Create an array of JSON Objects

Question

I need to create a JSON Object for an Arraylist. Below is the code

public boolean submitOrder(ArrayList orderList) {

        serUri          


        

Answer 1

Your JSONObject json = new JSONObject(); should be within the loop.

Additionally, you should not do a get(i) each time to access properties (for performance). You can use the other construct of the for loop:

for (OrderDetailsData data : orderList) {
  JSONObject json = new JSONObject();
  json.put("orderno", data.getOrderNumber().toString());
  // ...
}

Finally, maybe you should consider having a function that reads/writes a JSON object from an OrderDetailsData so that you can reuse the code in other webservices.
