I changed Scanner fin   new Scanner file   to Scanner fin   new Scanner new File file    and it works perfectly now  I didn t think the difference mattered but there you go

NumberFormatException invoke when you ll try to convert inavlid String for eg  abc  value to integer    this is  valid string is eg 123   in your case split by space    split       will split line by     by space
