   public static void main(String[] args)
   {
   int sum = 0;
   float average;
   Scanner s = new Scanner(System.in);
   int a[] = new int[5];
   System.out.println("Enter the 5 elements:");
   for(int i = 0; i < 5 ; i++)
   {
   a[i] = s.nextInt();
   }
   for(int i = 0; i < 5 ; i++)
   {  
   sum = sum + a[i];
   }
  
   System.out.println("Sum:"+sum);
   average = (float)sum / 5;
   System.out.printf("Average: = %.2f ", average);
   }
}

output:

Enter the 5 elements:
