see the same is the creation of the car, the generator mode is much less than the abstract factory pattern of code a lot more, of course, in terms of decoupling or abstract factory is better, because the builder in the concrete builder in the build process of the product parts, If this process is more complex then the concrete builder will be very large and the error rate will be very high, and the abstract factory is better in this respect, each component is a separate building interface and c

Interview questions-java Design Pattern Example 1, adapter modeInvolves three roles: Target destination interface, Adaptee source role, adapter adapter,adapter The source interface to the target interface, inherits the source interface, and implements the target interface .Many examples of Java I/O operations are:InputStreamReader the inputstream to reader; you need to inherit inputstream to implement reade

1. Simple Factory Model IntroductionThe Simple factory pattern (simply Factory) is also called the "static factory method pattern." It belongs to the "Create pattern" (the schema that creates the object) and is a special implementation of the "factory method" pattern.Typically, we use a simple factory pattern to create a class. For example, getting a thread pool object is done through a simple factory pattern. Its structure diagram looks like this:

For the Observer pattern in design mode, the definition is as follows (Wikipedia): The Observer pattern (sometimes referred to as the release/subscribe mode) is one of the software design modes. In this mode, a target object manages all the observer objects that are dependent on it and, in its own state, changes the notification of the host. This is usually done by calling the methods provided by the viewe

A simple example of PHP interface-oriented programming coupling design mode. Copy the code as follows :? Phpinterfacejs {functionys ($ a, $ B);} classAfimplementsjs {functionys ($ a, $ B) {return addition operation ...... result :. ($ a + $ B) ;}} classJfimplemen The code is as follows: Interface js {Function ys ($ a, $ B );}Class Af implements js {Function ys ($ a, $ B ){Return "addition operation...

responsibility allocation principle, the whole creation logic is concentrated in a factory class, it can create the class can only be considered beforehand, if you need to add new classes, you need to change the factory class. As the number of specific product classes in the system increases, there may be a need for factory classes to create different instances based on different conditions.This judgment of the condition and the judgment of the specific product type staggered together, it is di

Php design mode command mode example This article describes how to use the command mode in php design mode. The command mode encapsulates a request as an object so that you can parameterize the customer with different requests; queue requests or record request logs, and supports unrecoverable operations Command class: 1. Command role: declares an abstract interf

The Observer pattern (sometimes referred to as the Publish/subscribe model) is one of the software design patterns.In this pattern, a target object manages all the observer objects that are dependent on it and actively notifies it when its state changes.This is usually done by calling the methods provided by the various observers. When implementing the observer pattern, it should be noted that the interaction between the observer and the observed obj

To give you Photoshop software users to detailed analysis to share the design of the Ant movie poster example of the production of a tutorial. Tutorial Sharing: Let's see the final effect. Official poster: After a thoughtful deliberation, I found a piece of work. Material: 1, first of all, we put the main body of the screen,

Microsoft Bing launched a lot of people feel that the search engine interface is different, not using a simple Google direct interface, but with a lot of beautiful pictures as the Web interface, of course, as Microsoft Bing, there are many interesting creative interactive design features. Microsoft's Bing has been in the game for some time, but it didn't feel like it before, but two days ago, accidentally found Bing's video search function very powerf

The purpose of the Singleton mode is to ensure that a class has only one instance, and does not provide a global access point. to prevent other workers from instantiating our class, You can create a unique constructor for the class and set the visibility of the builder to private. It's worth noting that if we create other non proprietary constructors, or simply do not mention the class For the constructor, then other people can still instantiate our class. If you do not want to create a single

This article will give novice white to introduce how to use HTML and CSS to make a simple registration page. In the process of developing the Web site, if the content requirements of the site is a perfect information station, then must be inseparable from the user registration of this feature. This user registration interface may be difficult for beginners who are just getting started. Then we will pass the specific HTMLCSS code example, detailed to

One, what is Smarty? Smarty is a PHP template engine that is written out of the template, it provides a separation of logic and external content, simply, the goal is to use the PHP programmer to separate from the art, the programmer to change the logical content of the program will not affect the graphic design of the page, The art of modifying the page does not affect the program logic of programs, which in many people cooperation projects is parti

Scenario: 1. for example, in interface development, communication is required between multiple windows. A common method is that each window contains references to other windows, then, when necessary, call the corresponding function to obtain the corresponding value through reference in other windows; However, this confirmation is obvious, that is, it will cause the dependencies and coupling between windows. It is okay to think about another window whe

create an instance of that class every time you need it, it obviously reduces the execution efficiency of the program, so you often put an instantiation of that class in a static{} , you only need to execute the first call and improve the execution efficiency of the program as follows:Static { try { configuration.configure (configfile); = configuration.buildsessionfactory (); Catch (Exception e) { System.err.println ("%%%% Error Creating sessionfactory%%%%"); E.printstacktrace (

Simulate a library with Java. This includes features such as creating books, creating readers, borrowing books, returning books, listing all of them, listing all readers, listing borrowed books, and listing books that have expired. Each reader can borrow up to 3 books, each book can only be borrowed for 3 weeks, more than even if it expires.This example adds Java 8-specific syntax compared to http://blog.csdn.net/yidinghe/article/details/3940437, incl

This article mainly introduces the simple program example of interpreter mode in Python Design Mode Programming. The Interpreter mode emphasizes the use of abstract classes to express the functions to be implemented in the program, if you need it, you can refer to the following pattern features: for a given language, define a syntax expression and define an interpreter. This interpreter uses this representa

This article mainly introduces the example of the factory mode in the javascript design mode. For more information, see Original javaScript factory Method Because the attributes of an object can be dynamically defined after the object is created, the following code will be written at the beginning of JavaScript introduction. The Code is as follows: Var oCar = new Object;OCar. color = "blue ";OCar. doors
