Write arrayList< model class> into txt file using BufferedWriter

I'm trying to get the data from the arrayBundlePack after getting data from enqueue call, I'm trying to use BufferedWriter to the saved data in the arrayBundlePack & write in the txt file, but it just won't get the output I wanted.
I'm not sure if that's the way to output an arrayList model class.
Here's the code
private ArrayList<BundlePack> arrayBundlePack;
Call<BundlePackRepo> call = .............. // api content
call.enqueue(new Callback<BundlePackRepo>() {
#Override
public void onResponse(Call<BundlePackRepo> call, retrofit2.Response<BundlePackRepo> response) {
if (response.isSuccessful()) {
BundlePackRepo repos = response.body();
BundlePackRepo.bundlepacks[] bundlePacksarray;
bundlePacksarray = repos.getBundlePacks();
BundlePack bundlePack;
for (int a = 0; a < bundlePacksarray.length; a++) {
bundlePack = new BundlePack();
bundlePack.setPromotion_kit(bundlePacksarray[a].getPromotion_kit());
bundlePack.setStock_code(bundlePacksarray[a].getStock_code());
bundlePack.setIssue_ref(bundlePacksarray[a].getIssue_ref());
bundlePack.setQuantity(bundlePacksarray[a].getQuantity());
String sysMod = bundlePacksarray[a].getSys_mod();
String modifyDate = bundlePacksarray[a].getModify_dt();
try {
bundlePack.setSys_mod(df.parse(sysMod));
bundlePack.setModify_dt(df.parse(modifyDate));
} catch (java.text.ParseException e) {
e.printStackTrace();
}
bundlePack.setStatus(bundlePacksarray[a].getStatus());
arrayBundlePack.add(bundlePack);
//Trying to put out the data to text file
String filename = "bundlepack.txt";
File txtData = new File(getApplicationContext().getFilesDir(), filename);
FileWriter txtWriter = null;
try {
txtWriter = new FileWriter(txtData);
BufferedWriter fileWriter = new BufferedWriter(txtWriter);
for (BundlePack bdpack : arrayBundlePack) {
fileWriter.write(bdpack.toString());
fileWriter.newLine();
fileWriter.flush();
}
} catch (IOException e) {
e.printStackTrace();
}
}

You are calling toString() to convert each bundlepack instance to a string for output. So you need to an override for toString to the bundlepack class. It needs to format the instance in the form that you need for your purposes.
Since you currently haven't overridden that method, your code is currently calling Object.toString() ... which only outputs the object's class name and hashcode.
Your IDE may well have a helper to generate a toString for a class, based on the fields of the class.

How to get the covid info of a country with java, JSON

I am making a java file in which you enter the country and then it shows you the covid-19 info of that country. The site which I am using is https://covid19.mathdro.id/api/countries/
here i want it such that the user enter the country and it adds the countries name to the website eg if the user entered India it should do this
https://covid19.mathdro.id/api/countries/India
Any help would be neccessary, Thanks

You can use Retrofit to call the APIs
import okhttp3.OkHttpClient;
import retrofit2.Call;
import retrofit2.GsonConverterFactory;
import retrofit2.Retrofit;
import retrofit2.Response;
public class Retrofit_Example {
public static void main(String[] args) {
OkHttpClient.Builder client = new OkHttpClient.Builder();
Retrofit retrofit = new Retrofit.Builder().baseUrl("https://covid19.mathdro.id/")
.addConverterFactory(GsonConverterFactory.create())
.client(client.build())
.build();
Service service = retrofit.create(Service.class);
Call<Response1> responseCall = service.getData("India");
try {
Response<Response1> response = responseCall.execute();
Response1 apiResponse = response.body();
System.out.println(apiResponse);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
You will have to create POJOs from the JSON response coming from the api first and also the retrofit client.
POJO for respone
public class Response1 {
private Confirmed confirmed;
private Deaths deaths;
private String lastUpdate;
private Recovered recovered;
public Confirmed getConfirmed() {
return confirmed;
}
public void setConfirmed(Confirmed confirmed) {
this.confirmed = confirmed;
}
public Deaths getDeaths() {
return deaths;
}
public void setDeaths(Deaths deaths) {
this.deaths = deaths;
}
public String getLastUpdate() {
return lastUpdate;
}
public void setLastUpdate(String lastUpdate) {
this.lastUpdate = lastUpdate;
}
public Recovered getRecovered() {
return recovered;
}
public void setRecovered(Recovered recovered) {
this.recovered = recovered;
}
#Override
public String toString() {
return "Response1{" +
"confirmed=" + confirmed +
", deaths=" + deaths +
", lastUpdate='" + lastUpdate + '\'' +
", recovered=" + recovered +
'}';
}
}
public class Recovered {
private String detail;
private Long value;
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail;
}
public Long getValue() {
return value;
}
public void setValue(Long value) {
this.value = value;
}
#Override
public String toString() {
return "Recovered{" +
"detail='" + detail + '\'' +
", value=" + value +
'}';
}
}
public class Deaths {
private String detail;
private Long value;
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail;
}
public Long getValue() {
return value;
}
public void setValue(Long value) {
this.value = value;
}
#Override
public String toString() {
return "Deaths{" +
"detail='" + detail + '\'' +
", value=" + value +
'}';
}
}
public class Confirmed {
private String detail;
private Long value;
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail;
}
public Long getValue() {
return value;
}
public void setValue(Long value) {
this.value = value;
}
#Override
public String toString() {
return "Confirmed{" +
"detail='" + detail + '\'' +
", value=" + value +
'}';
}
}
Retrofit Client
public interface Service {
#GET("/api/countries/{country}")
public Call<Response1> getData(#Path("country")String country);
}

