Parsing JSONObject to access ID when there are multiple ID values (Java)

I am obtaining a JSON response from an API that gives me a list of call records formatted as JSON. I want to parse through the data and find the record ID, my trouble is that each JSON record has multiple ID's and I am not sure how to access the correct one. Keep in mind, I do not know the value of the ID is "3461487000073355176" prior to running the request.
This is my code to receive the JSON, I created a JSONObject so I can hopefully store the value.
1.
Response response = client.newCall(request).execute();
String responseBody = response.body().string();
Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonParser parser = new JsonParser();
JsonElement je = parser.parse(responseBody);
String prettyJsonString = gson.toJson(je);
JSONObject json = new JSONObject(prettyJsonString);
System.out.println("Json = " + json);
The JSON the ID I need to access has a comment next to it:
"data": [
{
"Owner": {
"name": "My namen",
"id": "346148700000017",

If I understood it correctly, you can get the id like this:
Here, json has the following value.
[
{
"Owner": {
"name": "My namen",
"id": "346148700000017",
"email": "m#gmail.com"
},
"id": "**3461487000073355176**"
...
}
]
Now I can iterate over JSONArray to get the id.
JSONArray jsonArray = new JSONArray(json);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = (JSONObject) jsonArray.get(i);
String id = (String) jsonObject.get("id");
System.out.println(id);
}
It prints out **3461487000073355176**.
You can do jsonObject.getJSONArray("data"); in your example to obtain JSON array.

The posted JSON response is missing the initial "{".
Your JSON contains data, which is a JSONArray of Owner objects. To get the id field of the first owner (array element 0):
// existing code
JSONObject json = new JSONObject(prettyJsonString);
System.out.println("Json = " + json);
// get the id field
JSONArray dataArray = (JSONArray)json.get("data");
JSONObject data0 = (JSONObject) dataArray.get(0);
JSONObject owner = (JSONObject) data0.get("Owner");
String id = owner.getString("id");
System.out.println(id);

Not sure if understood correctly but if you need to get all the IDs in that "level" why don't you try to model it as a class instead of using parser and let Gson do the parsing (this class might be useful later if you need to add more details)?
For example, defining something like this:
#Getter #Setter
// This models the response string from body
public class Response {
#Getter #Setter
// This models objects in the data list/array
public static class IdHolder {
// Only id because not interested of the rest
private String id;
}
// Only list of id holders because not interested of the rest
private List<IdHolder> data;
}
Then it would be as easy as:
Response res = gson.fromJson(responseBody, Response.class);
// Print out what you got
res.getData().stream().map(IdHolder::getId).forEach(System.out::println);

Want to read JSONArray with JSONObject, but got the error A non-empty JSON Pointer

My Json FILE (it´s an array! )
[
{
"datasetid": "country-flags",
"recordid": "d661d0a8676bf4d7563114c1d9c465987df22132",
"fields": {
"num_un": 32,
"geolocation": [
-38.416097,
-63.616672
],

"a3_un": "ARG",
"country": "Argentina",
"flag": {
"mimetype": "image/png",
"format": "PNG",
"filename": "ar.png",
"width": 16,
"id": "fceb4235ce95c8597bfa77d0db0181a0",
"height": 11,
"thumbnail": true
},
"a2_iso": "AR"
},
"geometry": {

]
},
"record_timestamp": "2016-09-26T07:48:38.162+02:00"
},
more...
]
So i want to get the value from coordinates. So for this i tried to work with this:
JsonReader jsonReader = Json
.createReader(new FileReader(getClass().getResource("country-flags.json").getPath()));
JsonArray arr = jsonReader.readArray();
for(int i = 1; i<arr.size();i++)
{
JsonObject obj = arr.getJsonObject(i);
System.out.println("coordinates: " + obj.containsKey("\"coordinates\""));
System.out.println("##########");
System.out.println(obj.getValue("\"coordinates\""));
}
But i got the error:
javax.json.JsonException: A non-empty JSON Pointer must begin with a
'/'
Can someone help me out ?!

Your code obj.containsKey("\"coordinates\"") will return false as coordinates is NOT a top level key, but is a 2nd level (nested) key. If you print obj.keySet(), you will get [datasetid, recordid, fields, geometry, record_timestamp] (first / top level keys only).
If the structure of your JSON is fixed, you can use the following code:
for(int i = 1; i<arr.size();i++)
{
JsonObject obj = arr.getJsonObject(i);
JsonObject jsonChildObject = obj.getJsonObject("geometry");
if(jsonChildObject.containsKey("coordinates"))
System.out.println(jsonChildObject.getValue("/coordinates"));
}
Notice the / in front of the getValue method's coordinates param. I think that was the reason you were here in the first place.

