A program based on policy mode consists of at least two parts. The first part is a set of policy classes, which encapsulate specific algorithms and are responsible for specific calculation processes.

The core idea is: when the state of the object changes, it changes its behavior at the same time, which is very understandable! Take QQ for example.

In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused.
