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);

Im working on a project where I have 3 text files with data of doctors, patients and home visits. When Im trying to upload the doctors file, upload all the data to a new object I get an error:

Because of the data spacing in the file, try this:
while(readerLekarze.hasNextLine()){
String line = readerLekarze.nextLine();
// Remove leading and trailing whitespaces (if any).
line = line.trim()
// "\\s+" Takes care of any multi-spacing within the data line when splitting.
String[] data =line.split("\\s+");
lekarz.add(new Lekarz(Integer.parseInt(data[0]),data[1],data[2],data[3],new SimpleDateFormat("yyyy-MM-dd").parse(data[4]),data[5],data[6]));
}
You could also just do:
String[] data = readerLekarze.nextLine().trim().split("\\s+");
As a complement to the #DevilsHnd, you only need to add a code to avoid the first line, because the first line is the "header information" of your file.
boolean headerRead = false;
while(readerLekarze.hasNextLine()) {
if (!headerRead) {
// extract the first line -> Id_pacjenta Nazwisko Imie PESEL Data_urodzenia
readerLekarze.nextLine();
headerRead = true;
continue;
}
String line = readerLekarze.nextLine();
// Remove leading and trailing whitespaces (if any).
line = line.trim();
// "\\s+" Takes care of any multi-spacing within the data line when splitting.
String[] data =line.split("\\s+");
lekarz.add(new Lekarz(
Integer.parseInt(data[0]),
data[1],
data[2],
data[3],
new SimpleDateFormat("yyyy-MM-dd").parse(data[4])));
}

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.
My code is 100% working. I dont understand when i store the receiving output from Volley onresponse, i cant seem to store them correctly into my object. The raw output is correct. When i store it into my object, and then try to read the object, it showing wrong information.
For example, there is no data for contact and data for position is output at wrong place.
Log.d("TAG", "onResponse : "+ response.toString());
myProfile.set_firstname(response.optString("firstname", ""));
myProfile.set_lastname(response.optString("lastname", ""));
myProfile.set_contact(response.optString("contact", ""));
myProfile.set_email(response.optString("email", ""));
myProfile.set_position(response.optString("position", ""));
myProfile.set_areaname(response.optString("area", ""));
myProfile.set_deptname(response.optString("department", ""));
Log.d("TAG", "myProfile SET : " +
"firstname: "+myProfile.get_firstname() + " " +
"lastname: "+myProfile.get_lastname() + " " +
"contact: "+myProfile.get_contact() + " " +
"email: "+myProfile.get_email() + " " +
"position: "+myProfile.get_position() + " " +
"area: "+myProfile.get_areaname() + " " +
"dept: "+myProfile.get_deptname()
);
Raw JSON response from Volley and Log.d
onResponse : {"firstname":"kirpal","lastname":"SINGH","contact":"0164028083","email":"kirpal#gmail.com","position":"Technician","area":"Nextrack","department":"nexpro"}
myProfile SET : firstname: kirpal lastname: SINGH contact: Technician email: kirpal#gmail.com position: area: Nextrack dept: nexpro
MyProfile.java
public class MyProfile {
private String id="";
private String firstname="";
private String lastname="";
private String areaname ="";
private String deptname ="";
private String contact ="";
private String email ="";
private String position ="";
//SET
public void set_id(String id){this.id = id;}
public void set_firstname(String firstname){this.firstname = firstname;}
public void set_lastname(String lastname){this.lastname = lastname;}
public void set_areaname(String areaname){this.areaname = areaname;}
public void set_deptname(String deptname){this.deptname = deptname;}
public void set_contact(String contact){this.contact = contact;}
public void set_email(String email){this.email = email;}
public void set_position(String position){this.contact = position;}
//GET
public String get_id(){return this.id;}
public String get_firstname(){return this.firstname;}
public String get_lastname(){return this.lastname;}
public String get_areaname(){return this.areaname;}
public String get_deptname(){return this.deptname;}
public String get_contact(){return this.contact;}
public String get_email(){return this.email;}
public String get_position(){return this.position;}
}
Wrong info shows because you set position on contact and also set position on position.
public void set_position(String position){this.contact = position;}
change to
public void set_position(String position){this.position = position;}
I need to parse the below JSON content. Currently I have stored it inflat file and reading it. I have given the sample POJO classes which are created and the code which I tried below.
Tried two different approach and both are giving the following error

Aproach2:
Gson gson = new Gson();
DeviceList [] myTypes = gson.fromJson(new FileReader("/home/raj/apache-tomcat-8.0.3/webapps/file.json"), DeviceList[].class);

I have encountered a problem in my Android application. The problem is that when I try to retrieve data from my database, I get code that I cannot read. I am an amateur programmer and don't know too much about Android programming. Here is my output:

Here is what I did:
public void send (View v) {
List<String> strlist = new ArrayList<String>();
strlist = mDbHelper.getAllComments();
GmailSender sender = new GmailSender("omitted", "omitted");
try {
sender.sendMail("DietWatcher Feedback",
strlist + "",
"ommited",
"omitted");
Toast.makeText(getApplicationContext(), "Sent!", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Cannot send message!", Toast.LENGTH_SHORT).show();
}
}
Here is some of my database code:
public List getAllComments() {
List customers = new ArrayList();
String inputText = "";
String query =
KEY_CUSTOMER + /*"INTEGER," + */ "," +
KEY_NAME + "," +
KEY_ADDRESS1 + "," +
KEY_ADDRESS2 + "," +
KEY_CITY + "," +
KEY_STATE + "," +
KEY_ZIP + "," +
KEY_SEARCH + "," +
TOTAL_CARB + "," +
FIBER +
SUGAR +
PROTEIN+
SODIUM +
TOTALCALORIES +
FTS_VIRTUAL_TABLE +
KEY_SEARCH;
Log.w(TAG, query);
//Cursor mCursor = mDb.rawQuery(query,null);
Cursor cursor = mDb.query(FTS_VIRTUAL_TABLE, new String[]{KEY_CUSTOMER + "," +
KEY_NAME + "," +
KEY_ADDRESS1 + "," +
KEY_ADDRESS2 + "," +
KEY_CITY + "," +
KEY_STATE + "," +
KEY_ZIP + "," +
TOTAL_CARB /*+
FIBER +
SUGAR +
PROTEIN+
SODIUM +
TOTALCALORIES +
FTS_VIRTUAL_TABLE +
KEY_SEARCH */}, null, null, null, null, null);
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.setName(cursor.getString(1));
customer.setAddress1(cursor.getString(2));
customer.setAddress2(cursor.getString(3));
customer.setCity(cursor.getString(4));
customer.setState(cursor.getString(5));
customer.setZipCode(cursor.getString(6));
return customer;
}
Here is Food.java:
package com.example.foodsaver2;
public class Food {
String customer = null;
String name = null;
String address1 = null;
String address2 = null;
String city = null;
String state = null;
String zipCode = null;
String carb = null;
String fiber = null;
String sugar = null;
String protein = null;
String sodium = null;
public String getCustomer() {
return customer;
}
public void setCustomer(String customer) {
this.customer = customer;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress1() {
return address1;
}
public void setAddress1(String address1) {
this.address1 = address1;
}
public String getAddress2() {
return address2;
}
public void setAddress2(String address2) {
this.address2 = address2;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = 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.
