In this tutorial, we are going to write a **Java program to find the sum and product of numbers** in **Java Programming** with practical **program code** and step-by-step full complete explanation.

## Java program to find sum and product of digits of the number.

class Sum_Product_ofDigit { public static void main(String args[]) { int num = Integer.parseInt(args[0]); //taking value as command line argument. int temp = num,result=0; //Logic for sum of digit while(temp>0) { result = result + temp; temp--; } System.out.println("Sum of Digit for "+num+" is : "+result); //Logic for product of digit temp = num; result = 1; while(temp > 0) { result = result * temp; temp--; } System.out.println("Product of Digit for "+num+" is : "+result); } }

### Output

7 Sum of Digit for 7 is : 28 Product of Digit for 7 is : 504
