Processing: Uses recursion to add the last digit to the result of the recursive call, which processes the remaining digits. Output: The program prints the sum of the digits. Java Code Editor: Follow us onFacebookandTwitterfor latest update. ...
Arpit Mandliya In this post, we will see how to find sum of digits of number in java. You can find unit’s place digit by number%10, add it to the total and divide the number by 10 to remove the unit’s place. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ...
One of the common programming practice question thrown to beginners is to write a program to calculate the sum of digits in an integral number. For example, if the input is 123456 then output or sum of the digit is (1+2+3+4+5+6) = 21. An additional condition is you can not use ...
in); System.out.print("Enter A Number : "); num =sl.nextInt(); while(num >0) { r=num %10; sum=sum+r; num =num/10; } System.out.println("The Sum of Digit is : "+ sum); } }You’ll also like: Sum of Digits of a Number in Java Example C Program Sum of Digits of...
It then removes the last digit from 'n' by dividing it by 10 (n /= 10). This process continues until all digits of the original number have been processed. Finally, it returns the 'sum' containing the sum of the digits. Finally, back in the "main()" method, it prints the result...

Note that the value of digit will be modified in subsequent iterations. Thus, we should immediately add it to variable sum used to store the sum of digits. The variable sum should be initialized to zero before the loop. The program segment given below determines the sum of digits of the ...
