Answer 1

import java.util.Scanner;

class Test

{

public static void main(String[] args)

{

Scanner input=new Scanner(System.in);

System.out.println("Enter 3 digit number:");

int n= input.nextInt();

int sum=0;

while (n != 0)

{

sum = sum + n % 10;

n = n/10;

}

System.out.println("Sum :"+sum);

}

}

Input :Enter 3 digit number:123

Output :Sum :6

Answer 2

import java.util.*;

public class Sum

{

public static  void main(String args[])

{

Scanner in=new Scanner(System.in);

//for taking input decimal numbers we have to accept the values either in float or in double.

//taking the input in float

float m,n,k, sum;

System.out.println("Enter the values");

m= in.nextFloat();

n=in.nextFloat();

k=in.nextFloat();

sum=(m+n+k);

System.out.println("The sum of the decimals is=" +sum);

}

}
