Question

Complete the following code snippet using java so that it finds the sum of doubles the user inputs. Your answer should be a while loop with a condition that needs to be true if the user inputs a double. Your answer should be a single while loop.

Scanner scnr = new Scanner(System.in);

int sum = 0;

Answer 1

ANSWER: Here below is the code where I am taking input as a double so when input a string input the while will break and print the sum and since you need to sum of the double values so sum should be double type not int. Please like it or comment your problem before going to downvote.

CODE:

import java.util.Scanner;

public class Demo {

   public static void main(String[] args) {
       Scanner scnr = new Scanner(System.in);

       double sum = 0;
           while(scnr.hasNextDouble()) {//here I am checking that user input is double or not.
               double in=scnr.nextDouble();// taking input
               sum+=in;//adding into sum.
           }
          
           System.out.println("Sum:"+sum);//displaying sum
   }

}

OUTPUT:
