Int array pushed through while loop until it reaches -1

I have to take a single line of user input, and calculate the average of all the numbers until it reaches -1 using a while loop. An example of user input could be something like 2 -1 6 which is why I’ve done it this way. I’ve figured out how to split this into an int array, but I can’t figure out how to do the while loop portion.

System.out.println("user input")
String user = scan.nextLine();
String[] string = user.split(" ");
int[] numbers = new int[string.length];
for(int i = 0;i < string.length;i++) {
    numbers[i] = Integer.parseInt(string[i]);
}
while ( > -1){
            
}

>Solution :

Class java.util.Scanner has methods hasNextInt and nextInt.

import java.util.Scanner;

public class Averages {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter series of integers on single line separated by spaces.");
        System.out.println("For example: 2 -1 6");
        int sum = 0;
        int count = 0;
        while (scan.hasNextInt()) {
            int num = scan.nextInt();
            if (num == -1) {
                break;
            }
            sum += num;
            count++;
        }
        double average = sum / (double) count;
        System.out.println("Average: " + average);
    }
}

Note that you need to cast count to a double when calculating the average otherwise integer division will be performed and that will not give the correct average.
