OpenCSV with Java spring boot can't read values of first column

I am trying to read values from csv file with Java spring boot with dependency of opencsv. But the values of first column are not geting readed while other columns are fine. It returns them as null.
Reader reader = Files.newBufferedReader(Paths.get(path));
CsvToBean<CsvBikeTrips> csvToBean = new CsvToBeanBuilder(reader)
.withType(CsvBikeTrips.class)
.withIgnoreLeadingWhiteSpace(false)
.build();
List<CsvBikeTrips> csvBikeTrips = csvToBean.parse();
public class CsvBikeTrips {
#CsvBindByName(column = "Departure")
private String departureTimestamp;
#CsvBindByName(column = "Return")
private String returnTimestamp;
#CsvBindByName(column = "Departure station id")
private String departureStationId;
#CsvBindByName(column = "Return station id")
private String returnStationId;
#CsvBindByName(column = "Departure station name")
private String departureStationName;
#CsvBindByName(column = "Return station name")
private String returnStationName;
#CsvBindByName(column = "Covered distance (m)")
private String coveredDistance;
#CsvBindByName(column = "Duration (sec.)")
private String duration;
public String getDepartureTimestamp() {
return departureTimestamp;
}
public void setDepartureTimestamp(String departureTimestamp) {
this.departureTimestamp = departureTimestamp;
}
public String getReturnTimestamp() {
return returnTimestamp;
}
public void setReturnTimestamp(String returnTimestamp) {
this.returnTimestamp = returnTimestamp;
}
public String getDepartureStationId() {
return departureStationId;
}
public void setDepartureStationId(String departureStationId) {
this.departureStationId = departureStationId;
}
public String getReturnStationId() {
return returnStationId;
}
public void setReturnStationId(String returnStationId) {
this.returnStationId = returnStationId;
}
public String getDepartureStationName() {
return departureStationName;
}
public void setDepartureStationName(String departureStationName) {
this.departureStationName = departureStationName;
}
public String getReturnStationName() {
return returnStationName;
}
public void setReturnStationName(String returnStationName) {
this.returnStationName = returnStationName;
}
public String getCoveredDistance() {
return coveredDistance;
}
public void setCoveredDistance(String coveredDistance) {
this.coveredDistance = coveredDistance;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
#Override
public String toString() {
return "CsvBikeTrips{" +
"departureTimestamp='" + departureTimestamp + '\'' +
", returnTimestamp='" + returnTimestamp + '\'' +
", departureStationId='" + departureStationId + '\'' +
", returnStationId='" + returnStationId + '\'' +
", departureStationName='" + departureStationName + '\'' +
", returnStationName='" + returnStationName + '\'' +
", coveredDistance='" + coveredDistance + '\'' +
", duration='" + duration + '\'' +
'}';
}
}
And the row of csv files look like this:
Departure,Return,Departure station id,Departure station name,Return station id,Return station name,Covered distance (m),Duration (sec.)

Ive tried something like this:
BufferedReader br = new BufferedReader(new InputStreamReader(
new FileInputStream(path), "UTF-8"));
And also to save the file in different txt editors but no success.

It happens that the file, in the beginning, had something like : ZWNBSP
Intelli J editor couldn't see that easily. It seems that it is related to BOM.
Unicode of that is \uFEFF
Fix:
InputStream input = new FileInputStream(path);
Reader reader = new InputStreamReader(new BOMInputStream(input), StandardCharsets.UTF_8);

