Whenever 0 is entered in excel its read as 9 in the web

I have done a test case of data-driven testing, where 3 phone numbers and password will be read from excel and entered in the web.whenever I give a phone number ending with 0 in excel its typed as 9 during playback.
it can able to read rest of the phone numbers.follwing is the line of code to read data from excel.

double mobile = sheet1.getRow(j + 1).getCell(0 //Assuming that u have coulmn name in ur Excel sheet

    ).getNumericCellValue()



logger.info('mobile=' + mobile)



String mobilenum = String.valueOf(mobile)



WebUI.setText(findTestObject('Page\_ETV Win (3)/input\_mobile'), mobilenum)



String password = sheet1.getRow(j + 1).getCell(1 //Assuming that u have coulmn name in ur Excel sheet
