How do I read data from excel sheet and use data as an input for webpage using selenium ? I am able to read only 1 row at a time. Code displayed:

I have just started learning selenium and I am not able to automate the code only reads one at a time from excel.I need to make the code read from the excel automatically instead of changing the row count number in this line "for (int i= 1; i<=6; i++)."
How can I make it automatically read from the code below?
public static void main(String[] args) throws IOException, InterruptedException {
System.setProperty("driver location");
WebDriver driver = new FirefoxDriver();
driver.get("link");
FileInputStream file = new FileInputStream("xcel file location");
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet= workbook.getSheet("SO Reg");
int noOfRows = sheet.getLastRowNum(); // returns the row count
System.out.println("No. of Records in the Excel Sheet:" + noOfRows);
int cols=sheet.getRow(1).getLastCellNum();
System.out.println("No. of Records in the Excel Sheet:" + cols);
for (int i= 1; i<=6; i++)
{
String SO_Name = row.getCell(0).getStringCellValue();

Do you only want to process newly added rows in Excel? If so, you should also save your last stay.
First of all, you can simply keep it in an infinite loop. Like
while(true){...}
. You can also start your loop here by keeping the last line you read from Excel in a static variable.
For example:
for (int i= previusLastSavedRowNum; i<=getLastRowNum; i++) {...}
If there is no new record, you can wait for a while in the WHILE loop.
Of course, for a better solution, you can create a SpringBoot project and set up a structure that listens for changes in Excel. When Excel detects the change, you can call the Selenium code with a trigger.

Better way to handle it is to open the excel file as CSV.
You can read all the data into one String with:
String excelToString = new String(Files.readAllBytes(Paths.get(path_to_file)));
If you want to keep it as table you can parse this String into String [] [] table.

how can i get all the data in document firestore?

current i am working to my school project using android studio, it is an attendance system where I store my data to Firestore and the user are able to download/export the data to become Excel file. What I am trying to do is how can I get the all data in a single document of a Collection in firestore
here's the code but it is only getting the first data in a document and it is showing in all the rows
export.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
firebaseFirestore.collection("QR").document("QRScanned").collection(LoginProfessorTabFragment.superName)
.document(TeacherDash.subjectName1).collection("Record of Attendance")
.get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
#Override
public void onComplete(#NonNull Task<QuerySnapshot> task) {
if (task.isSuccessful()){
HSSFWorkbook hssfWorkbook = new HSSFWorkbook();
HSSFSheet hssfSheet = hssfWorkbook.createSheet(TeacherDash.subjectName1);
for (int i = 0; i < 4; i++) {//for creating equal amount of row from the database
HSSFRow row = hssfSheet.createRow(i);
for (int j = 0; j <= cellCount; j++) {//creating each cell depends on the cell counter
for (DocumentSnapshot documentSnapshot : task.getResult()){
String a = documentSnapshot.getString("Name");
String b = documentSnapshot.getString("Date");
String c = documentSnapshot.getString("Time");
String d = documentSnapshot.getString("StudentNumber");
String e = documentSnapshot.getString("Course");
String f = documentSnapshot.getString("Subject");
String g = documentSnapshot.getString("Room");
String h = documentSnapshot.getString("Schedule");
arrayExport.add(a);
arrayExport.add(b);
arrayExport.add(c);
arrayExport.add(d);
arrayExport.add(e);
arrayExport.add(f);
arrayExport.add(g);
arrayExport.add(h);
arrayRemoveAll.add(a);
arrayRemoveAll.add(b);
arrayRemoveAll.add(c);
arrayRemoveAll.add(d);
arrayRemoveAll.add(e);
arrayRemoveAll.add(f);
arrayRemoveAll.add(g);
arrayRemoveAll.add(h);
row.createCell(0).setCellValue(arrayExport.get(0));
row.createCell(1).setCellValue(arrayExport.get(1));
row.createCell(2).setCellValue(arrayExport.get(2));
row.createCell(3).setCellValue(arrayExport.get(3));
row.createCell(4).setCellValue(arrayExport.get(4));
row.createCell(5).setCellValue(arrayExport.get(5));
row.createCell(6).setCellValue(arrayExport.get(6));
row.createCell(7).setCellValue(arrayExport.get(7));
}
}
}
try {
if (!filePath.exists()) {
filePath.createNewFile();
Toast.makeText(TeacherDash.this, "Download success", Toast.LENGTH_SHORT).show();
}
FileOutputStream fileOutputStream = new FileOutputStream(filePath);
hssfWorkbook.write(fileOutputStream);
if (fileOutputStream != null) {
fileOutputStream.flush();
fileOutputStream.close();
}
} catch (Exception exception) {
exception.printStackTrace();
}
}
}
});
}
});

