One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.

At the beginning, No one has linked these big wasps to the Vietnamese army. However, everyone knows that it is definitely not a good thing for this kind of thing to fly over. I also don't know who it is. I shouted a "fight" at the top of my voice. This loud cry is called a big one. I can actually hear it very clearly through the interference of the "buzzing" sound.
