How to ensure File Read Adapter handles like SQLLOADER's TRAILING NULLCOLS

Question

I have to read a CSV file which has a specific format but sometimes the trailing columns values can be missing and i would like to handle it in such way that they values are treated as null. This is similar to the SQLLoader's TRAILING NULLCOLS clause.
Currently if my data is as shown below:
As-Of Date,As-Of-Time,Bank ID,Bank Name,State,Acct No,Acct Type,Acct Name,Currency,BAI Type Code,Tran Desc,Debit Amt,Credit Amt,0 Day Flt Amt,1 Day Flt Amt,2+ Day Flt Amt,Customer Ref No,Value Date,Location,Bank Reference,Tran Status,Descriptive Text,Descriptive Text1,Descriptive Text2,Descriptive Text3,Descriptive Text4,Descriptive Text5,Descriptive Text6

It reads the first row properly , but when in encounters the second row POSTED column , it tries to find the terminated column and since it is not present it reads data from the next line until it finds a comma.
This is not the way i would like to handle it.
We get around 1000-2000 records in that CSV from the Bank and they cant change the way they are sending the file. So , please help in resolving this issue.
Thanks

Hi thanks for the reply
well i've been having a play around but haven't got it to work yet,
Here's what i have so far
private void jButton2MouseClicked(java.awt.event.MouseEvent evt) {
         BufferedReader  sb = new BufferedReader();
       sb.append(""+jTextField1.setText()+",");
       sb.append(""+jFormattedTextField1.setText()+"\n");
       sb.append(""+jTextField2.setText()+",");
       sb.append(""+jFormattedTextField2.setText()+"\n");
       sb.append(""+jTextField3.setText()+",");
       sb.append(""+jFormattedTextField3.setText()+"\n");
       sb.append(""+jTextField4.setText()+",");
       sb.append(""+jFormattedTextField4.setText()+"\n");
       sb.append(""+jTextField5.setText()+",");
       sb.append(""+jFormattedTextField5.setText()+"\n");
       ReadFromFile(sb.toString());
    private void ReadFromFile(String s) {
        try {
        BufferedReader in = new BufferedReader(new FileReader("/users/data.txt"));
        String str;
        while ((str = in.readLine()) != null) {
            Process(str);
        in.close();
    } catch (IOException e) {
    }// TODO add your handling code here:
                }im thinking the problem is the parts that say sb.append but i don't know what to in it's place?
