I am gettion json response in Object but i want to be in Json Array

I am getting list of coins from API https://min-api.cryptocompare.com/data/all/coinlist?api-key.
It returns json response like this -

When I am generating pojo class for it, it is creating class _42 as well as class _300 means for every object it is creating new class.
Here it is :-

I want json to be in Array response. How can I do this?
ApiService class looks like -
#GET("/data/all/coinlist")
Call<CoinBean> getCurrencyList(
#Query("api_key") String apiKey
);

u can create below class structure to de serialize at ur side.
Class Data {
List<Map<String, ImageInfo>> body = new ArrayList()
}

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $

Ok, So I read a couple other questions with this same error, but none have been answered as working, and doesnt seem like I can get it working.
I am connecting to google in-app billing and have everything set up, but, when I try to pull my skudetails (I have 2 SKUs there now), I get the error -
Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $
I have a SubscriptionActivity, Result (serializable), and Details model class (serializable). Below is the code, any help will be great, thanks-
From subscriptionactivity:
Gson gson = new Gson();
try {
Result result = gson.fromJson(skuDetailsList.toString(), Result.class);
if (result != null) {
for (Details d : result.getDetails()) {
System.out.println(d.getProductId()
+ " \n " + d.getTitle() + " \n " + d.getDescription() + " \n "
+ d.getPrice());
}
}
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
From details model:

}
/**

*/
public void setDetails(ArrayList<Details> details) {
this.details = details;
}
}*
Oh..and the response I was trying to parse (skuDetailsList.toString()) is:
[
SkuDetails: {
"productId": "basic_sub",
"type": "subs",
"price": "$0.99",
"price_amount_micros": 990000,
"price_currency_code": "USD",
"subscriptionPeriod": "P1M",
"freeTrialPeriod": "P4W2D",
"title": "Basic Subscription Service (DadBod Recipes)",
"description": "Basic Subscription Service for DadBodRecipes"
},
SkuDetails: {
"productId": "enterprise_sub",
"type": "subs",
"price": "$2.99",
"price_amount_micros": 2990000,
"price_currency_code": "USD",
"subscriptionPeriod": "P1M",
"freeTrialPeriod": "P4W2D",
"title": "Enterprise Subscription Service (DadBod Recipes)",
"description": "Enterprise Subscription Service for DadBodRecipes"
}
]

Issue is because, the result you're getting is as <Key-Value> pair (not as JSON object/Array, but similar to it).
So you'll need to make it to JSONObject first and then parse it using Gson like below:
Map<String, String> params = skuDetailsList;
JSONObject object = new JSONObject(params);
Result result = gson.fromJson(object.toString(), Result.class);
Do like this, hope it helps !

You are trying to parse your json
[
as
{
when you see the [ it represents a list
when you see the { it represents an object.
I'm pretty sure you know that as you built a wrapper class, but your wrapper class is also an object, not an array.
So your choices are to have your wrapper class extend ArrayList or some form of List.
Or
Tell your Json converter that the base is an Array and you want the first object in the list is an object of your type.

how to access to json with java

I have in a rest response this json:
{
"TRANS": {
"HPAY": [
{
"ID": "1234",
"DATE": "10/09/2011 18:09:27",
"REC": "wallet Ricaricato",
"COM": "Tasso Commissione",
"MSG": "Commento White Brand",
"STATUS": "3",
"EXTRA": {
"IS3DS": "0",
"CTRY": "FRA",
"AUTH": "455622"
},
"INT_MSG": "05-00-05 ERR_PSP_REFUSED",
"MLABEL": "IBAN",
"TYPE": "1"
}
]
}
}
I have made pojo class to map this json in java.
public class Trans {
private List<Hpay> hpay;
public Trans(){
}
//getter and setter
}
public class Hpay {
private String id;
private String date;
private String com;
private String msg;
private String status;
private List<Extra> extra;
private String int_msg;
private String mlabel;
private String type;
public Hpay(){
}
//getter and setter
}
I try to map the object with Gson library.
Gson gson=new Gson();
Trans transaction=gson.fromJson(response.toString(), Trans.class);
If i call hpay method on transaction i have null..i don't know why...

