Then, you only need to use Class D to inherit Class B and implement the absmethod (c) Method of class B. In this way, you can indirectly pass the C instance to the methoda () method.This blog does not explain the template design pattern, but emphasizes how

Statement in advance: I am referring to Chen and Wang Bin's "grinding design mode" for the study of design models. I am reading this book carefully and think it is quite good.
