POI: Read from specific line and send to BD

Question

Hello. I am working on a TCC in JAVA and one of its functions will be reading EXCEL files and sending the data to the Database.

I’m starting little by little in JAVA and some things still confuse a lot, which is why I’ve been doing a lot of research on this. The question is: As I do from the example below, I can start reading from line 5 of . xlsx and how to export this data to the Database?

I’m 3 days researching and since I found nothing specific, I’m resorting to Stackoverflow... Thanks from now on

public static void main(String[] args) {

    FileInputStream fisPlanilha = null;

    try {
        File file = new File("C:\\Users\\wi-li\\Downloads\\PrograminhasLerXlsx\\xlsx\\planilhas\\planilhaDaAula.xlsx");
        fisPlanilha = new FileInputStream(file);

        //cria um workbook = planilha toda com todas as abas
        XSSFWorkbook workbook = new XSSFWorkbook(fisPlanilha);

        //recuperamos apenas a primeira aba ou primeira planilha
        XSSFSheet sheet = workbook.getSheetAt(0);

        //retorna todas as linhas da planilha 0 (aba 1)
        Iterator<Row> rowIterator = sheet.iterator();

        //varre todas as linhas da planilha 0
        while (rowIterator.hasNext()) {

            //recebe cada linha da planilha
            Row row = rowIterator.next();

            //pegamos todas as celulas desta linha
            Iterator<Cell> cellIterator = row.iterator();

            //varremos todas as celulas da linha atual
            while (cellIterator.hasNext()) {

                //criamos uma celula
                Cell cell = cellIterator.next();

                switch (cell.getCellType()) {

                    case Cell.CELL_TYPE_STRING:
                        System.out.println("TIPO STRING: " + cell.getStringCellValue());
                        break;

                    case Cell.CELL_TYPE_NUMERIC:
                        System.out.println("TIPO NUMERICO: " + cell.getNumericCellValue());
                        break;

                    case Cell.CELL_TYPE_FORMULA:
                        System.out.println("TIPO FORMULA: " + cell.getCellFormula());
                }

            }
        }

    } catch (FileNotFoundException ex) {
        Logger.getLogger(LendoXLSX.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(LendoXLSX.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        try {
            fisPlanilha.close();
        } catch (IOException ex) {
            Logger.getLogger(LendoXLSX.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
