//Write a java program that reads N integer numbers from the keyboard then calculate sum and average of them.

package sum_average;

import java.util.Scanner;//Needed for class Scanner

public class Sum_average 

{

    public static void main(String[] args) 

    {

            //---Create a class Scanner for inputting data.---

            Scanner Keyboard=new Scanner(System.in);

            //---Print Enter the value of n : on the screen.---

            System.out.print("Enter the value of n : ");

            /*---N : represent numbers of inputting data from keyboard.---

              ---initial : take the initial value 1.---

              ---sum : represent sum of all numbers you entered from keyboard.---*/

            int N=Keyboard.nextInt(),initial=1,sum=0;

            while(initial<=N)

            {

                System.out.print("Enter number"+initial+" : ");

                sum+=Keyboard.nextInt();

                initial++;

            }

            double average=sum/(double)N;

            System.out.printf("\nSum=%d\nAverage=%f\n",sum,average);
