Feb 10, 2023 · Given a list of numbers, write a Java program to find the sum of all the elements in the List using for loop. For performing the given task, complete List traversal is necessary which makes the Time Complexity of the complete program to O(n), where n is the length of the List. Example: Input : List

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.

Nov 24, 2014 · In Java 8, public int sum(int number) { return (number + "").chars() .map(digit -> digit % 48) .sum(); } Converts the number to a string and then each character is mapped to it's digit value by subtracting ascii value of '0' (48) and added to the final sum.

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.
