Json data not properly reading from URL

Question

I am trying to read Json data from url. On the following json format is not reading correctly as jsonObject from the link. I have code implemented but still getting error. Need some help regarding the error. Note that, I am not creating any model class to parse json data rather I am calling direct from URL and then print that json data in the console.

Json data :

[
    {
        "countryId": "BE",
        "vat": 0.21,
        "maxShortestEdge": 60,
        "maxMiddleEdge": 80,
        "maxLongestEdge": 200,
        "maxLengthGirth": 300,
        "maxWeight": 40,
        "languages": [
            "fr",
            "nl",
            "en"
        ],
        "defaultLanguage": "nl",
        "currency": {
            "id": "EUR",
            "messageId": "general.units.currency.eur"
        }
    },
    {
        "countryId": "DE",
        "vat": 0.19,
        "maxShortestEdge": 60,
        "maxMiddleEdge": 80,
        "maxLongestEdge": 200,
        "maxLengthGirth": 300,
        "maxWeight": 40,
        "languages": [
            "de",
            "en"
        ],
        "defaultLanguage": "de",
        "currency": {
            "id": "EUR",
            "messageId": "general.units.currency.eur"
        },
        "tracking": {
            "google": "UA-64686897-5",
            "facebook": "591925420983129"
        }
    },
    {
        "countryId": "LU",
        "vat": 0.17,
        "maxShortestEdge": 60,
        "maxMiddleEdge": 80,
        "maxLongestEdge": 200,
        "maxLengthGirth": 300,
        "maxWeight": 40,
        "languages": [
            "fr",
            "en"
        ],
        "defaultLanguage": "fr",
        "currency": {
            "id": "EUR",
            "messageId": "general.units.currency.eur"
        }
    }
]

Code Implemented:

public class RestTest {

    public static void main(String[] args) {
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.xxxxx.com",8080));

        try {

            URL url = new URL("http://test.one.de/api/");
            HttpURLConnection  http = (HttpURLConnection)url.openConnection(proxy);
            InputStream ins = http.getInputStream();
            JsonParser jsonParser = new JsonParser();
            JsonObject jsonObject = (JsonObject)jsonParser.parse(new InputStreamReader(ins));
            System.out.println(jsonObject);
        } 
        catch (MalformedURLException e) 
        {
            e.printStackTrace();
        } catch (IOException e) {

            e.printStackTrace();
        }

    }

}

Error getting :

Try to use JsonArray instead of JsonObject. You can try to read string and then convert it

String json = IOUtils.toString(ins, encoding);
JsonArray jsonArray = new JsonArray(json);

You can use ObjectMapper as alternative:

    ObjectMapper mapper = new ObjectMapper();
    JsonNode node = mapper.readTree(json);
    System.out.print(node.get(0).get("countryId").asText()); //getting countryId of the first object in array

you can use following code to parse it

Stri

ng url = "http://qs.gls-one.de/api/countries/origin/configurations";

CloseableHttpClient client = HttpClientBuilder.create().build();
HttpGet post = new HttpGet(url);
HttpResponse response = client.execute(post);
System.out.println("Response Code : "
                + response.getStatusLine().getStatusCode());

String response2= EntityUtils.toString(response.getEntity(), "UTF-8");
JSONArray jsonArray = new JSONArray(response2);
System.out.println(jsonArray);

}
