Hello,

When I compile the code below, I've got the following error :

It seems this comes only from the "package" method.

The error is the same with this code :
/* --- CODE --- */
interface I
{
    package void setFunc(int);
}


class A:I
{
   int i;

   package  void setFunc(int i)
   { this.i = i ; }

}


void main()
{

   I a = new A;
   a.setFunc = 10;

}
/* --- END CODE --- */

I'm not sure but I think package is not virtual.

The compiler should catch that then.

Last time I checked I could even use "override" to... erm, override 
methods that had package protection. The compiler didn't even complain, 
and I had to find out the hard way that the method wasn't virtual.

:-(
So there's really no way to have a method declared "package" in an  
interface ?

You also can't have a private function in an interface.  This once lost
me four days trying to figure out why my program wouldn't link despite
the function very obviously being there.

Stick to public functions only.

Double thanks! I ran into this issue just a day or two ago.
