Name that tune

Posted by Jody Brown on November 28, 2001 at 2:45 PM

The problem is in the tune method defined in WindError. The tune method takes a parameter of type InstrumentX. Because there is no play method on InstrumentX that takes a NoteX, an error is thrown. An explicit cast is needed on the incoming InstrumentX object to cast it to a WindX object. Then you can call the WindX's play method.
