I'm trying to retrieve the "Maxspeed" string from the JSON below.
It iterates through the array, but when it reaches the "tag" object and tries to retrieve the "maxspeed" value, it returns an exception(below).
Would anyone know why this is happening?
Any help would be appreciated.
Thanks.
Exception:
org.json.JSONException: No value for maxspeed
Java:
JSONObject parentObject = new JSONObject(result);
JSONArray speedJSON = parentObject.getJSONArray("elements");
for (int i = 0; i < speedJSON.length(); i++) {
JSONObject element = (JSONObject) speedJSON.get(i);
if (!element.isNull("tags")) {
//JSONObject tags = (JSONObject) speedJSON.getJSONObject(i).get("tags");
String maxspeed = element.getString("maxspeed");
txtSpeed.setText(maxspeed+" here");
} else {
//Your error handling here...
}
}
//txtSpeed.setText(""+);
this.progressDialog.dismiss();

You are trying to get maxspeed from the element, but it's not there. It is inside tags object in the element.
You need something like this
if (!element.isNull("tags")) {
JSONObject tags = element.getJSONObject("tags");
String maxspeed = tags.getString("maxspeed");
txtSpeed.setText(maxspeed+" here");
} else {
//Your error handling here...
}
String maxspeed = element.getString("maxspeed");
to
String maxspeed = element.getJSONObject("tags").getString("maxspeed");

I'm trying to insert an object to a nested array through the java api, but I get the following error
MapperParsingException[object mapping for [X] tried to parse field [null] as object, but found a concrete value]
doing it through Kibana as shown below the same script works.
Any ideas on how to fix this?
The java code is the following
HashMap<String, Object> params = new HashMap<>();
params.put("object", objectAsString);
Script script = new Script(ScriptType.INLINE, "painless", "ctx._source.media.add(params.object)", params);
UpdateResponse result = elasticClient.prepareUpdate(indexName, "Type", documentId).setScript(script).execute().actionGet();
Trhough Kibana

I did some set of activities on json script. Need to add precondition on it.
how to use precondition on json script.
In precondition, i need to check the mysql db field. once flag as 'Y',

You can use a ShellCommandPrecondition for this which will let you write a custom precondition.

Question:: How to get Bangalore having key adminArea5
It looks like that you've an JSONArray() within your JSONObject.
Try to get the JSONOBject result, pick out the
JSONArray jsonArray = new JSONArray(jsonObject.get("results")).
In your JSONArray you can parse out your required data.
I have the following JSON object below and I was wondering how to fetch the results of MediaUrl. I found a lot of tutorials on how to parse an array or an object but I can't find anything on how to loop an array inside of an object.

Assuming obj is a JSONObject obtained by parsing the posted String
"results" is the key to a JSONArray that you get from your object using
JSONArray results = obj.getJSONObject("d").getJSONArray("results")
JSONArray has get*(int index) for each type of data you can encounter.
In your case, "results" is an array of JSONObject. You can loop through it using :
for (int i = 0; i < results.length(); i++) {
JSONObject oneResult = results.getJSONObject(i);
}
Once you have the JSONObject, the MediaUrl is just one getString("MediaUrl") away ...
