                                   ob.put("ServiceVisitID","1");
                                    ob.put("ServiceItemID","1");
                                    ob.put("ItemDescription","check");
                                    ob.put("SerialNumber","check");
                                    JSONObject itemlocationob=  ob.put("SerialNumber");
                                   ob.put("ItemLocation","check");

                                    JSONArray ServiceTasks=new JSONArray();
                                    JSONObject ServiceTasksob=new JSONObject();

                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasks.put(jsonObject1);
                                    ob.put("",ServiceTasks);

What exactly is your question? What have you tried? Furthermore, that is not valid JSON. — Ken Y-N, Jun 15 '17 at 08:34

JSONObject jObj = new JSONObject();
jObj.put(KEY,VALUE);
JSONArray jArray = new JsonArray();
jArray.put(jObj);
JSONObject mainJson = new JSONObject();
mainJson.put(KEY,mainJson);

While this code may answer the question, providing additional context regarding how and/or why it solves the problem would improve the answer's long-term value. – Badacadabra Jun 15 '17 at 15:01

    In an JSONObject we can follow as key value pairs
Considering your code,
JSONArray jsonArray=new JSONArray();
                                    JSONObject ob=new JSONObject();

                                   ob.put("ServiceVisitID","1");
                                    ob.put("ServiceItemID","1");
                                    ob.put("ItemDescription","check");
                                    ob.put("SerialNumber","check");
                                    **//  Wrong version
                                    JSONObject itemlocationob=  ob.put("SerialNumber");  
                                    ob.put("ItemLocation","check");**
                                    //
                                    **//Right version
                                    JSONObject itemlocationob=  new JSONObject();
                                    itemlocationob.put("SerialNumber","<some value>");
                                   ob.put("ItemLocation",itemlocationob);

                                    JSONArray ServiceTasks=new JSONArray();
                                    JSONObject ServiceTasksob=new JSONObject();

                                    ServiceTasks.put("TaskID","1");
                                    ServiceTasks.put("TaskID","2");
                                    ServiceTasks.put("TaskID","3");
                                                                                          ServiceTasksob.put("ServiceTasks",ServiceTasks);
                                    ob.put("service",ServiceTasksob);
                                   //**

I guess this kind of json you are trying to build. Hope that helps!!!
