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() {

"detail='" + detail + '\'' +

}
}
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{" +

}
}
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{" +

Converting Paypal Checkout Transaction to a Java Object?

I've been working on a Paypal JSON to Java object converter, using Gson. But, it doesn't generate a full Java object. Seems like this conversion would have already been done, but I couldn't find anything.
My technique is to take the Paypal JSON, do replacements of their non-Java element names, then parse that into a Java object that I've defined.
Here's what the Gson looks like:
Gson gson = new GsonBuilder().serializeNulls().create();
JSONObjFromPaypalTrx jsonPaypalTrx = gson.fromJson(paypalTrx, JSONObjFromPaypalTrx.class);
logger.debug("jsonPaypalTrx: " +jsonPaypalTrx);
paypalTrx is the Paypal JSON after the element names are replaced:
paypalTrx: {"id":"PAYID-LXJIHMI92J52777N04488909","intent":"Sale","state":"approved","cart":"25M35194DL227451S","createTime":"2019-11-18T11:42:41Z","Payer":{"paymentMethod":"paypal","status":"VERIFIED","PayerInfo":{"email":"sb-cject591397#personal.example.com","firstName":"John","middleName":"John","lastName":"Doe","payerId":"5V25373K45VBE","countryCode":"US","ShippingAddress":{"recipientName":"John Doe","line1":"1 Main St","city":"San Jose","state":"CA","postalCode":"95131","countryCode":"US"}}},"Transactions":[{"Amount":{"total":"199.99","currency":"USD","Details":{"subtotal":"199.99","shipping":"0.00","handlingFee":"0.00","insurance":"0.00","shippingDiscount":"0.00"}},"ItemList":{},"RelatedResources":[{"Sale":{"id":"80E26736585579458","state":"completed","paymentMode":"INSTANT_TRANSFER","protectionEligibility":"ELIGIBLE","parentPayment":"PAYID-LXJIHMI92J52777N04488909","createTime":"2019-11-18T11:43:00Z","updateTime":"2019-11-18T11:43:00Z","Amount":{"total":"199.99","currency":"USD","Details":{"subtotal":"199.99","shipping":"0.00","handlingFee":"0.00","insurance":"0.00","shippingDiscount":"0.00"}}}}]}]}

Is the incomplete jsonPaypalTrx due to my use of inner classes inside JSONObjFromPaypalTrx? Splitting each inner class into separate Java files would be awkward for me to do.
Thanks for helping.

Given JSON payload uses mixed naming convention: camel case and UPPER_CAMEL_CASE for JSON Objects. So, you need to implement your own FieldNamingStrategy:
class PayPalFieldNamingStrategy implements FieldNamingStrategy {
#Override
public String translateName(Field f) {
return f.getType() == String.class ? f.getName() : FieldNamingPolicy.UPPER_CAMEL_CASE.translateName(f);
}
}
And register it like below:
Gson gson = new GsonBuilder()
.setFieldNamingStrategy(new PayPalFieldNamingStrategy())
.create();
Or, for each object declare name like below:
#SerializedName("Payer")
private Payer payer;

Make your member classes static so that they don't need an outer class reference when they're constructed.
Like: public static class ShippingAddress.
Gson likely doesn't know how to constructor inner classes, but it will know how to construct static member classes.

How to parse symbol ":" in Json String

I want to parse json string into JSONObject but the symbol ":" seems to parse the error
For example -> "time": "2019-05-28T16:30:29Z" will be wrong
But changed to "time": "20190526" is OK
This is the entire json object:
{
"channel": 922875000,
"sf": 12,
"time": "2019-05-28T16:30:29Z",
"gwip": "192.168.0.180",
"gwid": "00001c497b431ff5",
"repeater": "00000000ffffffff",
"systype": 170,
"rssi": -103,
"snr": 20.5,
"snr_max": 33,
"snr_min": 18,
"macAddr": "00000000aabb60ba",
"data": "00000000",
"frameCnt": 8,
"fport": 3
}
and the parse code:
try {
JSONObject sensorObject = new JSONObject(message.toString());
SensorModel sensorModel = new Gson().fromJson(sensorObject.toString(), SensorModel.class);
} catch (JSONException e) {
logger.error(e.getMessage());
}
How can I let him keep the same "2019:05:26" content?

Getting "The request sent by the client was syntactically incorrect" when parsing the following JSON using Spring REST and Jackson

Using Spring 4 and Jackson 1.9.13, when making the rest call I am getting an error back saying "The request sent by the client was syntactically incorrect" and the call doesn't enter the REST method...
JSON is this array of arrays format:
[ "location",
[
{
"regions":[],
"x":10.0,
"y":14.0,
"timeExpires":1387219731911,
"confidence":0.9,
"timestamp":1387219671911,
"source":"wifi",
"associated":true,
"clientMac":"1c:4f:2b:14:c9:8b",
"clientType":"AbC Device",
"adspNetworkPath":"/a/b/c1",
"folderID":10007,
"floorNumber":1,
"timeComputed":1387219671911
},
{
"regions":[],
"x":8.222222,
"y":18.88889,
"timeExpires":1387219726912,
"confidence":0.9,
"timestamp":1387219666912,
"source":"wifi",
"associated":true,
"clientMac":"64:a3:ab:6b:5d:4f",
"clientType":"123 Device",
"adspNetworkPath":"/a/b/d1",
"folderID":10007,
"floorNumber":1,
"timeComputed":1387219666912
}
]
]
the Spring Controller looks like:
#RequestMapping(value="/location", method=RequestMethod.POST)
public #ResponseBody void locationData(#RequestBody List<Location> locationList) {
logger.info("Inside locationData() method...");
ObjectMapper mapper = new ObjectMapper();
try {
// just convert to list of object and display back for now...
String jsonString = mapper.writeValueAsString(locationList);
logger.info(jsonString);
} catch (IOException e) {
e.printStackTrace();
}
}
the Model object is where I am having the problem.

It should be something like this.