how to get the specific value of JSON response from JAX-RS ?

I am using JAX-RS with jersey 1.6 to consume the API. i have so far been able to consume it but now i need some specific values only.
how i am consuming api:-
ClientResponse ebpResonse = ebpResource.type("application/json")
.header(HttpHeaders.AUTHORIZATION, token)
.post(ClientResponse.class, ebpReq1);
System.out.println("ebp response is: " + ebpResonse.getEntity(String.class));
i receive response which looks like this:-
{
"code": "2075-4673",
"data": {
"requestId": 4673,
"requestCode": "2075-4673",
"fiscalYear": {
"fiscalYearId": 2075,

},

}
]
},
"message": "Voucher has saved sucessfully.",
"token": "xxxxxxxxxxxxxxxxxxxx",

}
this response for me contains too many unnecessary information too. i need to get epbNo, token, pan in some separate variable. how can i achieve it ?

Just maintain null values in your code, and import gson-2.7.jar

JSON mapping to Java returning null value

I'm trying to map JSON to Java using gson.I was succesful in writing the logic but unsuccesful in getting the output.Below posted are my JSON and Java files.Any help would be highly appreciated.
This is the output i'm getting
value:null
Below posted is the code for .json files
{
"catitem": {
"id": "1.196289",
"src": "http://feeds.reuters.com/~r/reuters/MostRead/~3/PV-SzW7Pve0/story06.htm",

"body": {
"bpart": [
"KUBINKA,dvdvdvdvgbtgfdnhfbnrtdfbcv dbnfg"
]
}
}
}
Below posted is my .java file
public class offc {
public static void main(String[] args) {
JsonReader jr = null;
try {
jr = new JsonReader(new InputStreamReader(new FileInputStream(
"C:\\Users\\rishii\\IdeaProjects\\rishi\\src\\file3.json")));
} catch (Exception ex) {
ex.printStackTrace();
}
Doll s = new Doll();
Gson g = new Gson();
Doll sr1 = g.fromJson(jr, Doll.class);
System.out.println(sr1);
}
}
Below posted is the code for Doll.java
class Doll {
private catitem ct;
public void setCt(catitem ct) {
this.ct = ct;
}
public catitem getCt() {

return summary;
}
public void setBer(body ber) {
this.ber = ber;
}
public body getBer() {
return ber;
}
#Override
public String toString() {
return "id:" + id + "cat_id" + cat_id + "summary" + summary + "orig_date"
+ orig_item_date + "heding" + heding;
}
}
class body {
private String bpart;
public void setBpart(String r) {
this.bpart = r;
}
public String getBpart() {
return bpart;
}
#Override
public String toString() {
return "hiii";
}
}
}

The issue is in class Doll, You have a field ct but in json catitem. Rename the field ct to catitem or if you are using Gson use #SerializedName("catitem") on filed ct and it will work.

First, make sure you have the protocol set for your request.
Second, make sure that the String containing the URL is URL-encoded. I.e. the URL doesn't have any spaces and other special characters - these should be encoded (space is %20 etc).
Given that the two above are met, your program should not throw an exception from the java.net.URL class.
Looking at the exception above, you'll just have to set the protocol (http://), but do make sure that you encode your URL address strings properly or else you'll get exceptions from other parts of your program.
Also, adding http:// to the following string will also result in a MalformedURLException:
"localhost/uatpw/ActiveTransaction"?isx=E13F42EC5E38 as your URL would contain special characters (" in this case) which would need to be encoded.
To provide a valid URL you should make sure that the quotes are stripped from your URL's server and path segments areas:
localhost/uatpw/ActiveTransaction?isx=E13F42EC5E38. Prepeding http:// to this will result in a valid URL.

You are missing the protocol (e.g. http://) in front of localhost.
The welformed URL could be http://localhost/uatpw/ActiveTransaction

This is not a question. What are you trying to do?
But otherwise, "localhost/uatpw/ActiveTransaction" is not a valid URL. An url must start with a protocol (http, https, ftp, etc.).
You should try with:
http://localhost/uatpw/ActiveTransaction
