Json array manipulation in android

Question

If I have a Json array object that looks like this:

[
    {"values here"},
    {"values here"},
    {"values here"}
]

And I want a Json array object that looks like this:

    {
        "key1":"value1","key2":"value2","key3":"value3"
         :[
             {"values here"},
             {"values here"},
             {"values here"}
          ]
    }

Is it possible for me to insert another json object at the front of all the elements in the array and encloses them.

I'm not sure what you mean by "encloses".

You can have the first element of the array be your object.

[
   {
     "key1": "value1",
     "key2": "value2",
     "key3": "value3"
   },
   "values here",
   "values here",
   "values here"
]

You can also have an object like

{
   "first": {
     "key1": "value1",
     "key2": "value2",
     "key3": "value3"
   },
   "rest": [
     "values here",
     "values here",
     "values here"
   ]
}

I would like the object : "key1":"value1","key2":"value2","key3":"value3" to be the first element, then everything else inside that. – Mar 31 '14 at 13:47
If it's "inside" the object, then the object needs to have a `"key4"` containing the array with the rest of the values. If the object only has three keys, you cannot have any other values inside it. – Vlad Mar 31 '14 at 13:49

Use the following Example

JSONObject student1 = new JSONObject();
try {
  student1.put("id", "3");
  student1.put("name", "NAME OF STUDENT");
  student1.put("year", "3rd");
  student1.put("curriculum", "Arts");
  student1.put("birthday", "5/5/1993");

} catch (JSONException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}

JSONObject student2 = new JSONObject();
try {
  student2.put("id", "2");
  student2.put("name", "NAME OF STUDENT2");
  student2.put("year", "4rd");
  student2.put("curriculum", "scicence");
  student2.put("birthday", "5/5/1993");

} catch (JSONException e) {
// TODO Auto-generated catch block
  e.printStackTrace();
}


JSONArray jsonArray = new JSONArray();

jsonArray.put(student1);
jsonArray.put(student2);

JSONObject studentsObj = new JSONObject();
studentsObj.put("Students", jsonArray);



String jsonStr = studentsObj.toString();

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