Apache POI XSSF reading in excel files

Question

I just have a quick question about how to read in an xlsx file using the XSSF format from Apache.

Right now my code looks like this:

InputStream fs = ne

You can try the following.

private static void readXLSX(String path) throws IOException {
    File myFile = new File(path);
    FileInputStream fis = new FileInputStream(myFile);

    // Finds the workbook instance for XLSX file
    XSSFWorkbook myWorkBook = new XSSFWorkbook (fis);

    // Return first sheet from the XLSX workbook
    XSSFSheet mySheet = myWorkBook.getSheetAt(0);

    // Get iterator to all the rows in current sheet
    Iterator rowIterator = mySheet.iterator();

    // Traversing over each row of XLSX file
    while (rowIterator.hasNext()) {
        Row row = rowIterator.next();

        // For each row, iterate through each columns
        Iterator cellIterator = row.cellIterator();
        while (cellIterator.hasNext()) {

            Cell cell = cellIterator.next();

            switch (cell.getCellType()) {
            case Cell.CELL_TYPE_STRING:
                System.out.print(cell.getStringCellValue() + "\t");
                break;
            case Cell.CELL_TYPE_NUMERIC:
                System.out.print(cell.getNumericCellValue() + "\t");
                break;
            case Cell.CELL_TYPE_BOOLEAN:
                System.out.print(cell.getBooleanCellValue() + "\t");
                break;
            default :

            }
        }
        System.out.println("");
    }
}
