Introduction of Adapter Mode (Brief Introduction)
Adapter mode to replace a class with another interface expected by the customer. The adapter mode makes it possible for those classes that are not working because of incompatible interfaces to work together.

The first few introduced the characteristics of design patterns and explained in detail the 4 creation patterns, which are responsible for generating object instances, followed by architectural patterns.
first, what is the structure of the model ?
The structure pattern is the internal structure and the external combination of the Analytic class and object, and solves the coupling problem between modules by optimizing the program structure.
second, the type of structural model :
The adapter mode transforms the interface of one class into another interface that the client expects, so that two classes that would otherwise not work together because of an interface mismatch can work together.Structure of the adapter patternThe adapter mode has two different forms of adapter mode for the class and

Overview
In software systems, due to changes in the application environment, we often need to put "some existing objects" in the new environment for application, however, the interfaces required by the new environment are not met by these existing objects. So how should we deal with this "Migration change "? How can we make good use of the existing object and meet the interfaces required by the new application environment? This is the Adapter mode des
I. Introduction
In the actual development process, due to the changes in the application environment, such as the changes in the use language), we need to implement that there is no existing object in the new environment to meet, however, such existing objects exist in other environments. So what if we call "existing objects" in the new environment? The solution to this problem is the adapter mode we will introduce in this article --In this way, exist

Problem Introduction: for example, if there are A-type and B-type nuts, you can directly use A-type screws produced by A-type nuts on a-type nuts, you can also directly use B-type screws produced according to B-type Nut standards on B-type nuts. However, because a-type nut and B-type nut have different standards, you cannot directly use B-type screws on A-type nut, and vice versa. How can we achieve this goal?
You can solve this problem by using an adapter
The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that the original interface does not match and cannot work together can work together.
Name Origin
This is like a transformer, which converts one voltage to another. The domestic electricity voltage in the United States is 110 V, while that in China is 220 V. If you want to use us appliances in China, you must have a transfor
that uses Entryiterator traversal, and the iterator operates directly on the HASHMAP internal storage structure table. This approach enables the functionality of the view. The entire process does not require any secondary storage space.
P.s. From this point you can also see why EntrySet () is the most efficient way to traverse HashMap, because it is consistent with the way it is stored within HASHMAP.
Note: Effective Java says that the adapter dele
Structural patterns (structural pattern) describe how a class or object can be combined to form a larger structure. The structure pattern describes two different things: a class and an instance of a class. According to this point, the structure pattern can be divided into the structure pattern of the class and the structure pattern of the object.

Adapter mode design ideas in life will often be applied to, such as when we are charging the phone, it is not possible to directly charge on the 220V power supply directly, but with the mobile phone charger to convert the voltage required to be able to charge the normal, otherwise it can not be completed charging, the charger has played a role in adaptation.1.

First, IntroductionFrom today onwards we begin to talk about "structural" design patterns, "structural" design patterns are as follows: Adapter mode, bridge mode, decorative mode, combination mode, appearance mode, enjoy meta-mode, proxy mode. The "created" design pattern solves the problem of object creation, and the "structured" design pattern solves the problem of the combination of classes and objects. Today we start talking about the first design