You are looping over things multiple times where you probably don't need to be. If you want to get multiple documents from a collection and have each document be a single row in the spreadsheet where the document fields fill the columns within that row, then you only need a single loop - over documents. It would look something like this:
HSSFWorkbook hssfWorkbook = new HSSFWorkbook();
HSSFSheet hssfSheet = hssfWorkbook.createSheet(TeacherDash.subjectName1);
int rowNum = 0;
for (DocumentSnapshot documentSnapshot : task.getResult()){
// Create a new row for each document
HSSFRow row = hssfSheet.createRow(rowNum);
++rowNum;
// Get the data from the firestore document
// you want to put in this row
String name = documentSnapshot.getString("Name");
String date = documentSnapshot.getString("Date");
String time = documentSnapshot.getString("Time");
String num = documentSnapshot.getString("StudentNumber");
String course = documentSnapshot.getString("Course");
String sub = documentSnapshot.getString("Subject");
String room = documentSnapshot.getString("Room");
String sched = documentSnapshot.getString("Schedule");
// Fill the contents of that row
row.createCell(0).setCellValue(name);
row.createCell(1).setCellValue(date);
row.createCell(2).setCellValue(time);
row.createCell(3).setCellValue(num);
row.createCell(4).setCellValue(course);
row.createCell(5).setCellValue(sub);
row.createCell(6).setCellValue(room);
row.createCell(7).setCellValue(sched);
}

Update: Can we filter the student document record by date range? Ex: get all the students data ONLY from 7-26-2022 upto 7-27-2022 (which will comes from a date range picker). We need to generate a report on where the student go from 7-26 to 7-27 by looking at the field room and time. It is basically a contact tracing feature. We also need to put it in an excel file.
I believe we can also use the code that we have above but with a few modifications. We are thinking on replacing our database structure from:
firebaseFirestore.collection("QR").document("QRScanned").collection(LoginProfessorTabFragment.superName).document(TeacherDash.subjectName1).collection("Record of Attendance")
and replace the last .collection("Record of Attendance) to .collection() so that we can have an organized data. Then starts to query by the date range?
Thank you for answering our question.

Java code to Search an Excel file with specific date and get the complete row which is matched

I am new to Java coding. I am trying to find a Java code to retrieve the specific rows from an Excel file when it matches with my date. I found some code on the Web but not able to successfully use it for searching the Excel and retrieving the rows.
For example, my Excel sheet contains below
Empno join_date first_name last_name dob
123456 02/24/2017 John Smiths 07/14/1990
324455 02/24/2017 David Conner 12/29/1991
388787 03/14/2017 Sam Brown 04/13/1991
I need to retrieve all rows which matched join_date as '02/24/2017' like below.
123456 02/24/2017 John Smiths 07/14/1990
324455 02/24/2017 David Conner 12/29/1991
Please help.

You need to use JXL Library and XLS format file.

Retrieve values from excel using poi

I am trying to get the column values for a specific row in a excel using poi methods.
I am able to get the values but the problem is I want the values only from second column.

wb = new HSSFWorkbook(fileInput);
sheet = wb.getSheet("Business Flow");
int rownr = findRow(sheet, Tcname);
row = sheet.getRow(rownr);
for (Cell cell : row) {
String arr = cell.getStringCellValue();
arrayListBusinessFlow.add(arr);
}
return arrayListBusinessFlow;
}
private static int findRow(HSSFSheet sheet, String cellContent){
for (Row row : sheet) {
for (Cell cell : row) {
if (cell.getCellType() == Cell.CELL_TYPE_STRING) {
if (cell.getRichStringCellValue().getString().trim().equals(cellContent)) {
return row.getRowNum();
}
}
}
}
return 0;

But I do not want my test case name when I am getting.
Please help me what changes i needed to do. thanks!

