Thread: Writing in the column excel

public void scriviNewId() throws IOException {
		String FILE_NAME = "C:\\Users\\java\\Desktop\\x.xlsx";
		InputStream inp = new FileInputStream(FILE_NAME);
		Workbook wb = WorkbookFactory.create(inp);
		Sheet sheet = wb.getSheetAt(0);
 
		//Vai a leggere la nuova colonna
		Cliente cliente = new Cliente();
		cliente.fillVeicoloId();
 
		for (int i = 0; i < cliente.getVeicoloId().size(); i++) {
			Row row = sheet.createRow(i + 1); //Inizia alla riga 1
			System.out.println("Scrivi:  " + cliente.getVeicoloId().get(i));
 
			// Specific cell number 
	        Cell cell = row.createCell(5); 
 
	        // putting value at specific position 
	        cell.setCellValue(cliente.getVeicoloId().get(i)); 
 
			//row.createCell(5).setCellValue(cliente.getVeicoloId().get(i)); // Colonna 34
 
		}
 
		FileOutputStream fileOut = new FileOutputStream(FILE_NAME);
		wb.write(fileOut);
		fileOut.close();
 
	}

Why does it overwrite other columns?

In practice, I like to write this code in column F.
But when he writes in column F, he deletes the data from the other columns, how come?

column

A B C D E F
0
1
5
..


the other columns delete them and I do not want the data of the other columns to be deleted

yes the column is completely filled in, how can I solve the problem?
