The factory model has the following forms: · Simple factory: Also known as the static factory method mode; · Factory method: Also known as polymorphic factory or virtualconstructor ); · Abstract Factory mode (Abstract Factory): Toolkit mode (kit or Toolkit ); Simple FactoryPurpose: Defines an interface for creating objects. Class DiagramAs follows: Let's take a look at itsComposition: 1) Factory role (creator): This is the core of this model and contains some commercial logic and judgment logic

by a specific class in java.How can we use the simple factory model? Let me give you an example. I think this is much easier to understand than a large theoretical text description! Let's take care of the nouveau riche: PAfter using the simple factory model, the nouveau riche now only needs to sit in the car and say "Driving" to the driver. Let's see how it is implemented:// Abstract Product rolePublic interface Car {Public void drive ();}// Specific product rolePublic class Benz implements Car

Design Pattern-Rule Pattern Concept: Policy patterns define a series of algorithms that are encapsulated separately so that they can be replaced with each other. This mode changes the algorithm and does not affect the customers who use the algorithm. Policy actually refers to an algorithm. Example: A fresh and simple example can make it easy to understand obscure concepts. Let's take a look at a strategy model about auto prices. We know that the brand and quality of a car determine its price. Li

Product role: it is generally the parent class or implemented interface inherited by a specific product. It is implemented by interfaces or abstract classes in java. 3. Specific product role: the object created by the factory class is the instance of this role. It is implemented by a specific class in java.How can we use the simple factory model? Let me give you an example. I think this is much easier to understand than a large theoretical text description! Let's take care of the nouveau riche:

The simple factory model is one of the factory models. There are three factory models: the simple factory model, the factory method model, and the abstract factory model, that is, all object creation tasks are handed over to the factory. From the simple factory mode to the abstract factory mode, the abstract level gradually increases. The factory model consists of three parts: the factory role, the abstract Product role and the specific product role. The factory role is the core of the factory m

Fu's car is a big brown space BMW, more than 1 million purchases, men driving such a car, very face-recognition, not a successful person, General white-collar companies, where can I start a car like this? Yan Fukai opened the BMW, and his heart was very proud. Almost every girl he wanted to soak in, after sitting on his car, will reveal a kind of admiration and envy, wishing she could not immediately becom

Condition testThe core of each if statement is an expression with a value of ture or false, which is known as a condition test. Python determines whether to execute the code in the If statement based on the value of the condition test as ture or false. If the value of the condition test is Ture,python, the code immediately following the IF statement is executed, and if it is False,python, the code is ignored.string comparisonstring checking is case-sensitiveCheck for equality"

The function of an array object is to store a series of values using a separate variable name.Create an array and assign it a value:Instance var mycars = new Array (); Mycars[0] = "Saab"; MYCARS[1] = "Volvo"; MYCARS[2] = "BMW"; What is an array?an Array object uses a separate variable name to store a series of values.If you have a set of data (for example: car name), there are individual variables as follows: var car1= "Saab"; va

In a recent training session with Huawei, the lecturer asked the student a question: what is the difference between the sample and the product?This is an interesting question, it is difficult to give persuasive answers simply from the perspective of research and development, production and marketing. A more general view is that the mass production is the product, the experimental small amount of produce is the sample. Is that so? Let's analyze it. Once I was asked what the difference between sa

The location where this resource is placed is usually used to launch the application. ==> detailed content 2. With the hybrid reality of Microsoft, the future designers are doing this on-site design! Microsoft recently unveiled a two-pronged approach to VR (virtual reality) and AR (Augmented R

time. AR is partially overlapping in the current phase and holographic projection technology (Hologram): (In fact, Microsoft uses the word holo rather than AR in its AR device). Traditional Holographic projection technology refers to the use of optical techniques to achieve a complete, can be viewed from 360 degrees of virtual image, usually relying on multi-directional observation of multiple-face equipment and a number of different angles of proje

direction will weaken and become polarized. Therefore, the reflection on the smooth object surface and the diffuse light of the sky are polarized light, the light affects the clarity of photographic imaging. The polarized mirror can choose to let a direction of vibration through the light, so the use of a polarized mirror can reduce the reflection of the object surface, can highlight the blue sky and white clouds and dark sky, in the still life photography and landscape photography, polarizatio

always an initial app view (app view) and any number of other secondary views you want to create. For a desktop environment, you can think of an app view as a window. Our Holographic Application project template will create a unity project in which the initial view is a holographic view. Your app can use techniques like XAML to create additional 2D views to use shell controls such as in-app purchases. If your app starts in a generic application, the initial view will be 2D, but you can add an a

projection is the future of projection. Designer Mac Funamizu designed the revolutionary concept of a mobile phone using holographic technology, the screen part of the phone is a hole, using holographic technology to generate images, so that you can not only see each other on the phone, but also see the other side of the 3D image, you can rotate from different angles of view, It's like a real scene. You can also view Google's three-dimensional maps through such techniques. Fig. 5 Trou
