Iterator rowsExcel = sheet.rowIterator();

XSSFRow row2 = null;
if (uygunluk == true) {
    while (rowsExcel.hasNext()) {

        row2 = (XSSFRow) rowsExcel.next();
        if (row2.getRowNum() != 0) {
             if (fmt.formatCellValue(row2.getCell(0)) == null || (fmt.formatCellValue(row2.getCell(0)).trim().equalsIgnoreCase(""))) {
               System.out.print.ln("warn!!");
                return;
            } else if (fmt.formatCellValue(row2.getCell(0)) != null || !(fmt.formatCellValue(row2.getCell(0)).trim().equalsIgnoreCase(""))) {
                idInfo = fmt.formatCellValue(row2.getCell(0);
            }
