Question

I need below kind of structure constructed in java and send it as response :

var abc = {
  "action": "         


        

Answer 1

JSONObject json = new JSONObject();
json.put("fromZIPCode","123456"); 

JSONObject json1 = new JSONObject();
json1.put("fromZIPCode","123456"); 
       sList.add(json1);
       sList.add(json);

System.out.println(sList);

Output will be

[{"fromZIPCode":"123456"},{"fromZIPCode":"123456"}]
