Solution
Sure, here is a simple Java program that reads an integer between 0 and 1000 and adds all the digits in the integer:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter an integer between 0 and 1000: ");
int num = input.nextInt();
int sum = 0;
while (num > 0) {
// Extract the least-significant digit
int digit = num % 10;
sum += digit;
// Remove the least-significant digit
num /= 10;
}
System.out.println("The sum of all digits is " + sum);
}
}
This program works by repeatedly extracting and removing the least-significant digit from the number until there are no more digits left. The extracted digits are then added together to compute the sum.

James, a mathematics teacher, is developing a programming exercise to help his students practice continuously summing the digits of a number until it becomes a single-digit integer. He wants to create a simple program using a 'while' loop that takes a positive integer input and generates the final single-digit result. Input format :The input consists of a positive integer n.Output format :The output prints "The single-digit sum of n is Y." where n is the input integer and Y is its single-digit sum.Refer to the sample output for formatting specifications.Code constraints :1 ≤ n ≤ 1010Sample test cases :Input 1 :456Output 1 :The single-digit sum of 456 is 6.Input 2 :999Output 2 :The single-digit sum of 999
Design an algoritm and write a Java program with a class that read an integer ‘n’ as input and print the ‘n’ natural numbers in descending order sequence and their “Sum”. Print ‘invalid’ if the boundary conditions are not met.Boundary Condition: 0 < n > 1000Input Format:The first line contains an integer ‘n’Output Format:The first ‘n’ line contains the natural numbers in descending sequence or invalidThe ‘n+1’th line contains the Sum
Design a program that mimics a digital calculator. Take an integer as input, use a function named sumOfDigits with a pointer to calculate the sum of its digits, and display the result. This simulates the process of manually adding up the individual digits of a number as you would on a calculator.Note: This question helps in clearing Wipro technical coding tests.Input format :The input consists of an integer N.Output format :The output prints an integer representing the sum of digits of N.Code constraints :1 ≤ N ≤ 105Sample test cases :Input 1 :123Output 1 :6Input 2 :5698Output 2 :28Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.Marks : 10Negative Marks : 0
