JSONArray and JSONObject Example

Data just look like:


{
       "Id": "10MCA001",
       "Bdate": "30/07/1990",

       "Score": 
       [
           {
               "mid_Exam": 25,
               "outOf": 30
           },
           {
               "gtu_Exam": 231,
               "outOf": 1570
           }
       ],
       "Report": 
       [
           {
               "college_Remarks": "Good",
               "sports_Remarks": "Best",
               "type_of_Sport" : "Cricket"
           }
       ]
   }