I have deleted previous answer and add new one as par your requirement
JSON String :
{
"TRANS": {
"HPAY": [{
"ID": "1234",
"DATE": "10/09/2011 18:09:27",
"REC": "wallet Ricaricato",
"COM": "Tasso Commissione",
"MSG": "Commento White Brand",
"STATUS": "3",
"EXTRA": {
"IS3DS": "0",
"CTRY": "FRA",
"AUTH": "455622"
},
"INT_MSG": "05-00-05 ERR_PSP_REFUSED",
"MLABEL": "IBAN",
"TYPE": "1"
}
]
}
}

private Trans trans;
public Trans getTRANS() {return trans;}
public void setTRANS(Trans trans) {this.trans = trans;}
}
public class Trans {

private List<HPay> hPay;
public List<HPay> getHPAY() {return hPay;}
public void setHPAY(List<HPay> hPay) {this.hPay = hPay;}

public class Extra {
#SerializedName("IS3DS")
#Expose
private String is3ds;
#SerializedName("CTRY")
#Expose
private String ctry;
#SerializedName("AUTH")
#Expose
private String auth;
public String getIS3DS() { return is3ds; }
public void setIS3DS(String is3ds) { this.is3ds = is3ds; }
public String getCTRY() { return ctry; }
public void setCTRY(String ctry) { this.ctry = ctry; }
public String getAUTH() { return auth; }
public void setAUTH(String auth) { this.auth = auth; }
}
Conversion Logic :
import com.google.gson.Gson;
public class NewClass {
public static void main(String[] args) {
Gson g = new Gson();
g.fromJson(json, MyObject.class);
}
static String json = "{ \"TRANS\": { \"HPAY\": [{ \"ID\": \"1234\", \"DATE\": \"10/09/2011 18:09:27\", \"REC\": \"wallet Ricaricato\", \"COM\": \"Tasso Commissione\", \"MSG\": \"Commento White Brand\", \"STATUS\": \"3\", \"EXTRA\": { \"IS3DS\": \"0\", \"CTRY\": \"FRA\", \"AUTH\": \"455622\" }, \"INT_MSG\": \"05-00-05 ERR_PSP_REFUSED\", \"MLABEL\": \"IBAN\", \"TYPE\": \"1\" } ] } }";
}
Here I use Google Gosn lib for conversion.
And need to import bellow classes for annotation
com.google.gson.annotations.Expose;
com.google.gson.annotations.SerializedName;

First parse the json data using json.simple and then set the values using setters
Object obj = parser.parse(new FileReader( "file.json" ));
JSONObject jsonObject = (JSONObject) obj;
JSONArray hpayObj= (JSONArray) jsonObject.get("HPAY");
//get the first element of array
JSONObject details= hpayObj.getJSONArray(0);
String id = (String)details.get("ID");
//set the value of the id field in the setter of class Trans
new Trans().setId(id);
new Trans().setDate((String)details.get("DATE"));
new Trans().setRec((String)details.get("REC"));
and so on..
//get the second array element
JSONObject intMsgObj= hpayObj.getJSONArray(1);
new Trans().setIntmsg((String)details.get("INT_MSG"));
//get the third array element
JSONObject mlabelObj= hpayObj.getJSONArray(2);
new Trans().setMlabel((String)details.get("MLABEL"));
JSONObject typeObj= hpayObj.getJSONArray(3);
new Trans().setType((String)details.get("TYPE"));
Now you can get the values using your getter methods.

Looping through Multiple JSON Objects in Android

I'm trying to parse a JSON object, part of which looks like this :
{

"message":"OK"
},
"data":{
"0":{
"SubFranchiseID":"0",
"OutletID":"607",

},
{
"OfflineCategoryID":"17",
"Name":"Italian",
"ParentCategoryID":"1",

},
{
"OfflineCategoryID":"1",
"Name":"Restaurant",
"ParentCategoryID":null,
"CategoryType":""
},
{
"OfflineCategoryID":"21",
"Name":"North Indian",

}
],

},

.
.

}
}
There are nearly 35 Json objects and nested JsonArrays for each of these objects.I'm trying to get data like this :
url = new URL(uri);
URLConnection connection = url.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
reader.close();
json =sb.toString();
JSONObject sjson=json.getJSONObject("data");
Log.d("sjson values-->",sjson+"--");
**JSONObject ssjson=sjson.getJSONObject("0");**
And now i am getting each of values like this :
String outletName = ssjson.getString("OutletName");
My question is there any better way (loop) through all objects ( 0,1,...35) and get data for each individual object separately.

Example json
{
"status": {
"rcode": "200",
"message": "Good, you got me!!!"
},
"data": [
{
"SubFranchiseID": "0",
"OutletID": "607",
"OutletName": "Spill",
},
{
"SubFranchiseID": "0",
"OutletID": "607",
"OutletName": "Spill"
}
]
}
Represent the json in terms of plain java classes with getter and
setters
First create a the root class (for the root object)
public class Root {
//For the status object
private Status status;
//For the array of data objects
private List<Data> data;
//create setters and getters for the two properties.
}
public class Status {
private String rcode;
//this maps to the rcode in the status object in json
private String message;
//create setters and getters for the two
}
public class Data {
private String SubFranchiseID;
private String OutletID;
private String OutletName;
//create setters and getters for these properties.
}
Now, lets do the magic with gson (The serialization of the json in to the ready made classes)
reader.close();
json =sb.toString();
Root root = new Gson().fromJson(response, Root.class);
//get the rcode
if(root.getStatus().getrCode().equalsIgnoreCase("200"))
{
//print the data.
for(Data d : root.getData()) {
System.out.println(d.getSubFranchiseID()+"-"+d.getOutletID()+"-"+d.getOutletName());
}
}
A small note for using gson.
1.) The property names inside the classes should match the property in the json or else use a `#SerializeName("propertyname")`.
2.) An array of objects would map to List<YourObject> , for eg : the data property in the json.
3.) You can have default value for your properties without creating getters and setters for them like
private boolean isJson = true;

