Json wrong fields

How can I get all wrong fields names? For example, I have next input string as JSON format:
{
"name": "name#1",
"address": "address#1",
"pone": "000000000",
"ail": "mail#smth.ru"
}
Where 'pone' and 'ail' fields are wrong. It needs to use 'phone' and 'email'. I also use this property
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, true);
For catching exception. And I catch it inside of try/catch when deserializing JSON to an object, but there is info about only one field in the exception message.
I need to get all wrong fields at once.
Maybe somebody have an idea about it? I also tried use jsonSchema but I think it isn't good idea, because in the end I have this message $: string found, object expected by this code:
JsonSchemaFactory factory = JsonSchemaFactory.getInstance(VersionFlag.V201909);
InputStream stream=TestClass.class.getResourceAsStream("/file.json");
JsonSchema schema=factory.getSchema(stream);
JsonNode node =mapper.convertToJsonNode(MyObject.builder().build());
Set<ValidationMessage> validationResult = schema.validate(node);

Getting a JSON Array from JSON Object (SOLVED)

First time having to work with JSON data on my own, even if very simple.
Here is the JSON data I'm working with:
{
"heart" : [92, 108],
"temperature" : [85.08, 85.66],
"conductance" : [4095, 4095]
}
What I'm attempting to do is extract one of the three arrays found within that JSON object, but I'm receiving a JSONException: Not a primitive array: class org.json.JSONArray. Here is a portion of the code that I'm using to extract the array of values associated with "heart":
JSONObject obj = new JSONObject(obtainJSONObject());
JSONArray arr = new JSONArray(obj.getJSONArray("heart")); // This is where the error is occuring
int low = arr.getInt(0);
int high = arr.getInt(1);
I've tried to follow what this solution answered, but can't really make much sense of it: How to Get JSON Array Within JSON Object?
I'm not sure if it has something to do with the way how the JSON data is being formatted? I did check online to see if it was any valid or not at https://jsonformatter.curiousconcept.com/. Any help or insights will be greatly appreciated!

Update data stored in ElasticSearch in Java with TransportClient

I'm trying to update data in Elastic Search in my Java program with TranportClient class. I know I can UPDATE in this way :
XContentBuilder builder = XContentFactory.jsonBuilder().startObject()
.field("source.ivarId", source.ivarId)
.field("source.channel", source.channel)
.field("source.bacId", source.bacId).endObject();
UpdateResponse response = client.prepareUpdate(_index, _type, _id).setDoc(builder.string()).get();
while source is my user-defined class which contains 3 fields : ivarId, channel and bacId.
But I want to know is there any method that could do the same thing, but using another more efficient and easier way, so that I don't need to assign each field inside a class? For example, can I do like this?
XContentBuilder builder = XContentFactory.jsonBuilder().startObject()
.field("source", source).endObject();
UpdateResponse response = client.prepareUpdate(_index, _type, _id).setDoc(builder.string()).get();
I tried the latter method, and I got this exception :
MapperParsingException[object mapping for [source] tried to parse field [source] as object, but found a concrete value]
I'm using Java 1.8.0.121, and both versions of ElasticSearch and TransportClient are 5.1. Thanks!

The answer is much more easier than I thought.
Gson gson = new Gson();
String sourceJsonString = gson.toJson(updateContent);
UpdateResponse response = client
.prepareUpdate(_index, "logs", id).setDoc(sourceJsonString).get();
updateContent is the object that contained new data, just to transform it to Json string, then use that to update, done.

Converting JSONObject to JSON using GSON

I am having an Java Object which consist many type of variables including a JSONObject.
Whan i debug my object i got the following String for JSONObject:-
{"INCLUSIONS":{"OPTIONS":[{"display":"Complimentary stay for children under 5 without extra bed"}]}}
But when i used:-gson.toJson(JSONObj),I got following
{"myHashMap":{"INCLUSIONS":{"myHashMap":{"OPTIONS":{"myArrayList":[{"myHashMap":{"display":"Complimentary stay for children under 5 without extra bed"}}]}}}}}
Someone please can elaborate why it is converting JSONObject to Map & list ??
Or Any work Around ??
Thanks.

Just use myJsonObj.toString() instead of myJsonObj.toJSON()
Your problem happens because a JSONObject is stored as a HashMap to allow the programmer to reach values with methods based on keys. As example,
String jsonStr = "{'key': 'value'}";
JsonObject json = gson.fromJson(jsonStr, JsonObject.class);
String value = json.get("key").getAsString();
You can figure that json attributes are stored as a HashMap<JsonElement>

Detect type of JSON attribute

JSON:
{"attribute1":11, "attribute2":"string atribute"}
I want to detect what kind of type are attribute1 and attribute2:
attribute1 is integer
attribute2 is string
jsonObject.getAttributeType("attribute2"); // should output: string/integer/boolean.
It was very easy to achieve in PHP or OBJC. Suggestions?

(I'm assuming that the Android for the org.json package is that same as you can find on the json.org site ... here.)
The only method on a JSONObject that will give you the underlying value ... without coercing it ... is JSONObject.get(name). If name is known, the result is the object that represents the value internally. I haven't done a comprehensive trawl of the code, but I think it can only be one of the following types:
Boolean, Long, Double, String, JSONArray, JSONObject
You should be able to discriminate these using instanceof.
But should be asking yourself if this is the right thing to do. The normal way to deal with JSON object attributes via the JSONObject API is to use the methods that coerce them into the type that you expect. In most cases, it doesn't matter if a number is sent as 42 or 42.0 or "42" ... and it is best not to be picky if the intent is easy to determine.

Another solution you can use the jackson library to do this,
import com.fasterxml.jackson.databind.JsonNode;
import com.github.fge.jackson.JsonLoader;
//Defining the JSON object
JSON json = {"attribute1":11, "attribute2":"string atribute"};
//Get the needed attribute
String value = json.get("attribute1");
//Convert the attribute to JsonNode
JsonNode value = JsonLoader.fromString(value);
//Then you can check type as below
value.isObject();
value.isArray();
value.isDouble();
value.isTextual();
value.isInt()
