Help with Sorting with Comparator

Can someone plz help me debug. idk why im getting NumberFormatException here. im trying to sort the data by CODE first then by Time. Here is my code. thanks in advance

[CODE]
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;

import java.text.SimpleDateFormat;
import java.util.Collections;
import java.util.Comparator;
import java.util.Date;
import java.util.Vector;

public class Codesort {

public Codesort() {
super();

}

/**

* @throws ParseException
*/
public static void main(String[] args) throws ParseException {
// TODO Auto-generated method stub

try {
BufferedReader br = new BufferedReader(new FileReader(new File("Location of file")));
String logLine = "";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
// SimpleDateFormat sdfDate = new SimpleDateFormat("d-MMM");
// SimpleDateFormat sdfTime = new SimpleDateFormat("H:mm");
sdf.setLenient(false);
DecimalFormat df = new DecimalFormat("0000");
Vector v = new Vector();

while((logLine = br.readLine())!=null){
String fields[] = logLine.split(",");
for (int i = 0; i < fields.length; i += 1) {
//this just strips the quotes
while (fields[i].startsWith("\"")) {
fields[i] = fields[i].substring(1);
}
while (fields[i].endsWith("\"")) {
fields[i] = fields[i].substring(0, fields[i].length() - 1);
}
String tempDate = fields[0].substring(fields[0].indexOf(":")+1);
tempDate = tempDate.substring(tempDate.indexOf("\"")+1);
//Date temp = sdf.parse(tempDate);
//String date = sdfDate.format(temp);
//String time = (sdfTime.format(temp));

{
//ts is the time
String ts = fields[0].substring(fields[0].indexOf(":")+1);
//field that has the codes
int tempCode = Integer.parseInt(fields[13] + fields[14]);
String code = df.format(tempCode);
Summary s = new Summary();
s.setTime(ts);
s.setCODE(code);
v.add(s);

Collections.sort(v, new Sort());

System.out.println(v);

} }}}
