Java program to find SUM AND PRODUCT of a given Digit

Java program to find SUM AND PRODUCT of a given Digit :

 Class Sum_Product_ofDigit{

      public static void main(String args[]){

            int number = Integer.parseInt(args[0]);         //taking value as command line argument.

            int temp = number, result=0;

            //Sum of digit

            while(temp>0){

               result = result + temp;

               temp--;

            }

            System.out.println("Sum of Digit for "+number+" is : "+result);

            //product of digit

                        result = 1;

temp = number;

             while(temp > 0){

                 result = result * temp;

                 temp--;

            }

            System.out.println("Product of Digit for "+number+" is : "+result);

   }

}
