From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object.

It happened that he refused to show weakness. Take a step back and you won't die. When you have the chance, you can return it well.
