The first few introduced the design pattern characteristics and explained in detail 4 kinds of creation pattern, the creation pattern is responsible for how to produce the object instance, next talk about the structure pattern. first, what is the structural model ? Structural pattern is the internal structure and external combination of analytic classes and objects, and solves the coupling problem between modules by optimizing the program structure. ii. types of structural patterns :

?Adapter mode: the interface of a class is transformed into another interface that the customer expects, and the adapter lets the originally incompatible classes work together seamlessly.appearance mode: provides a unified interface for accessing a group of interfaces in a subsystem. The appearance defines a high-level interface that makes the subsystem easier to use.?Object adapter:Class
