			HSSFSheet sheet = wb.getSheetAt(0);
			HSSFRow row;
			HSSFCell cell;

			Iterator rows = sheet.rowIterator();

			while (rows.hasNext()) {
				row = (HSSFRow) rows.next();
				
				for(int i=0; i<row.getLastCellNum(); i++) {
					cell = row.getCell(i, Row.CREATE_NULL_AS_BLANK);
					System.out.print(cell.toString()+" ");
				}
				System.out.println();
			}

		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	public static void main(String[] args) {
		readXLSFile();
		readXLSFileWithBlankCells();
	}

}

what if have to store data in key value pair and if there is unwanted blank space in the sheet.

Thank you so much for this, it really helped my out!

Thank you for your great solution.

The new way looks like this for newer versions of Apache POI API

XSSFWorkbook wb = new XSSFWorkbook(fis);
wb.setMissingCellPolicy(MissingCellPolicy.CREATE_NULL_AS_BLANK);

we need to set this attribute while creating object of XSSFWorkbook.

@sourabh09 absolute solution .
thanks
