String is not supported by the format method. It needs to be an instance of Number. See stackoverflow.com/questions/45274167/…

There is a couple of issues here.
- As mentioned in the comments, you cannot provide the
DecimalFormat.formatmethod with aStringvalue. It needs to be a subtype ofNumber. This can be solved by parsing the response ofmf.getParameter("pprice"))to a double. Like this:
decimalformat.format(Double.parseDouble(mf.getParameter("pprice")));
- There is really no point in doing this at all when you are converting it back to a Double afterwards. You might as well just do
product.setPrice(Double.parseDouble(mf.getParameter("pprice")));. The formatting is lost anyways.
