Is my whole file being read?

Question

Sorry about the size of this but I think I should supply all the code to help you..
A text file contains 11 lines like this (separated by tabs)
A2 WWP     BMW     535     Exec     12/12/03
The first file calls the GUI file (shown later) and loads the 11 lines of the text file into an array. I think only one line is being loaded but am not sure because on test the output "...No such Vehicle..." from the focusLost method of the second file is displayed. Anyway here is the code and thanks!!
import java.io.*;
import java.util.StringTokenizer;
public class CarDetailsReader{
     static Executive[] cd = new Executive[11];
     static int recordNumber=0;
     static String tabs = "\t";
     static String rN, man, mod, ty, motExp;
     public static void parseLine(String s){
     StringTokenizer st = new StringTokenizer(s, tabs);
     while(st.hasMoreTokens()){
     rN = st.nextToken();
     man = st.nextToken();
     mod = st.nextToken();
     ty = st.nextToken();
     motExp = st.nextToken();
     cd[recordNumber++] = new Executive(rN, man, mod, ty);
public static void LoadArray(){
     FileReader carFile;
     BufferedReader carReader;
     try{
          carFile = new FileReader("cardetails.txt");
          carReader = new BufferedReader(carFile);
          while(carReader.ready()){
               parseLine(carReader.readLine());
          carFile.close();
     catch(FileNotFoundException e){
          System.out.println("File not found");
          System.exit(1);
     catch(IOException e){
          System.out.println("Error reading file");
          System.exit(2);
public static int FindCar(String regNum){
     for(int i=0; i < recordNumber; i++)
          if(cd.GetRegNumber() == regNum) return i;
     return -1;
public static void main(String args[]){
     LoadArray();
     GuiApplication ga = new GuiApplication("Crazy Car Hire LTD Calculator");
     ga.setBounds(100, 100, 500, 300);
     ga.show();
and the second file............

          else

                    CarDetailsReader.cd[recordNumber].GetManufacturer(),

          double c = carType.CalculateSurcharge(Integer.parseInt(txtNoOfDays.getText()));
          lblTHC.setText("Total Hire Cost : " + c);
          show();
Thanks again if you can help

Answer 1

The executive class is as follows:
public class Executive extends Car {
private double surcharge = 1.5;
public double CalculateSurcharge(int noOfDays){
          return (46.5 * noOfDays) * surcharge;
// Stereotype : <<constructor>>
public Executive(String rN, String man, String mod, String ty){
          super(rN, man, mod, ty);