Thanks for the help. I have a lot of json objects inside "data" -> "0" like "Outletname","OutletID ",etc , before Json Array ( "Categories" ). i have created a model class for my data. Now i want to itterate json objects data using Gson.Part of my json data

"SubFranchiseID":"0",

Retrofit: Problems handling array or single object

I have been following other answers but there is a missing step that i cant find which is resulting in call being successful but the data not being parsed correctly because the first call i make returns a list of objects but only 1 object is returned which is all null
MyModel.java
public class MyModel {
#SerializedName("url")
private String mUrl;
#SerializedName("name")
private String mName;
#SerializedName("description")
private String mDescription;
}
MyModelDeserializer.java
This just checks if its array or object and will simply return the array
public class MyModelTypeAdapter implements JsonDeserializer<ArrayList<MyModel>>{
#Override
public ArrayList<MyModel> deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
ArrayList<MyModel> objects = new ArrayList<>();
if(json.isJsonArray()){
for(JsonElement e : json.getAsJsonArray()){
objects.add((MyModel)context.deserialize(e,MyModel.class));
}
}else if(json.isJsonObject()){
objects.add((MyModel)context.deserialize(json,MyModel.class));
}
return objects;
}
}
Some other stuff
Gson gson = new GsonBuilder()
.registerTypeAdapter(new TypeToken<ArrayList<MyModel>>() {}.getType(), new MyModelTypeAdapter())
.create();
restAdapter = new RestAdapter.Builder()
.setEndpoint(BuildConstants.BASE_URL)
.setConverter(new GsonConverter(gson))
.setClient(new OkClient(okHttpClient))
.setLogLevel(RestAdapter.LogLevel.FULL)
.build();
This is the part which confusing me, what do i put as the return type of the callback
#GET(URLConstants.LIST_URL)
void getData(Callback<ArrayList<MyModel>> callback);
Edit JSON data
{
"places": [
{
"url": "www.google.com",
"name": "Google",
"description": "Search engine"
},
{
"url": "www.Facebook.com",
"name": "Facebook",
"description": "Social Network"
},
{
"url": "www.amazon.com",
"name": "Amazon",
"description": "Shopping"
}
]
}

First create a POJO class to handle json. You can use jsonschema2pojo to create pojo class for your json:
public class MyModel {
#Expose
private List<Place> places = new ArrayList<Place>();
/**
*
* #return
* The places
*/
public List<Place> getPlaces() {
return places;
}
/**
*
* #param places
* The places
*/
public void setPlaces(List<Place> places) {
this.places = places;
}
}
public class Place {
#Expose
private String url;
#Expose
private String name;
#Expose
private String description;
/**
*
* #return
* The url
*/
public String getUrl() {
return url;
}
/**
*
* #param url
* The url
*/
public void setUrl(String url) {
this.url = url;
}
/**
*
* #return
* The name
*/
public String getName() {
return name;
}
/**
*
* #param name
* The name
*/
public void setName(String name) {
this.name = name;
}
/**
*
* #return
* The description
*/
public String getDescription() {
return description;
}
/**
*
* #param description
* The description
*/
public void setDescription(String description) {
this.description = description;
}
}
Next create a restadapter like this:
public class SimpleRestClient {
private SimpleRestApi simpleRestApi;
public SimpleRestClient() {
RestAdapter restAdapter = new RestAdapter.Builder()
.setLogLevel(RestAdapter.LogLevel.FULL)
.setEndpoint(Constants.BASE_URL)
.build();
simpleRestApi = restAdapter.create(SimpleRestApi.class);
}
public SimpleRestApi getSimpleRestApi() {
return simpleRestApi;
}
}
Now to create the api interface. Here we are setting our POJO class to handle the json response:
public interface SimpleRestApi {
#GET("Enter URL")
public void getSimpleResponse(Callback<MyModel> handlerCallback);
}
Finally call it as follows:
simpleRestApi = new SimpleRestClient().getSimpleRestApi();
simpleRestApi.getSimpleResponse(new Callback<MyModel>() {
#Override
public void success(MyModel responseHandler, Response response) {
// here you can get your url, name and description.
}
#Override
public void failure(RetrofitError error) {
progress.dismiss();
Log.e("CLASS", "JSON: " + error.getCause());
}
});
