Name The Abstract Factory structure intent provides an interface to create a series of associated or interdependent objects without specifying their specific classes. applicability
A system is to be independent of its product creation, combination, and representation. A system is to be configured by one of a plurality of product lines. When you want to emphasize a series of related product objects for union use. When you provide a product class, just want to display their interfaces instead of implementation.
An important role is to change the appearance of the application. Let's take a look at the example of an abstract plant mode in the application layer. Suppose you bought a residential, there is a garden on the roof, and you need to design a garden layout. There is a flower stage on the right side of the garden, and a plant is needed, and the center needs a substrate plant. According to the style, the garden can be designed as elegant, used and lazy. This is changed by the Java example of others.
