Design and implement a program that reads a series of 10 integers from the user and prints their average. Read each input value
irina [24]

Answer:

Explanation:

The following program was written in Java. It creates a loop that asks the user for numbers. If it can convert it to an integer it accepts it and adds it to the sum variable otherwise it ouputs that it is not a valid number. Once all 10 integers are added it prints the Average of the values entered.

import java.util.ArrayList;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int count = 0;

       int sum = 0;

       while (count != 10) {

           System.out.println("Enter a number: ");

           String answer = in.nextLine();

           try {

               int intAnswer = Integer.parseInt(answer);

               sum += intAnswer;

               count += 1;

           } catch (NumberFormatException e) {

               System.out.println("Not a valid number.");

           }

       }

       int average = sum / count;

       System.out.println("Average: " + average);

   }

}