Currently, the code you're using to iterate over cells only returns cells with content or styling, and skips totally empty ones. You need to change to one of the other ways of iterating over cells, so you can control it to read from the second column onwards.
If you look at the Apache POI Documentation on iterating over rows and cells, you'll see a lot more details on the two main ways to iterate.
For your case, you'll want something like:
// We want to read from the 2nd column onwards, zero based
int firstColumn = 1;
// Always fetch at least 4 columns
int MY_MINIMUM_COLUMN_COUNT = 5;
// Work out the last column to go to
int lastColumn = Math.max(r.getLastCellNum(), MY_MINIMUM_COLUMN_COUNT);
// To format cells into strings
DataFormatter df = new DataFormatter();
// Iterate over the cells
for (int cn = firstColumn; cn < lastColumn; cn++) {
Cell c = r.getCell(cn, Row.RETURN_BLANK_AS_NULL);
if (c == null) {
// The spreadsheet is empty in this cell
} else {
// Do something useful with the cell's contents
// eg get the cells value as a string
String cellAsString = df.formatCellValue(c);
}
}

Use Cell cell=row.getCell(1); and also you can use sheet.getLastRowNum() to get the number last row on the sheet.
for (int i=0;i<=row.getLastCellNum();i++) {
if (i!=1){
//your stuff
}
}

what is the correct mapping in JAVA for a Varchar DB column which holds numeric values?

I have a column defined in a table in postgres DB as:
counterparty_company_number character varying(255)
I have written a JAVA code to populate this table with values from corresponding columns of an excel file. In the sample excel file, this column has 8 rows,out of which some are blank,like:
counterparty_company_number
blank
234567
345678
456789
567890
1.03E+09
blank
blank
In my model class,I have defined the attribute for this column as:
private String counterparty_company_number;
In my code, I replaced blank values with empty String while saving.After reading the data from excel and saving in DB,the values in corresponding column of DB table appear as:
""
"234567.0"
"345678.0"
"456789.0"
"567890.0"
"1.0304388E9"
""
""
This is the snippet from the code that reads the excel file and populates the table in DB:
..
//reads excel file and stores values in a list
FileInputStream file = new FileInputStream(new File(filepath));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet xssfSheet = workbook.getSheetAt(0);
if (xssfSheet.getLastRowNum() != 0) {
for (int i = 1; i <= xssfSheet.getLastRowNum(); i++) {
Row row = xssfSheet.getRow(i);
for (int j = 0; j < row.getLastCellNum(); j++) {
Cell cell = row.getCell(j);
if (cell != null) {
valueHolder.add(cell.toString());
} else {valueHolder.add("");
}
}
}
}
..
//sets attribute values in model class
if (!valueHolder.isEmpty() && valueHolder != null) {
for (int i = 0; i < valueHolder.size(); i += 10) {
CardsCounterparty ccp = new CardsCounterparty();
..
ccp.setCounterparty_company_number(valueHolder.get(i+3).toString());
..
counterpartyList.add(ccp);//counterpartyList is a list of counterparty objects
}
}
return counterpartyList;//this list is passed to the code that will save the objects in DB table
}
..
//code to persist in DB
Configuration c = new Configuration();
c.configure("/hibernate.cfg.xml");
SessionFactory sf = c.buildSessionFactory();
Session s = sf.openSession();
Transaction tx = s.beginTransaction();
try {
for (int i = 0; i < counterparties.size(); i++) {//counterparties is the list of all counterparty objects to be saved
CardsCounterparty ccp = counterparties.get(i);
s.save(ccp);
}
tx.commit();
s.close();
} catch (Exception e) {
tx.rollback();
}
}
I want to know how can I get the values in proper numeric format like 234567 instead of 234567.0 and 1030438800 instead of 1.0304388E9. I cannot change the datatype to int from String as the values may contain characters also and there may be blank values also.

Examine your SQL to ensure that the value that is getting inserted is surrounded by quotes to prevent any conversion from happening.
"update tablex set counterparty_company_number = '" + value + "'"
