org.json.JSONException: A JSONArray text must start with '[' at 1 [character 2 line 1] - how to solve?

JsonArray Is:

{
  "list": [
    {
      "name": abc,
      "start_date": "2017-5-18 0:30:00",
      "end_date": "2017-6-1 0:30:00",
      "start_address": "Gujarat 380060, India",
      "end_address": "Ognaj, Ahmedabad, Gujarat, India"
    },
    {
      "name": pqr,
      "start_date": "2017-5-18 0:30:00",
      "end_date": "2017-6-1 0:30:00",
      "start_address": "Gujarat 380060, India",
      "end_address": "Ognaj, Ahmedabad, Gujarat, India"
    }
  ]
}

java code using springBoot is bellow

@RequestMapping(value = "/addabc", method = RequestMethod.POST)

@CrossOrigin
public Map addabc(@RequestBody String data, HttpServletRequest request) {

JSONArray jsonArray=new JSONArray(data);

try{

for(int i=0; i < jsonArray.length(); i++) {
  JSONObject jsonobject = jsonArray.getJSONObject(i); 
   ......
   ......

}

}catch (Exception e) { ... }

Getting exception is:-

First, the JSON you given is not an array. Only the "list" object is an array.

Second, the value of "name" should be in "" (like "name": "pqr",) in both object in "list". So provided json is not valid.

For valid json following code is giving you the JSONObject from JSONArray

        JSONParser parser = new JSONParser();
        JSONObject json = (JSONObject) parser.parse(data);

        JSONArray jsonArray = (JSONArray) json.get("list");
        for (int i = 0; i < jsonArray.size(); i++) {
            JSONObject jsonobject = (JSONObject) jsonArray.get(i);
            .....
            .....
        }
