How to put/get multiple JSONObjects to JSONArray?

Question

Is it possible to store multiple different JSONObjects into a single JSONArray? This is the structure, I want to store in a JSONArray.

[{"value1":1,"value2":900,"value3":1368349},{"value1":2,"value2":1900,"value3":136856},{"value1":3,"value2":600,"value3":136845}] 

Here's the code where I am setting JSONObject and putting it into a JSONArray

if(somecondition) {   // putting values to json object   jsonObj.put("value1", 1);   jsonObj.put("value2", 900);   jsonObj.put("value3", 1368349); } for(int i=0;i<=jsonArray.length();i++){   jsonArray.put(jsonObj);   appObj.setJsonAlarmArray(jsonArray);   // appObj is object of Application Class   editor= sharedPrefs.edit();   editor.putString("key", jsonArray.toString());   System.out.println(jsonArray.toString());   editor.commit(); } 

Using this code only the last value, which I am setting in JSON object Override to all objects. Any suggestions to achieve this?

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray(); try {     for(int i = 0; i < 3; i++) {         // 1st object         JSONObject list1 = new JSONObject();         list1.put("val1",i+1);         list1.put("val2",i+2);         list1.put("val3",i+3);         obj.put(list1);     }  } catch (JSONException e1) {     // TODO Auto-generated catch block     e1.printStackTrace(); }              Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

Once you have put the values into the JSONObject then put the JSONObject into the JSONArray staright after.

Something like this maybe:

jsonObj.put("value1", 1); jsonObj.put("value2", 900); jsonObj.put("value3", 1368349); jsonArray.put(jsonObj); 

Then create new JSONObject, put the other values into it and add it to the JSONArray:

jsonObj.put("value1", 2); jsonObj.put("value2", 1900); jsonObj.put("value3", 136856); jsonArray.put(jsonObj);
