specific subclass of the factory class.Cons: Each time a new part is added, the design of the abstract factory class needs to be modified, and all the specific factory classes that implement this abstract factory class need to be modified, and additional coding is required to increase the amount of code. If the number of products created in each abstract factory class is very large, it can be complicated when the client assembles objects created by each specific factory, resulting in a very lar
