You just provide one implementation. There is no way to have 2 different implementations for a method with the same name and signature, even if you implement 2 different interfaces that declare that method. In the few cases where this has been an obstacle for me, I just created adapters and factory methods on the object to provide an appropriate adapter rather than implementing the interfaces directly. > -----Original Message----- > From: Ronald Bourret [mailto:rpbourret@r...] > Sent: Friday, October 26, 2001 2:34 PM > To: xml-dev > Subject: Java: interface methods with same name and > signature > > > Sorry about the non-XML topic... > > Suppose I have two interfaces, both of which have a method > with the same > name and the same signature.
