I. Structural Figure 2, applicability 1, one application is independent of one product creation, combination; 2, an application should be configured with a product in multiple products; 3, when you want to emphasize a series of related The design of the product object is designed to be combined; 4. When you provide a product class library, just want to display their interfaces instead of implementation. Third, the purpose provides an interface that creates a series of related or interdependent objects without specifying their specific classes. Fourth, personal feelings abstract factory model should be used in combination. When you build another object with different objects, you can make these all abstractions to facilitate more sample combinations; this guarantees the diversity of objects, the scalability of the program Enhanced; in addition, some methods can be encapsulated, forming an interface, and performs an implementation of an interface by configuring or otherwise. and many more. 5.
