hi all

 Can anyone tell me .. when we implement a class with two interfaces which have same methods.. which reference the class will take?


public interface Interface
 function fun() as string
 end function
end interface

public interface Interface1
 function fun() as string
 end function
end interface

public class : implements interface,interface1

public function classInter()As String Implements interface1.fun,interface.fun
      /* implementation */
end function
end class

This is the case.... here the ClassInter implements the fun() from which interface?
regards
Ratheesh
