class AverageCalculation

{

  double avg=0;

 

  AverageCalculation(int a[])

  {

     for(int  i=0;i<a.length;i++)

     {

       avg=avg+a[i];

     }

  }

}

 

class AverageMarks

{

 public static void main(String args[])

 {

   int i;

 

   System.out.println("Enter number of subjects");

 

   Scanner sc=new Scanner(System.in);

 

   int n=sc.nextInt();

 

   int[] a=new int[n];

 

   System.out.println("Enter marks");

 

   for( i=0;i<n;i++)

   {

     a[i]=sc.nextInt();

   }

 

   AverageCalculation c=new AverageCalculation(a);

 

   System.out.print("Average of (");

 

   for(i=0;i<n-1;i++)

   {

    System.out.print(a[i]+",");

   }

   System.out.println(a[i]+") ="+c.avg/n);
