Answer 1

Answer:

import java.util.Scanner;

public class abc

{

public static void main (String args[ ])

{

Scanner scan=new Scanner (System.in);

System.out println("Enter number");

int n=scan.nextInt();

itn sum=0;

while(n!=0)

{

int d= n%10;

if (d%2==0)

sum+=d;

n=n/10;

}

System.out.println(sum);

Explanation:

(Line 1) Importing scanner class for input

(Line 2 and 3) Creating class

Line 4) Creating object of scanner class

(line 5) Inputting number by user

(line 6) delcaring a variable to allow the program to store the value of no. in it

(line 7) defining sum variable with 0 before hand to avoid further errors

(line 8) starting with while loop with the testing condition for extracting the digits of the no.

(line 9) extracting digits in the variable d

(line 10) checking if the digit is even

(line 11) if it is even adding it to sum variable

(line 12) update condition of the loop

(line 13) out of the loop, printing the sum value.
