I am using OKHttp to send multipart data. Here a piece is my code:

 MultipartBody.Builder bodyBuilder = new MultipartBody.Builder();
bodyBuilder.setType(MultipartBody.FORM)
 .addFormDataPart("arrival_to", object.optString("arrival_to"))
 .addFormDataPart("centre_id", object.optString("centre_id"))
 .addFormDataPart("departure_from", object.optString("departure_from"))
 .addFormDataPart("expense_item_id", object.optString("expense_item_id"))
 .addFormDataPart("expense_sub_item_id", object.getString("expense_sub_item_id"))
 .addFormDataPart("file_list", object.optString("file_list"))
 .addFormDataPart("journey_date", object.optString("journey_date"))
 .addFormDataPart("passenger_age", object.optString("passenger_age"))
 .addFormDataPart("passenger_gender", object.optString("passenger_gender"))
 .addFormDataPart("passenger_name", object.optString("passenger_name"))
 .addFormDataPart("personal_id", object.optString("personal_id"))
 .addFormDataPart("remarks", object.optString("remarks"))
 .addFormDataPart("request_amount", object.optString("request_amount"))
 .addFormDataPart("request_status", object.optString("request_status"))
 .addFormDataPart("travel_class", object.optString("travel_class"))
 .addFormDataPart("vehicle_name_no", object.optString("vehicle_name_no"))
 .addFormDataPart("vendor_id", object.optString("vendor_id"))
 .addFormDataPart("vendor_type_id", object.optString("vendor_type_id"))
 .addFormDataPart("within_budget", object.optString("within_budget"))
 .addFormDataPart("file_list", attach_file, RequestBody.create(MediaType.parse(type), file))
 .build();

The problem here is that I am adding the form data parts one by one which is ok here but I wanted to use a loop to add the form data part in case the dataset increased. Also I am making a seperate class containing the code to upload the data, how do I pass the key value pairs to that class should I use a Map?

Maybe something like this works?

MultipartBody.Builder bodyBuilder = new MultipartBody.Builder();
MultipartBody.Builder builder = bodyBuilder.setType(MultipartBody.FORM);

String keys = new String
 "arrival_to",
 "centre_id",
 "departure_from",
 "expense_item_id",
 "...."

;

Arrays.stream(keys)
 .forEach(key -> 
 builder.addFormDataPart(key, object.optString(key));
 );

}