I want to parse a Gson information but getting errors

I am trying to send the data of source and destination.
public void sendPost(final SearchSendModel searchSendModel){
//public void sendPost( String source, String destination){
Call call = mAPIService.sendSearch(searchSendModel);
//Call call = mAPIService.sendSearch(source, destination);
call.enqueue(new Callback<SearchModel>() {
#Override
public void onResponse(Call<SearchModel> call, Response<SearchModel> response) {
Toast.makeText(Search.this, " Responce " +response.body(), Toast.LENGTH_SHORT).show();
Log.v("Responce", "Responce "+response.body());
if (response.isSuccessful()){
SearchModel searchResponse = response.body();
assert searchResponse != null;
String content = "";
content += "Code: " +response.code() +"\n";
content += "vech_id: " + searchResponse.getVechId() +"\n";
content += "model_no: " + searchResponse.getModelNo() +"\n";
content += "reg_no: " +searchResponse.getRegNo() +"\n";
content += "delivery_start_date: " +searchResponse.getDeliveryStartDate() +"\n";
content += "delivery_end_date: " +searchResponse.getDeliveryEndDate() +"\n";
content += "full_percent: " +searchResponse.getFullPercent() +"\n";
content += "approval_status: " +searchResponse.getApprovalStatus() +"\n";
content +="source: " +searchResponse.getSource() +"\n";
content += "destination: " +searchResponse.getDestination() +"\n\n";
Toast.makeText(getApplicationContext(),content,Toast.LENGTH_LONG).show();
searchModelList.add(searchResponse);
}else {
Toast.makeText(getApplicationContext(),"Something is error",Toast.LENGTH_SHORT).show();
}
This is the Json response which i am expecting:
[
{
"vech_id": "30",
"model_no": "8956",
"reg_no": "98765",
"delivery_start_date": "2020-03-18",
"delivery_end_date": "2020-06-24",
"full_percent": "0.14",
"approval_status": "1",
"source": "ranchi",
"destination": "garwah"
}
]
Interface for API is:
#POST("search_vehicle.php")
#FormUrlEncoded
Call<SearchSendModel> sendSearch(#Body SearchSendModel searchSendModel);
SearchSendModel.java
public class SearchSendModel {
public SearchSendModel(String source, String destination) {
this.source = source;
this.destination = destination;
}
#SerializedName("source")
private String source;
#SerializedName("destination")
private String destination;
public String getSource() {
return source;
}
public String getDestination() {
return destination;
}
}
But I am getting this error always:
java.lang.IllegalStateException:Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 2 column 2 path$

I think your onResponse should use List<SearchModel> instead of SearchModel. Your response format is array.

});
The toast says that the data is successfully stored but in fact, it isn't. The toast also says that response.body() is null and there is no error in logcat even in the debugger. Please kindly help me. Thanks in advance for any help

I do not see where you are defining Hubungans, Agama and Jeniskelamin classes although you are using it as datatype inside your familylistresponsePOST.java
After creating these three classes, I hope your issue will be solved.

Here is what I did:

}
}
Here is some of my database code:
public List getAllComments() {
List customers = new ArrayList();
String inputText = "";
String query =

cursor.moveToFirst();
while (!cursor.isAfterLast()) {
Food customer = cursorToCustomer(cursor);
customers.add(customer);
cursor.moveToNext();
}
// make sure to close the cursor
cursor.close();
return customers;
}
private Food cursorToCustomer(Cursor cursor) {
Food customer = new Food();
customer.setCustomer(cursor.getString(0));

customer.setAddress2(cursor.getString(3));
customer.setCity(cursor.getString(4));
customer.setState(cursor.getString(5));

}
Here is Food.java:

}
public String getAddress1() {

}
public void setAddress1(String address1) {
this.address1 = address1;
}
public String getAddress2() {

}
public void setAddress2(String address2) {

}
public String getCity() {

}
public void setCity(String city) {

}
public void setState(String state) {

}
public String getZipCode() {
return zipCode;
}
public void setZipCode(String zipCode) {
this.zipCode = zipCode;
}
public String getCarb() {return carb;}
public void setCarb(String carb) {this.carb = carb;}
public String getFiber() {return fiber;}
public void setFiber() {this.fiber = fiber;}
public String getSugar() {return sugar;}
public void setSugar() {this.sugar = sugar;}
public String getProtein() {return protein;}
public void setProtein() {this.protein = protein;}
public String getSodium() {return sodium;}
public void setSodium() {this.sodium = sodium;}
}
So what did I do wrong here? Any help regarding this problem would be greatly appreciated.

mDbHelper.getAllComments() return List of Food class object's instead of String so response is not readable format. if you want to pass details from strlist to sender.sendMail then you will need to prepare another List which Store values from strlist as String. try is as:
ArrayList<Food> arrallcomments = mDbHelper.getAllComments();
List<String> strlist = new ArrayList<String>();
for(Food object: list){
strlist.add("Name : "+object.getName() +
" Customer :"+object.getCustomer()+...);
}
now use strlist for sending ArrayList with Mail.

