{

Writer fw = null;

try
{
//fw = new FileWriter( "customer.t xt" );
final FileWriter outputFile = new FileWriter("cus tomer.txt");
final BufferedWriter outputBuffer = new BufferedWriter( outputFile);
final PrintWriter printstream = new PrintWriter(out putBuffer);
fw.write( phoneJTextField + "," + postcodeJTextFi eld );
}
catch ( IOException e ) {
System.err.prin tln( "Cannot write to file" );
}

finally {
if ( fw != null )
try { fw.close(); } catch ( IOException e ) { }
}


}
