YASH PAL, 31 July 2024

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 number

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
