public void writeCd() throws Exception
String outputFileName;
PrintWriter outputFile;
outputFileName = "D:\\cdoutput.txt";
outputFile = new PrintWriter(new FileWriter(outputFileName,true));
int loopTest;
do
String numStr = JOptionPane.showInputDialog("Please enter Index number");
int number = Integer.parseInt(numStr);
cC.setIndexNumber(number);
numStr = JOptionPane.showInputDialog("Please enter cd name");
number = Integer.parseInt(numStr);
cC.setCdName(number);
String message = cC.toString() +
"\nYour input is: ";
JOptionPane.showMessageDialog(null, message);
outputFile.println(numStr + "");

class findCD implements ActionListener
       public void actionPerformed(ActionEvent event)
            try
                 writeCd();
            } catch(Exception e){
                                    e.printStackTrace();
  public void writeCd() throws Exception
      String outputFileName;
      PrintWriter outputFile;
      outputFileName = "D:\\cdoutput.txt";
outputFile = new PrintWriter(new
(new FileWriter(outputFileName,true));
         int loopTest;
         do
String numStr =
umStr = JOptionPane.showInputDialog("Please enter
Index number");
         int number = Integer.parseInt(numStr);
         cC.setIndexNumber(number);
numStr = JOptionPane.showInputDialog("Please
"Please enter cd name");
         number = Integer.parseInt(numStr);
         cC.setCdName(number);
         String message = cC.toString() +
                          "\nYour input is: ";
         JOptionPane.showMessageDialog(null, message);
        outputFile.println(numStr + "");
loopTest =
pTest = JOptionPane.showConfirmDialog(null,"Do
another?","",0,1);
         while (loopTest == 0);
       outputFile.close();
    }That should work. This also assumes that the method writeCd is in the class findCD.
