How to add an JsonObject in a JsonArray at some random index - json

Question

I am having a JsonAarray like below:
JsonARray ProfileTabs = [{"totalItemCount":0,"label":"Updates","name":"update"},{"totalItemCount":2,"label":"Members","url":"groups\/member\/list\/129","urlParams":[],"name":"members"},{"totalItemCount":5,"label":"Photos","url":"groups\/photo\/list","urlParams":{"group_id":129},"name":"photos"}]
As in the above JsonArray I am having 3 JsonObject at index 0, 1, 2.
Now I want to add a new JsonObject in this JsonArray at index 1.
So, I have created a new JsonObject as below:
JSONObject InfoTabJsonObject = new JSONObject();
InfoTabJsonObject.put("totalItemCount", 0);
InfoTabJsonObject.put("label", "Info");
InfoTabJsonObject.put("name", "info");
mProfileTabs.put(1, InfoTabJsonObject);
And added this JsonObject to the JsonArray at index 1, but after adding this JsonObject it replaces the original 1st index's JsonObject with the new one.
How can I achieve the index should remain properly, means that new one will be added to 1st index and the other one will adjust their index.
Please help me here, thanks in advanced.

Take a look at the below code, uses org.json.simple.JSONArray and org.json.simple.JSONObject.
JSONObject jsonObj1 = new JSONObject();
jsonObj1.put("totalItemCount", 0);
jsonObj1.put("label", "Updates");
jsonObj1.put("name", "update");
JSONObject jsonObj2 = new JSONObject();
jsonObj2.put("totalItemCount", 2);
jsonObj2.put("label", "Members");
jsonObj2.put("url", "groups/member/list/129");
JSONArray temp = new JSONArray();
jsonObj2.put("urlParams", temp);
jsonObj2.put("name", "members");
JSONObject jsonObj3 = new JSONObject();
jsonObj3.put("totalItemCount", 5);
jsonObj3.put("label", "Photos");
jsonObj3.put("url", "groups/photo/list");
JSONObject temp1 = new JSONObject();
temp1.put("group_id", 129);
jsonObj3.put("urlParams", temp1);
jsonObj3.put("name", "photos");
JSONArray array=new JSONArray();
array.add(jsonObj1); //adding objects into array
array.add(jsonObj2);
array.add(jsonObj3);
try {
// Writing to a file
System.out.println("Before addition of new object into array!");
File file=new File("test1.json");
file.createNewFile();
FileWriter fileWriter = new FileWriter(file);
fileWriter.write(array.toJSONString());
fileWriter.flush();
fileWriter.close();
} catch (IOException e) {
e.printStackTrace();
}
JSONObject InfoTabJsonObject = new JSONObject();
InfoTabJsonObject.put("totalItemCount", 0); //adding objects into array
InfoTabJsonObject.put("label", "Info");
InfoTabJsonObject.put("name", "info");
array.add(1, InfoTabJsonObject);
System.out.println("After addition of new object into array!");
try {
// Writing to a file
File file=new File("test.json");
file.createNewFile();
FileWriter fileWriter = new FileWriter(file);
fileWriter.write(array.toJSONString());
fileWriter.flush();
fileWriter.close();
} catch (IOException e) {
e.printStackTrace();
}
test1.json The orginal one before adding new object in array.
[
{
"name": "update",
"label": "Updates",
"totalItemCount": 0
},
{
"urlParams": [],
"name": "members",
"label": "Members",
"url": "groups\/member\/list\/129",
"totalItemCount": 2
},
{
"urlParams": {
"group_id": 129
},
"name": "photos",
"label": "Photos",
"url": "groups\/photo\/list",
"totalItemCount": 5
}
]
test.json The updated one after adding new object in array.
[
{
"name": "update",
"label": "Updates",
"totalItemCount": 0
},
{
"name": "info",
"label": "Info",
"totalItemCount": 0
},
{
"urlParams": [],
"name": "members",
"label": "Members",
"url": "groups\/member\/list\/129",
"totalItemCount": 2
},
{
"urlParams": {
"group_id": 129
},
"name": "photos",
"label": "Photos",
"url": "groups\/photo\/list",
"totalItemCount": 5
}
]
