I can't seem to get the selection of elements in the array right. Or the syntax swears or something else. Here is what I am trying
{
"info": "info",
"user":[{
0:
"info":{
"name": "user 1"
}
}]
}
Here is my code and what i am trying to do
JSONObject jsonObject = new JSONObject(json_string);
System.out.println(jsonObject.getJSONArray("user").getJSONArray(0).getJSONArray("info").getString("name"));
And I don't get anything. Who can tell me how to do it right

Thanks everyone. I figured out how to do it here is the code)
JSONObject obj = new JSONObject(json_string);
JSONArray userArray = obj.getJSONArray("user");
JSONObject userInfo = userArray.getJSONObject(0).getJSONObject("info");
String reciver = userInfo.getString("name");

How to get data from JSONObject in Java

I am new in Java and I try to search and try many ways to get USER_NAME and PASSWORD in JSONObject
here my code:
JSONObject data = new JSONObject();
JSONObject input = inputHeader.generateInputHeader("ABCD001");
JSONObject jsonResponse = requestService.startRequestTransactionHttp(input);
if(jsonResponse.getString("RES_ID").toString().equals("000")) {
//here I want get USER_NAME and PASSWORD
}
Here is what jsonResponse respond
{ "RES_ID" : "000", "DATA" : { "PASSWORD" : "123456", "USER_NAME" : "abcd" }, "RES_MSG" : "OK!"}
please help me to solve it.

From docs, you should use:
JSONObject data = jsonResponse.getObject("DATA");
String username = data.getString("USER_NAME");
String password = data.getString("PASSWORD");

You can use following to access the nested objects -
JSONObject data= jsonResponse.getJSONObject("DATA");
data.getString("USER_NAME");
data.getString("PASSWORD");

Convert JSON response to Array format in Android

I am getting response from server in JSONArray format. I am not able to retrieve the contents of array also my JSONArray has no Square brackets.
I am passing the response in php as json_encode($array) in server side
response {
community = “worker”
communitystr = "<null>";
workspace = abs;
email = "<null>";
admin = false;
persona = "<null>";
userinfo = {
info = {
contact1 = {
firstname = “jon”;
lastname = “Doe”
phone = “9885678905”;
objectname = contact;
id = 9;
};
event1 = {
eventname = “party”;
description = "";
order = 6;
id = 4;
objectname = events;
};
files = {
filename = “sample”;
description = "";
order = 11;
id = 11;
objectname = files;
};
};
};
};
I checked many links and all have used JSONObject(). But same is not working for me.
How do I get each values in this JSON Response ?

You have to use
: instead of =
, instead of ;
...
Watch out following format:
{
"Herausgeber": "Xema",
"Nummer": "1234-5678-9012-3456",
"Deckung": 2e+6,
"Waehrung": "EURO",
"Inhaber":
{
"Name": "Mustermann",
"Vorname": "Max",
"maennlich": true,
"Hobbys": [ "Reiten", "Golfen", "Lesen" ],
"Alter": 42,
"Kinder": [],
"Partner": null
}
}
Your code seems like to be more JavaScript-Object like :-)

Your response is not valid JSON object.
You can validate the JSON via some online tool, like http://jsonlint.com/
Full specification can be found in RFC 7159 https://www.rfc-editor.org/rfc/rfc7159.
Basically you should look how to encode the values into JSON format in correct way. For that you can refer to PHP Array to JSON Array using json_encode();

Unable to get json parsing for specific field name

I am working on Yahoo Finance. Trying to parse json data from a url, such as Google finance data.
I am fetching data into a string "str" and then parsing the json data to reach the name field inside resources.
the json data is :
{
"list":{
"meta":{
"type":"resource-list",
"start":0,
"count":1
},
"resources":[
{
"resource":{
"classname":"Quote",
"fields":{
"name":"Alphabet Inc.",
"price":"710.489990",
"symbol":"GOOGL",
"ts":"1452891600",
"type":"equity",
"utctime":"2016-01-15T21:00:00+0000",
"volume":"3833751"
}
}
}
]
}
}
I am trying to use this code, but it is not working - need to reach the "name" field:
str4 = Client.execute(httpget, responseHandler);
//str holds the json data given above- checked.
JSONObject str1 = new JSONObject(str4);
JSONObject list = str1.getJSONObject("list");
JSONArray resources = list.getJSONArray("resorces");
JSONObject fields = resources.getJSONObject(1);
str2 = fields.getString("name");

I notices three issues with your code:
you have one item in your JSONArray, so you should retrieve item 0, not item 1.
you misspelled the word resources in your code.
Also, I think you didn't retrieve the fields correctly. This should do it:
JSONObject str1 = new JSONObject(str4);
JSONObject list = str1.getJSONObject("list");
JSONArray resources = list.getJSONArray("resources");
JSONObject fields = resources.getJSONObject(0).getJSONObject("resource").getJSONObject("fields");
str2 = fields.getString("name");

JSON Parsing in Android (Flickr API)

I've been looking extract image urls from the Flickr api for my android application.
More specifically, I need to parse the first owner and first id field for the following JSON
http://pastebin.com/NVKXdELx
Hence, I tried
JSONObject json = new JSONObject(jsonString);
JSONObject photos = json.getJSONObject("photos");
JSONObject photo = photos.getJSONObject("photo");
String picOwner = photo.getString("owner");
String picID = photo.getString("id");
To me, the logic makes sense (grab the row photos, then grab the row photo, then extract the owner field as a string). However, an error is thrown on
JSONObject photo = photos.getJSONObject("photo");
Am I overlooking something?
Note: The ultimate values I am looking for are
"id": "8637130199",
"owner": "93693022#N07"

The element identified by "photo" is a JSON Array, you need to use the JSONArray class
JSONObject json = new JSONObject(jsonString);
JSONObject photos = json.getJSONObject("photos");
JSONArray photo = photos.getJSONArray("photo");
if (photo.length() > 0) {
JSONObject first = photo.getJSONObject(0);
String picOwner = first.getString("owner");
String picID = first.getString("id");
}
