Why doesn't my “While Loop” print the computation of finding the average “score”?

Question

I am writing a program that reads a sequence of positive integers input by the user. User will only enter one integer at a time.Then it will compute the average of those integer

Answer 1

You need to move integer = input.nextInt(); inside the loop, so your program will collect inputs in a loop. See the corrected version:

import java.util.Scanner;

public class AverageOfIntegers {

    public static void main(String[] args) {

        int integer = 0, count = 0; 
        double sum = 0.0, average = 0.0; 
        Scanner input = new Scanner(System.in);

        System.out.println("Please enter an integer: ");
        integer = input.nextInt();

        while (integer != 0) {
            count = count + 1;  
            sum = sum + integer; 
            System.out.println("Please enter an integer: ");
            integer = input.nextInt();
        }

        average = sum / count;
        System.out.println("Average = " + average);
    }
}
