Abstract FactoryPattern abstractfactory

Abstract Factory mode: provides an interface for creating products to create related or dependent objects without specifying specific classes.

Abstract factories support the "open-closed" principle for changes to a series of products (that is, the system is required to be open to expansion and closed to modification), which is very easy to expand, however, the "open-close" principle is not supported when new products are added.
