        int markSum = 0;
        double average = 0;
        Scanner input1 = new Scanner(System.in);

        System.out.print("Enter student record : ");

        String name = input1.next();
        Scanner input2 = new Scanner(input1.nextLine());
        int countTotal = 0;

        while (input2.hasNextInt())
        {
            countTotal++;
            markSum += input2.nextInt();

        }

        average = markSum / countTotal;    // to calculate the total average
        System.out.print( name + "  " + average );
