The goal of the framework is to define a process that allows developers to implement certain functions based on person

Whether your project is using swing technology or not, I would say that swing is a well-designed Java package that is filled with the wisdom of the master. If you learn Java and you can't write a button, it's just as if you're learning Visual Basic and you don't use a button, which is absolutely unforgivable. Swing technology has been used in foreign countries, because of the free Java, easy to learn and the full trust of Java technology, a lot of companies early on the application of everything

I will upload my new book "self-writing processor" (not published yet). Today is the eighth article. I try to write this article every Thursday. 2.7 Circuit Design Example In this section, we will design a simplified processor command acquisition circuit, through which we can use the example to understand the use of T

process development is often different from the timer used in industrial control or algorithm. The timer used in industrial control or algorithm must be accurate, however, the timer of a business flow may require work days, efficiency, and other functions. It can reflect business time and cycle changes, so that business processes can run, manage, control, and count based on specific time coordinates. I will define it as a time engine. The time engine consists of two parts: Timeline, including

The Observer pattern is one of the software design patterns, and is more common, especially in GUI programming. On the design model of the article, the network wrote more, and a lot of writing is good, although there is a repetition of the early wheel of suspicion, but this wheel is not that wheel, the focus is different, the idea is different, the way is not nearly the same.key Elements Theme: Subject is

In today's web design, blue has become the dominant color.In the following example, we will show you how to use blue to help your website stand out. Examples of using purple in Webpage Design Case study of using purple in Webpage Design Use of white in Webpage Design

0. Suppose an existing project (Duck) encounters an issue that adds functionality to a class, how do I design a class to add new functionality?1. What are the disadvantages of using the duck (duck) provided by inheritance? (1) Code repeats in multiple subclasses (2) Many men know the whole behavior of all ducks (3) The behavior of the operation is not easy to change (4) Change will lead to the whole body, causing the other ducks d

shouldn ' t use breadcrumbs for single-level websites that have no logical hierarchy or grouping. A great way to determine if a website would benefit from breadcrumb navigation are to construct a site map or a diagram rep resenting the website's navigation architecture, and then analyze, whether breadcrumbs would improve the user ' s ability to Navigate within and between categories. Breadcrumb navigation should is regarded as an extra feature and shouldn ' t replace effective primary navigati

In the final analysis, there are two aspects to the design of a relational table. First, it is designed completely according to the paradigm theory. Generally, it is enough to reach the third paradigm, or you can divide it to a further level. For example, the fourth and fifth In the final analysis, there are two aspects to the design of a relational table. First,

1. Collect and analyze Application Requirements A. I used a UML case in this example. I feel that the design idea is very clear, but I don't know if I can analyze it myself if I put it in front of me. In short, I think that with the use case document, the code after writing is as simple as building blocks. B. The main content of the case document is: ① preconditions; ② main event stream; ③ other event str

In JavaScript, a single example pattern is one of the most basic and often used design patterns, and may inadvertently be used in a single case pattern.This article will start with the most basic theory, the basic concept and implementation of the single case model, and finally use an example to describe the application of the single case pattern. Theoretical ba

The last time I wrote a system architecture based on MVC pattern and command mode, I also made a simple example. After writing what I want to write, I want to use a specific project to concatenate most of the design pattern ideas. What I want to say today is the single piece mode. First of all, a simple description of what is a single piece mode, also known as Singleton mode, to achieve a single instance

other non-primary key attributes depend on the primary key, then this property is indirectly dependent on the primary key, which is known as passing dependent on the primary property. Popular understanding: A table with up to 2 layers of the same type information eg: Dad table, not meet the third paradigm Father Son Daughter Little Bear of the daughter Daughter's SpongeBob SquarePants Change to dad informatio

C#winform parent window inside panel container embedded subform, program main Form Design exampleIn the project development often encountered the parent form Embedded subform So wrote an example program, by the way probably divided the next interface module and color, the shortcomings also look at the guidanceThe main form form uses the previous blog to design a

Abstract factory belongs to the creation design patternDesign Intent: Provides an interface that can create a series of related or interdependent objects without specifying their specific classes.Light look at the design intent some abstract, not good understanding, let us take a look at the example class diagram, combined with the class diagram we do a concrete

Singleton design pattern: Resolves a class that only has one object in memory.(1) Want to ensure that the object is unique.A) to avoid excessive creation of such objects by other programs. Prevent other programs from setting up this type of object firstb) Also for other programs to have access to the class object, in this class, you can customize an object.c) To facilitate the access of other programs to custom objects, you can provide some external a
