Question

Hello! I'd greatly appreciate it if someone could help me out with this problem.

"Complete the following program, which should allow the user to repeatedly enter input until a sentinel value of 0 is seen. Once input has finished, the program should show the average of the user's data, excluding the sentinel value itself. You may assume that the user will enter at least one non-sentinel value"

import java.util.Scanner;

public class SentinelValue {

public static void main(String [] args) {

}
}

Answer 1

import java.util.Scanner;

public class SentinelValue {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        double total = 0, count = 0, num;
        while (true) {
            num = in.nextDouble();
            if (num == 0) {
                break;
            }
            total += num;
            ++count;
        }
        System.out.println(total/count);
    }
}
