I have problem using the BufferWriter

Question

I have problem using the BufferWriter. I try to write the data to a *.txt file. However, I do not know how to add the data in but not over write the previous data. Can anyone help me please?
Also the productID cannot be written into the *.txt file, the type of productID is int. Don't know why this happen...
public void writeInfo()
    try{
    PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("C:\\Documents and Settings\\Charles\\My Documents\\testing.txt")));
    out.write("\n");
    out.write(productID);
    out.write("  ");
    out.write(productName);
    out.write("  ");
    out.write(originalCountry);
    out.write("  ");
    out.write(Double.toString(price));
    out.write("  ");
    out.write(productCategory);
    out.write("  ");
    out.write(Double.toString(vatPrice));
    out.write("  ");
    out.write(manufacturerName);
    out.write("  ");
    out.write(manufacturerAddress);
    out.write("  ");
    out.write(warranty);
    out.flush();
    out.close();
    catch(IOException ex)
     ex.printStackTrace();
  }
