Question

In Java Design a simple program that will prompt and get a series of integers from the user. The first

integer is special in that it indicates how many integers will follow. Once your program has

received all of the integers, compute and display the sum, the largest number entered, the

smallest number entered,and the average for all of the numbers entered.

Answer 1

import java.util.Scanner;

public class SeriesIntegers {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int min = 0, max = 0, count = 0, n;
       double sum = 0;
       boolean flag = true;
       System.out.println("Enter integer (-1 to quit): ");
       while (true) {
           n = sc.nextInt();
           if (n == -1)
               break;
           sum += n;
           count++;
           if (flag) {
               flag = false;
               min = n;
               max = n;
               continue;
           }
           if (n > max)
               max = n;
           if (n < min)
               min = n;
       }
       System.out.println("Sum of elements: " + sum);
       System.out.println("Average of elements: " + (sum / count));
       System.out.println("Largest element: " + max);
       System.out.println("Smallest element: " + min);

   }
}
