   {
   int [] n = new int [101];
   int nums,grd, max=0,min=n.length;

   System.out.print("Enter The Number Of Students: ");
   nums=ip.nextInt();
for (grd=1;grd<=nums;grd++)
   {
   System.out.print("Enter The Grade For Student "+grd+": ");
   n [grd]=ip.nextInt();
   tot=tot+n [grd];
   }
   aver=tot/nums;
   System.out.println("The Average is "+aver);
for (int mi=1;mi<=nums;mi++)
   {
   if (n [mi]<min)
   {
   min=n [mi];
   }
   }
   System.out.println("The Minimum is "+min);
   for (int a=0;a<=nums;a++)
   {
   if (n [a]>max)
   {
   max=n[a];
   }
   }
   System.out.println("The Maximum is "+max);
   }
}
