Question

In Java, write a program using a loop that asks the user to enter a series of decimal numbers.

The user must enter -88 to end the input of the decimal numbers.

After the user enters all numbers, the program should display the sum of all numbers entered.

Answer 1

import java.util.Scanner;

public class SumDecimals {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        double total = 0, num;
        while (true) {
            System.out.print("Enter a number(-88 to stop): ");
            num = in.nextDouble();
            if (num == -88)
                break;
            total += num;
        }
        System.out.println("Sum of entered numbers is " + total);
    }
}
