List SheetData = new ArrayList();

InputStream fs = new FileInputStream(filename);

XSSFWorkbook wb = new XSSFWorkbook(fs);

XSSFSheet sheet = wb.getSheetAt(0);

try

Header header = sheet.getHeader();
int rowsCount = sheet.getLastRowNum();

System.out.println("Total Number of Rows: " + (rowsCount + 1));
