Using ObjectOutputStream with a FileOutputStream is relatively easy but it won't produce a "text" file. If your desire is to produce a file that is human readable you'll need to go another route.
by using ObjectOutputStream with a FileOutputStream u will have to read UTF or byte(for String) and write UTF or byte (forString)..
try using
PrintWriter abc=new PrintWriter(new FileWriter(Filename));
/// and to write into filename use
abc.println(String or may be product1.addNewProduct);
