Feb 10, 2023 · Given a number, find the sum of its digits. 1. Iterative: How to compute in single line? 2. Recursive. Please refer complete article on Program for Sum the digits of a given number for more details!

Feb 7, 2025 · Given a number n, find the sum of its digits. Examples : The idea is to add the digits starting from the rightmost (least significant) digit and moving towards the leftmost (most significant) digit.

Nov 24, 2014 · public static int sumOfDigits(int n) { String digits = new Integer(n).toString(); int sum = 0; for (char c: digits.toCharArray()) sum += c - '0'; return sum; } You can use it like this: System.out.printf("Sum of digits = %d%n", sumOfDigits(321));

In order to find the sum of digits of a number, we must familiar with the Java loops and operators. Enter any integer number as input. After that, we use modulus and division operation respectively to find the sum of digits of the number as output. Let's see the steps. Declare a variable (sum) to store the sum of numbers and initialize it to 0.

Calculating the sum of all digits in a number is a basic programming task that demonstrates the use of arithmetic operations and control structures. In this blog post, we will use Java 8 features to streamline the process of adding up the digits of a given number.

Learn how to write a Java program to calculate the sum of digits in a given number. This guide includes logic explanation and sample code.

In this article we will show you, how to Write a Program to Find Sum of Digits in Java using For Loop, While Loop, Functions and Recursion.

Jul 30, 2024 · Finding the sum of the digits of a number is a fundamental exercise that helps in understanding loops and arithmetic operations in programming. This Java program demonstrates how to calculate the sum of the digits by extracting each digit and summing them up.

Oct 5, 2024 · Learn how to calculate the sum of digits of a number in Java using two approaches: a while loop and recursion. Step-by-step explanation and code examples provided.

May 24, 2023 · Here, we will discuss three different approaches to calculate the sum of digits of a Number in Java. Approach 1: Sum of Digits of a Number in Java By using for loop. The sumOfDigits is increased by the remaining n/10 after the for loop iterates until n!=0 is false. The for loop is broken and the sum is reported if n=0. Code Implementation
