Solution
import java.util.*;
class PerfectAverage
{
public static void main(String arr[])
{
int i,j,n,s=0,c,p=0;
Scanner sc=new Scanner(System.in);
System.out.println(“Enter 10 integers:”);
for(i=1;i<=10;i++)
{
n=sc.nextInt();
c=0;
for(j=1;j<n;j++)
{
if(n%j==0)
c+=j;
}
if(c==n)
{
s=s+n;
p++;
}
}
if(p>0)
System.out.println(“Average of perfect numbers=”+(float)s/p);
else
System.out.println(“No perfect no.s present”);
}
}