Parse List of JSON objects using GSON

I have a JSON object like this:
{

"date": "06/26/2013",
"issues": [
{
"issueCode": "COC-2",
"comment": "\ncccccc",

}
],
"dayTotal": "20.533333333333335h"
}
]
},
"admin": {
"timeSpent": "601.1h",
"worklog": [
{
"date": "06/25/2013",
"issues": [

and trying to parse it with Gson:
Gson gson = new Gson();
Book responseBean = gson.fromJson(jsonString, Book.class);
But the 'responceBean' is always 'null'
Here are all the other classes:

}
public void setWorklogs(List<WorkLog> worklogs) {
this.worklogs = worklogs;
}
public String getTimeSpent() {
return timeSpent;

This is my latest attempt. Somehow I cannot figure out the right way. Will be very appreciative for any help.

Your JSON model does not match your object model.
You need an intermediate layer to fill the gap: a TypeAdapter.
Moreover there is no naming information for the user.
And finally there is a name mismatch: "worklog" in JSON, "worklogs" in Java.
Here is a fixed version:
Java model:
class User {
private String timeSpent;
#SerializedName("worklog")
private List<WorkLog> worklogs = new LinkedList<WorkLog>();
private String name;
public List<WorkLog> getWorklogs() {
return worklogs;
}
public void setWorklog(List<WorkLog> worklogs) {
this.worklogs = worklogs;
}
public String getTimeSpent() {
return timeSpent;
}
public void setTimeSpent(String timeSpent) {
this.timeSpent = timeSpent;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
The plumbing to fill the gap:
class BookTypeAdapter implements JsonSerializer<Book>, JsonDeserializer<Book>
{
Gson gson = new Gson();
public JsonElement serialize(Book book, Type typeOfT, JsonSerializationContext context)
{
JsonObject json = new JsonObject();
for (User user : book.getUser())
{
json.addProperty(user.getName(), gson.toJson(user));
}
return json;
}
public Book deserialize(JsonElement element, Type typeOfT, JsonDeserializationContext context) throws JsonParseException
{
JsonObject json = element.getAsJsonObject();
Book book = new Book();
for (Entry<String, JsonElement> entry : json.entrySet())
{
String name = entry.getKey();
User user = gson.fromJson(entry.getValue(), User.class);
user.setName(name);
book.getUser().add(user);
}
return book;
}
}
And a roundtrip:
GsonBuilder builder = new GsonBuilder();
builder.registerTypeAdapter(Book.class, new BookTypeAdapter());
Gson gson = builder.create();
Book book = gson.fromJson("{" +
" \"user1\": {" +
" \"timeSpent\": \"20.533333333333335h\"," +
" \"worklog\": [" +
" {" +
" \"date\": \"06/26/2013\"," +
" \"issues\": [" +
" {" +
" \"issueCode\": \"COC-2\"," +
" \"comment\": \"\ncccccc\"," +
" \"timeSpent\": \"20.533333333333335h\"" +
" }" +
" ]," +
" \"dayTotal\": \"20.533333333333335h\"" +
" }" +
" ]" +
" }," +
" \"admin\": {" +
" \"timeSpent\": \"601.1h\"," +
" \"worklog\": [" +
" {" +
" \"date\": \"06/25/2013\"," +
" \"issues\": [" +
" {" +
" \"issueCode\": \"COC-1\"," +
" \"comment\": \"\"," +
" \"timeSpent\": \"113.1h\"" +
" }" +
" ]," +
" \"dayTotal\": \"113.1h\"" +
" }," +
" {" +
" \"date\": \"06/26/2013\"," +
" \"issues\": [" +
" {" +
" \"issueCode\": \"COC-1\"," +
" \"comment\": \"\"," +
" \"timeSpent\": \"8h\"" +
" }," +
" {" +
" \"issueCode\": \"COC-2\"," +
" \"comment\": \"\"," +
" \"timeSpent\": \"480h\"" +
" }" +
" ]," +
" \"dayTotal\": \"488h\"" +
" }" +
" ]" +
" }" +
"}", Book.class);
String json = gson.toJson(book);
Have a look at my tutorial to get an idea of what is possible with Gson: Java/JSON mapping with Gson
Enjoy! :)

I had some problem before a month. As far as I remember it was because, same as you, I forgot to make "new" to objects. I mean that it should look:
public class User {
private String timeSpent;
private List<WorkLog> worklogs = new List < WorkLog >();
}
Try this and I hope that it will help.
P.S.
Also as Erik Pragt said you have array of Users, not just single one. So you will have to make 1 more class that contains a List < Users >.