how to get elements from JSONObject and write it to file

i have a following JSONObject
{"elements": [
{
"name": "StartLabelFormat",
"value": "^XA"
},
{
"name": "shipperAddressLine1",
"value": "Street1",
"format": {"Text": {
"orientation": "N",
"height": "28",
"width": 20,
"fontname": 0,
"y": 373,
"x": 20
}}
},
{
"name": "EndLabelFormat",
"value": "^XZ"
}
]}
Now i want to get element from this Object and write it to a file.
For Example, for this block
{
"name": "shipperAddressLine1",
"value": "Street1",
"format": {"Text": {
"orientation": "N",
"height": "28",
"width": 21,
"fontname": 0,
"y": 373,
"x": 20
}}
},
I want to write in file as
^FT 20, 373 ^A0N, 28, 21 ^FDStreet1^FS.
Please help me to do this.

How to do it ?
If you meet {} in your code , you can use JSONObject to parse it .
If you meet [] in your code , you can use JSONArray to parse it .
And if you meet [] in your code , you can use for loop to get value in it .
And you should use try catch in your code .
Try this in your code .
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray elements = jsonObject.getJSONArray("elements");
for (int i = 0; i < elements.length(); i++) {
JSONObject jsonObject1 = elements.getJSONObject(i);
String name = jsonObject1.optString("name");
String value = jsonObject1.optString("value");
JSONObject format = jsonObject1.optJSONObject("format");
JSONObject Text = format.optJSONObject("Text");
String orientation = Text.optString("orientation");
String height = Text.optString("height");
String width = Text.optString("width");
}
} catch (JSONException e) {
e.printStackTrace();
}
Note
And use optString and optJSONObject in your code . If format is null ,it will not return error .
And you can judge that JSONArray's length is not 0 and not null in the code .

To get this element from JsonArray
JsonObject yourElement = yourJsonArray.get(index);
Simply, you can use gson library for parsing json to objects.
public class Staff {
private String name;
private String value;
//...
and use Gson
String jsonInString = " {
"name": "shipperAddressLine1",
"value": "Street1"
}";
Staff staff = gson.fromJson(yourElement.toString() , Staff.class);
After that you can write in file by using your custom toString() method inside Staff class.
P.S. to convert JsonObject to String you can use also toString() method.

JSON: Get list of JSON Objects

In java how can I pull out the JSON objects enclosed in the "{}"?
I have tried:
JSONObject obj = new JSONObject(jstring);
obj.getJSONArray("fileName");
But it only return the first object. How do I get a list with both objects?
JSON:
[
{
"fileName": [
"file1"
],
"date": [
"8/25/2015 0:00"
],
"time": [
"7/16/2009 16:51"
],
"id": "1",
"version_": 1
},
{
"fileName": [
"file1"
],
"date": [
"8/25/2015 0:00"
],
"time": [
"7/16/2009 16:51"
],
"id": "1",
"version_": 1
}
]

Your root JSON is an Array, so first create a JSONArray from your String.
Do this:
JSONArray arr = new JSONArray(jstring);
for (int i = 0; i < arr.length(); i++) { // Walk through the Array.
JSONObject obj = arr.getJSONObject(i);
JSONArray arr2 = obj.getJSONArray("fileName");
// Do whatever.
}
For more info, please refer to the docs on JSONArray and JSONObject.

You have to directly construct JSONArray from JSON string in this case.
JSONArray arr = new JSONArray(jstring);

JSONArray jsonArray = new JSONArray(jstring);

Problems parsing JSON in Java

I have this json:
[{
"name": "prog 1",
"show": [{
"name": "n1",
"time": "01.10 "
}, {
"name": "n2",
"time": "01.35 "
}]
}, {
"name": "prog 2",
"show": [{
"name": "n1",
"time": "01.10 "
}, {
"name": "n2",
"time": "01.35 "
}]
}]
Now trying to parse it in Java like:
JSONObject json=new JSONObject(json_str);
throws an Exception, since it doesn't begin with {, but [ since it's an array. I can parse this without problem in js, but aparently I cannot load an JSONArray with this string...

use: JSONArray objArray = new JSONArray (json_str);
// to access the individual objects inside the array:
for(int i=0;i<objArray.length();i++)
{
JSONObject obj = objArray.getJSONObject(i);
}

Have you tried this:
JSONArray arr = new JSONArray(stringWithContent);
Then access it like :
for(int i = 0; i<arr.length();i++){
System.out.println(arr.get(i));
}

You can try following code
JSONObject jObject = new JSONObject(json_str);
JSONArray array = jObject.getJSONArray("show");
for(int i = 0 ; i < array.length() ; i++)
{
System.out.println(array.getJSONObject(i).getString("name"));
System.out.println(array.getJSONObject(i).getString("time"));
}
It will helpful ...
