Code that is to read a line 10 two columns of data, a line dividing a line dividend, and then output a new file including the divisor four columns, dividend, quotient and remainder, when the input file does not exist, the dividend is 0, the input for the decimal when all can run, FileNotFoundException ArithmeticException emerged and there is no problem, but when appear InputMismatchException output file is empty, Java small white, hope the great god help to look at, very grateful!
All the code below,
