Try this, it will work :
JSONObject jsonObject1 = new JSONObject();
JSONArray jsonArray = new JSONArray();
try {
jsonObject1.put("year", "2019");
jsonObject1.put("amt", "6222");
jsonArray.put(jsonObject1);
JSONObject jsonObject2 = new JSONObject();
jsonObject2.put("year", "2016");
jsonObject2.put("amt", "5555");
jsonArray.put(jsonObject2);
JSONObject jsonObjectList = new JSONObject();
jsonObjectList.put("list",jsonArray);
} catch (JSONException e) {
e.printStackTrace();
}
The result will be:
{"list":[{"year":"2019","amt":"6222"},{"year":"2016","amt":"5555"}]}

@DevanandAdabaile you can use List
to get size of your List (Multiple jsonObject) and set a loop to get size of List – Alireza Haji gholamreza Jun 30 '19 at 08:03

Here is your problem solution, try this
JSONArray jsonArray = new JSONArray();
for (int i =0; i < ItemModelList.size(); i++){
JSONObject jsonObject = new JSONObject();
jsonObject.put("year", String.valueOf(ItemModelList.get(i).getYear()));
jsonObject.put("amt", String.valueOf(ItemModelList.get(i).getAmount()));
jsonArray.put(jsonObject);
requestJson.put("list", jsonArray);
}
Result:
"list": [ { "year": "2019", "amt": 6222 }, { "year": "2016", "amt": 5555 } ]
