at it.
while ( (dbRecord = dis.readLine()) != null) {
StringTokenizer st = new StringTokenizer(dbRecord, ":", false);
Vector row = new Vector();
String lineTemp;
while (st.hasMoreTokens()) {
if (st.nextToken().trim().equalsIgnoreCase(userinput)) {
//System.out.println(dbRecord);
StringTokenizer tempst = new StringTokenizer(dbRecord, ":", false);
while (tempst.hasMoreTokens()){
row.addElement(tempst.nextToken());
dataVector.addElement(row);
}
