I have the following Classes in the same package but when I attempt to
compile, this error
is shown for all the methods to be implemented :

" The methods a(),b(),c() can not be implemented in Interface
TLCNavigatorMethods with weaker access privileges, was public"

Does anyone knows whats going on here ?

thanks

file #1 TLCNavigatorMethods.java
=========================
package TLCPanel;
interface TLCNavigatorMethods {
  void a();
  void b();
  void c();
}

file #2 TLCNavigatorControl
====================
package TLCPanel;
import borland.jbcl.control.*;
class TLCNavigator extends NavigatorControl implements TLCNavigatorMethods
{
  TLCNavigator() {
     // all Common Initialization could be added here
     super.setButtonEnabled(0,true);
  }
  //Implementation of Interface TLCNavigatorInterface just an example the
actual method will
// do  something different.

    void a()
    { super.updateUI();}
    void b()
    { super.updateUI();}
    void c()
    { super.updateUI();}

}
