Convert JsonObject to String

{
    "data": 
    {
        "map":
        {
            "allowNestedValues": true,
            "create": "2012-12-11 15:16:13",
            "title": "test201212110004",
            "transitions": []
        }
    },
    "msg": "success",
    "code": "0"
}

Above is a JsonObject, the data is a JsonObject.

How to convert it to a String like "msg":"success" as you know, i can't directly add a double quotes outside data's value.

Solution 1:

There is an inbuilt method to convert a JSONObject to a String. Why don't you use that:

JSONObject json = new JSONObject();

json.toString();

Solution 2:

You can use:

JSONObject jsonObject = new JSONObject();
jsonObject.toString();

And if you want to get a specific value, you can use:

jsonObject.getString("msg");

or Integer value

jsonObject.getInt("codeNum");
