: Delegation is the packaging of methods. It is used when you are not sure when you want to call a method, but cannot be implemented using abstraction or polymorphism.
Example of delegation in Observer mode:

Public interface PilotLamp{/// /// Green light/// Void TurnOn ();
/// /// Notice/// String Notice{Get;Set;}}
Create DelegateEvent. cs again:
Public delegate void EventHandler (); then create TrafficLight. cs:
Public class TrafficLight: PilotLamp{Public event Event

Not only has the native system been discarded, but many new features have not landed. The new Android P, which was unveiled at the Go
