Answer:
import java.util.Scanner;
public class num10 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the numbers to add up. enter 999 to stop");
int num = in.nextInt();
int sum = 0;
while (num!=999){
sum = sum+num;
System.out.println("Enter the next number");
num = in.nextInt();
}
System.out.println("The sum is: "+sum);
}
}
Explanation:
The application is implemented in Java
A while loop is used to continously prompt user for inputs. The condition of the while loop is while (num!=999)
When the number 999 is entered, it displays the sum which is initialized to 0
