Example:- Number = 12345 Then the odd digits in a given number are 1, 3, 5 and therefore sum of odd digits = 1 + 3 + 5 = 9 To get sum of each digits by c program, use the following algorithm: Step 1: Get number by user; Step 2: Get the modulus/remainder of the number; Step 3: sum the remainder of the number; Step 4: Divide the number by 10; Step 5: Repeat the step 2 while number is greater than 0. The following Java program computes the sum of digits of a number. For Example, Sum of digits of 2534 = 2 + 5 + 3 + 4 = 14 in Java Programs I needed to simply get the sum of a List of numbers and I found out there are a number of ways—pun intended—to do this. Display the output. Java program to calculate the sum of N numbers using arrays, recursion, static method, using while loop. But this approach requires a loop construct. ... Java Program to Calculate the Sum of Digits of Given Number How to swap two numbers using only two variables Checking the Given Number is Armstrong or Not Average an Array of Values Display ASCII Code Instead of Character Comparison of Two Variable using If Printing Table In java … The old fashion approach. If num=0 then it returns the sum value. Previously we have written a Java program to find the sum of digits of the given number. If the condition is False, then the compiler will return the Sum as Zero. Output : Sum of Digits = 15 So, now we create a java program to calculate the sum of digits of a given number. 1) Static method sum(long num), will calculate the sum of digits of a number. Here we will discuss the various methods to calculate the sum of the digits of any given number with the help of Java Programs. Call the static method sum(n) in the main method then the static method will be executed.
