Printing out results in a map loading contents from a xlsx file using POI

so I need to print out the product id and image url from a excel file as I need to modify another file with the contents I retrieve, however for some reason the mappings is empty, but if I print the values out directly it shows them correctly.
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.*;
public class Main {
static final Map<String, String> PRODUCT_CODES_BY_IMAGES = new HashMap<>();
public static void main(String[] args) throws IOException, InvalidFormatException {
File file = new File("./data/stock_met_imageurls.xlsx");
FileInputStream fis = new FileInputStream(file);
Workbook workbook = new XSSFWorkbook(fis);
Sheet datatypeSheet = workbook.getSheetAt(0);
Iterator<Row> iterator = datatypeSheet.iterator();
while (iterator.hasNext()) {
Row currentRow = iterator.next();
Iterator<Cell> cellIterator = currentRow.iterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
if(cell != null && cell.getCellTypeEnum().equals(CellType.STRING)) {
String image_url = null;
String product_id = null;
switch(cell.getColumnIndex()) {
case 0:
image_url = cell.getStringCellValue();
break;
case 2:
product_id = cell.getStringCellValue();
break;
}
if(image_url != null && product_id != null) {
PRODUCT_CODES_BY_IMAGES.put(product_id, image_url);
}
}
}
}
PRODUCT_CODES_BY_IMAGES.forEach((k, v) -> {
System.out.println("key = " + k);
System.out.println("val = " + v);
});
System.out.println("Size = " + PRODUCT_CODES_BY_IMAGES.size());
}
}
if I did under the cases
System.out.println("val = " + cell.getStringCellValue());
it prints it out correctly but for some reason the mappings is empty?
Any help would be greatly appreciated.

Because your map is declared as static final. Check out https://www.baeldung.com/java-final

Fixed, I added the elements in the mappings above the wrong bracket.

How to edit excel file with large data using SXSSF change cell color

I have read all previous ask question but there is solution I found.
How to Edit existing large excel file with SXSSF Streaming api
How to write to an existing file using SXSSF?
I have a existing file which I required to update the content change cell color for some content.
I need to modify excel file with large data over 40,000 rows.
Steps done in below code.
Create new file for Result, Copy file 2 for result to highlight not
equal cell
Create Workbook for 2 compare excel files Temp
XSSFWorkbook XSSF cellStyleRed as SXSSFWorkbook cannot have cellstyle color
keep 100 rows in memory, exceeding rows will be flushed to disk
compareTwoRows from both excel file not equal will change cellstyle color to red on Result file.
Problem is with below code Result file is blank there is no content. I understand my code
is incorrect as SXSSFWorkbook is creating new sheet.
HOW CAN I update result file by change cell color?

in general 40'000 rows is a very small volume of data and I would not
like to suggest employing Streaming in that case.
Instead, you can hold 40'000 rows in a XSSF workbook easily if you just
provide enough memory. Using a XSSF workbook, you can modify the
content directly as you have tried.
However, if you work with really large data of 1 Mill. rows and many
columns, then the following approach will help:
1) engange the Excel Streaming Reader
2) read both files F1 and F2 simultaneously and compare row by row and
cell by cell
3) based on the found difference, create a new row with new cells and
write that to your result file F3
You can not modify existing cells in a SXSSFWorkbook.

For-loop prints only the last value of Array through whole Excel file

I am struggling through this IBAN Checker JAVA project where I am supposed to take IBANs from an excel sheet -> validate them -> print valid/invalid results back into Excel. I have it almost all set up but now I got stuck on looping function that should put already validated IBANS back to the sheet. Here I am getting only last IBAN number of my IBAN Array which gets printed into all the rows, other IBANs are not showing.
However, when I use "System.out.printf("%s is %s.%n", iban, validateIBAN(iban) ? "valid" : "not valid");" function all the ibans are validated correctly and printed into console one by one.
Is there please some way to get the results of above "System.out.printf" and iterate them through the cells in the Excel sheet? Or would you have some suggestion for modifications of the for-loop please? I think something in the loop is causing the issue because when I put "System.out.prinf" function inside of the loop, it starts validating only the last IBAN number which means something with the loop is not right.
Thank you very much for any help you can give!

state the create table name in jdbc without .xls

i made a program in java that it takes an excel file and store its data in a database. When i state where the file is its like this:
String filename = "test5.xls";
String path = "C:\\Users\\myfiles\\Documents\\";
But when i call the create table and i state the filename of the excel file because it it test.xls the mysql command shows error!
The create table function is:
try
{
String all = org.apache.commons.lang3.StringUtils.join(allFields, ",");
String createTableStr = "CREATE TABLE " + "table5" + " (" + all + ")";
System.out.println( "Create a new table in the database" );
stmt.executeUpdate( createTableStr );
Is there any way to rename the file before i create the table or to read only the "test" without the .xls?

Thank you in advance!

Gives name of the file
String filename = "test5.xls";
String path = "C:\\Users\\myfiles\\Documents\\";
File f = new File (path + filename);
System.out.println(f.getName());// gives only file name with out extension
