At this time, the idea was gradually clarified, recalling some of the experiences and five principles described in Uncle Bob's book.I gradually realized that refactoring is not useless or correct.Code.

In the Internet cafe a few days ago, use flashget to download msdn webcast and save it to a new folder.
Go home and open it. You can see that each folder has two identical names. The two folders with the same strange names exist in one folder.
Go to the folder and find that the downloaded items are invisible... a headache.
There is no way to delete one of the two folders with the same name, and then enter another folder, and find that the downlo
Factory mode: I personally think it is mainly used to create n object instances in the same series. (Note: "the same series" indicates that all objects inherit from an abstract class or all implement an interface)

This is a behavior-oriented design model that is widely used.
Objects may often need different typesAlgorithm, But if the change is frequent, the type will become very fragile.
As shown inCubeTake, take different cross sections, then its area calculation method will be different, need to use different algorithms.
So, how can we design Algorithms Dynamically without changing the method during runtime? Deco

New Problem: Implementing dependencies cannot cope with changes in the specific instantiation type. (When the instance object changes, it cannot meet the requirements)
Example:
When a road is prone to change and may become a mudroad, You need to modify all the new to road locations in the system.
Solution:
Closed change point-where to change and where to close; if the new type is relatively stable, there
