out.println("<table>");
out.println("<tr>");
out.println("<td>"+id+"</td>");

tong +=price[temp];

discount=((tong*5)/100);
out.println("You yet discount <font color=red>5% </font>total number money:<br>");
out.println("Money Discount: <font color=red>"+discount+"</font><br>");
out.println("Total Pay: <font color=red>"+(tong - discount)+"</font>");
}
out.println("<br><br>");
RequestDispatcher dispatche=getServletContext().getRequestDispatcher("/include.html");
dispatche.include(request,response);
out.close();
}

và cuối cùng tạo 1 trang để điền thông tin khách hàng và include nó ở cuối Product.java
