{
"data":
{
"map":
{
"allowNestedValues": true,
"create": "2012-12-11 15:16:13",

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.
This should get all the values from the above JsonObject
System.out.println(jsonObj.get("msg"));
System.out.println(jsonObj.get("code"));
JsonObject obj= jsonObj.get("data").getAsJsonObject().get("map").getAsJsonObject();
System.out.println(obj.get("allowNestedValues"));
System.out.println(obj.get("create"));
System.out.println(obj.get("title"));
System.out.println(obj.get("transitions"));
JSONObject metadata = (JSONObject) data.get("map"); //for example
String jsonString = metadata.**toJSONString()**;
You can try Gson convertor, to get the exact conversion like json.stringify
val jsonString:String = jsonObject.toString()
val gson:Gson = GsonBuilder().setPrettyPrinting().create()
val json:JsonElement = gson.fromJson(jsonString,JsonElement.class)
val jsonInString:String= gson.toJson(json)
println(jsonInString)
There is an inbuilt method to convert a JSONObject to a String. Why don't you use that:
JSONObject json = new JSONObject();
json.toString();
I think you need this :
Suppose you have Sample
JSON
like this :
{"ParamOne":"InnerParamOne":"InnerParamOneValue","InnerParamTwo":"InnerParamTwoValue","InnerParamThree":"InnerParamThreeValue","InnerParamFour":"InnerParamFourValue","InnerParamFive":"InnerParamFiveValue"}}
Converted to String :
String response = {\"ParamOne\":{\"InnerParamOne\":\"InnerParamOneValue\",\"InnerParamTwo\":\"InnerParamTwoValue\",\"InnerParamThree\":\"InnerParamThreeValue\",\"InnerParamFour\":\"InnerParamFourValue\",\"InnerParamFive\":\"InnerParamFiveValue\"}} ;
Just replace " by \"
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");
var data= {"data": {"map":{"allowNestedValues": true,"create": "2012-12-11 15:16:13","title": "test201212110004","transitions": []}},"msg": "success","code": "0"}
o/p:
Object {data: Object, msg: "success", code: "0"}
Use JSON.stringify to convert entire data into string like below
var stringData = JSON.stringify(data);
o/p:
"{"data":{"map":{"allowNestedValues":true,"create":"2012-12-11 15:16:13","title":"test201212110004","transitions":[]}},"msg":"success","code":"0"}"
Use JSON.parse to convert entire string object into JSON Object like below
var orgdata = JSON.parse(stringData);
o/p:
Object {data: Object, msg: "success", code: "0"}
you can use
JsonObject.getString("msg");
Add a double quotes outside the brackets and replace double quotes inside the {}
with \"
So: "{\"data\":{..... }"
You can use reliable library GSON
private static final Type DATA_TYPE_JSON =
new TypeToken<JSONObject>() {}.getType();
JSONObject orderJSON = new JSONObject();
orderJSON.put("noOfLayers", "2");
orderJSON.put("baseMaterial", "mat");
System.out.println("JSON == "+orderJSON.toString());
String dataAsJson = new Gson().toJson(orderJSON, DATA_TYPE_JSON);
System.out.println("Value of dataAsJson == "+dataAsJson.toString());
String data = new Gson().toJson(dataAsJson);
System.out.println("Value of jsonString == "+data.toString());
