Question

Script 1: Sum of Numbers Write a python program that asks the user to enter a series of single-digit numbers with nothing separating them. The program should display the sum of all the single digit numbers in the string. For example, if the user enters 2514, the method should return 12, which is the sum of 2, 5, 1, and 4.

Answer 1

Program:

import java.util.Scanner;
public class SumofDigits { // Here taking the class name as SumofDigits
public static int SumofDigits(int num) // Definition of SumofDigits() method
{
int n=0,sum=0; // Here Initializing integer varaibles called n,sum
while(num!=0)
{ // Loop Iteration
n=num%10; // Here calculating n value
sum+=n; // Here adding n value to sum
num=num/10; // Here dividing num with 10
} // End of while loop
return sum; // Here Sum is Returned to main()
} // End of SumofDigits() method
public static void main(String args[]) { //Start of main()
int Num;// Here declaring integer varaible called NUm
Scanner in = new Scanner(System.in);
System.out.println("Enter Series of single-digit numbers: ");
Num = in.nextInt(); // HEre scanning User input
SumofDigits ob=new SumofDigits(); // Here creating Object called ob for class SumofDigits
System.out.println("The sum is "+ob.SumofDigits(Num)); // Here calling SumofDigits() method using object ob
} // End of main()
}// End of class SumofDigits

Output:
