Create JSON Array and JSON Object

Students

• 0
  • id : "1"
  • name : "abc"
• 1
• id : "2"
• name : "xyz"

private String writeJSON() {

             JSONObject student1Detail = new JSONObject();

             try {

                    student1Detail.put("id", "1");

                    student1Detail.put("name", "abc");

             } catch (JSONException e) {

                    e.printStackTrace();

             }

             JSONObject student2Detail = new JSONObject();

             try {

                    student2Detail.put("id", "2");

                    student2Detail.put("name", "xyz");

             } catch (JSONException e) {

                    e.printStackTrace();

             }

             JSONArray jsonArray = new JSONArray();

             jsonArray.put(student1Detail);

             jsonArray.put(student2Detail);

             JSONObject studentsObj = new JSONObject();

             try {

                    studentsObj.put("Students", jsonArray);

             } catch (JSONException e) {

                    e.printStackTrace();

             }

             String jsonStr = studentsObj.toString();

             System.out.println("jsonString: " + jsonStr);

             return jsonStr;

       }

Output :

{"Students":[{"id":"1","name":"abc"},{"id":"2","name":"xyz"}]}
