I. Adapter Mode
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.

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

Today, we're going to comb the adapter pattern for Java design mode. Adapter, think of our usual use of the power adapter to know, is to put two incompatible things straightened out, can contact each other. Also in Java, is to let two need to coordinate the class, through the adapter to coordinate the line, that is,

In real life, we also often use adapters, which are similar to the commonly used computer adapters. You don't need to charge the adapters, but we found that the computer adapters are also qualified, first, you have to have electricity. If there is no electricity, there will be no Adapter. Second, you have to have

Why do we often encounter the combination of two unrelated classes when using the adapter mode? The first solution is to modify the interfaces of the

In common View (Listview,gridview) and other places need to use adapter. such as the intuitive expression of data, Adapter, view the relationship between the three:All adapter
Usually we often encounter this situation, there are two of ready-made classes, there is no connection between them. But we now want to use one of the methods of the class. At the same time, you want to use a different class method. There is one solution. Changes to their respective interfaces. But this is the last thing we want to see. This time, adapter mode will come in handy.There are three ways of adapter
The function of Adapter pattern is to convert the interface without changing the function. Adapter is divided into two categories, one is Object Adapter, and the other is class Adapter. Because the implementation of class Adapter requires multiple inheritance, and Java does

I haven't written any articles for more than half a month. It's mainly because there are a lot of messy things in my senior high school, hitting the wall for a job. We also blame ourselves for the poor strength, but also for the lack of practical experience, which is difficult to attract HR interest. So I am still making a small advertisement here. I hope any one of

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

Converts an interface of a class to another interface that the customer wants. The A d a p t e r mode makes those classes that cannot work together due to interface incompatibility work together.
2. Applicability
Use the d a p te r mode in the following cases
• You want to use an existing class, and its interface does not meet your needs.
• You want to create a reusable class that can work collaboratively with other unrelated classes or unforeseen classes (that is, classes that may
