Thanks to the authors of the following two articles. Let's look at the second one from the first example, which is very clear! The code is slightly changed, just for your convenience in the future, please forgive me!

Adapter
Converts an interface of a class to another interface that the customer wants. The adapter mode allows classes that cannot work together due to interface incompatibility.
The object-oriented spirit is to better cope with changes

I recently started to look at the design model. I think about what I should have known when I was in college. Now I only know what I think ~~~
This is an example of a calculator. Now I want to create a calculator that includes addition, subtraction,
The design patterns in the software field provide developers with an effective way to use expert design experience. The design patterns use the important features of object-oriented programming languages: encapsulation, inheritance, and polymorphism.

The factory method mode is an improvement on the simple factory mode. First look at the shortcomings of the simple factory model.Software is different from programs because it can be used by people and indirectly create benefits. Demand is the core

The Observer model solves the problem of creating a one (Subject) dependency on multiple (Observer), and doing so when "one" changes, depending on the number of "one" can also be synchronized.
