definition: enables multiple objects to have the opportunity to process requests, thereby avoiding coupling between the sender and receiver of the request. Connect the objects into a chain and pass the request along the chain until an object handles it.Type: behavior class patternclass Diagram: First look at a piece of code: public void Test (int i, request request) { if (i==1) { handler1.response (request); } else if (i = = 2) { handler2.response (request); } else

,month,day from the Birthdate class by combining. Inheritance is portrait, and the combination is horizontal. If you define a Professor object Prof1, it is clear that Prof1 contains information about birthdays. This method effectively organizes and utilizes the existing classes, greatly reducing the workload. If there is void Fun1 (Teacher ); void Fun2 (birthdate ); Call these two functions in the main function: FUN1 (PROF1); Correct, the parameter is a

There are two types of data in C #: Reference types (reference types) and value types (values types)In fact, you don't have to understand how complicated!You just have to know that if you use ref, the same variable is being manipulated,So it changes the value, and if it doesn't work with ref, it's not the same variable, so the value doesn't change.It's all right! Others, after learning in depth, you will un
