Yesterday, I demonstrated a simple delegated application, and there are some more complicated delegated applications or delegated changes ~ For classes with inheritance relationships, we can use the delegate covariant to avoid setting up the delegate type of a subclass to only return the method of this subclass ~ The covariant allows a method to have more derived return types than those defined in the delegate. The inverse method allows fewer derived parameter types than the delegate type-from M

James's city had a heavy snow last night and all the roads were covered with snow. In order to ensure smooth traffic, snow removal vehicles need to be used to clean up the snow on the road, but the city only has one snow removal vehicle.There are two lanes for each road in the city.
