         System.out.println("Enter four numbers");

         Scanner s = new Scanner(System.in);

         n1 = s.nextInt();

         n2 = s.nextInt();

         n3 = s.nextInt();

         n4 = s.nextInt();

         s.close();

         sum = n1 + n2 + n3 + n4;

         average = sum / 4.0;

         product = n1 * n2 * n3 * n4;

Answer 2

Question:-

Write a program to input 4 numbers and calculate and display the sum, product and average of 4 numbers.

Program:-

import java.util.*;

class Numbers

{

public static void main(String s[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter 4 numbers.");

double a, s=0,av, p=1;

for(int i=1;i<=4;i++)

{

a=sc.nextInt();

s+=a;

p*=a;

}

av=s/4.0;

System.out.println("Sum is: "+s);

System.out.println("Average is: "+av);

System.out.println("Product is: "+p);

}

}
