uml diagram java

: This article mainly introduces how to understand the uml class diagram. if you are interested in the PHP Tutorial, refer to it. In a UML diagram, there are several common relationships: Generalization, implementation, Association, Aggregation, and Composition ), dependency) 1. Generalization) [Generalized relationsh

class. In an aggregation relationship, the subclass instance can be longer than the parent class. to present an aggregation relationship, draw a solid line from the parent class to the partial category, draw an unfilled prism at the end of the parent class association. 2. Combined Aggregation A combination of aggregation relationships is another form of aggregation relationships, but the lifecycle of a subclass instance depends on the lifecycle of the parent instance. For example, a company cl

Objective UML is used to describe the entire design process of the system, and for this process produced a UML9 diagram: Use case diagram, Class diagram, object graph, collaboration diagram, sequence diagram, activity

Document directory Abstract: this is an article about the unified modeling language, that is, the basic diagram used in UML. In this article, I will discuss the structure diagram, which is a new graph type that has been proposed in UML 2. Since the purpose of this series of articles is to help people understand

There are many tools for painting class diagrams. I have learned how to use staruml to draw class diagrams. However, this tool is used in Java. For vs programming C ++, I personally feel that Using Visio is better. The following uses a block class in the previous Tetris game as an example to describe it. 1 class block2 {3 public:4 block (void );5 void Init (); // Initialization6 void newblock (); // create a square7 point * getblockdata (); // obtain

create a class drawing cloth for class design by selecting UML class diagram in.Class Diagram creation You can create a class diagram by using the tool box on the left, demonstrating the relationships of interfaces, classes, and classes: inheritance, dependency, aggregation, and composition. Enum is no

inheritance relationship. Child cases are similar to parent cases, but show more special behaviors. Child Cases inherit all structures, behaviors, and relationships of the parent case. A child use case can use a behavior of the parent use case or reload it. The parent case is usually abstract. [Arrow pointing]: pointing to the parent use case C. Include) 　　The include relation is used to break down the Functions Represented by a complex use case into smaller steps. [Arrow pointing]: points to

. Generalization (inheritance)Is the commonly understood inheritance relationship, where the child use case is similar to the parent use case, but behaves more specifically, and the child use case inherits all the structures, behaviors, and relationships of the parent use case. A child use case can use a section of the parent use case, or it can be overloaded. The parent use case is usually abstract.Arrow pointing to: pointing to the parent use caseC. Include (include)　　The include relationship

Because the actual results of the previous solution were not satisfactory and did not match the initial project reported to the teacher, I switched to the original idea here to continue the game. We still plan to use the unity engine for development, but due to the characteristics of one stroke, this finished product should be a 2D horizontal version of the platform to solve the puzzle class game, the following project is the demand and UML

Design Mode Study Note 1: UML class diagram The UML class diagram is the basis for learning the design pattern. Through the UML class diagram, you can better communicate with everyone and easily express your own design ideas. It

Generalization relationship (generalization)The inheritance structure of a class is represented in UML as: generalization (generalize) and implementation (realize):The relationship of the inheritance relationship is is-a, and if the two objects can be represented by is-a, it is an inheritance relationship: (.. Be ...)Eg: Bicycles are cars, cats are animalsA direct representation of a generalized relationship with a hollow arrow, as indicated (a inheri

Component diagram, English name Yue: Component diagrams is used to describe the organization and dependencies between a set of artifacts, for the static implementation view of a modeling system, which can be executable programs, libraries, tables, files, and documents, and includes implementation information for logical classes or logical classes. Therefore, there is a mapping relationship between the structure model view and the implementation. Comp

Package diagrams is a combination of model elements that are represented in UML in a notation similar to a folder, each element in the system can be owned by only one package, one package can be nested in another, and a package diagram can be used to classify the related elements into a system that contains a package, chart, or individual element. In simple terms, we can directly understand the package as a

The UML activity diagram records the logic of a single operation or method, a single user case, or a single business flow. To create a UML activity diagram, perform the following steps repeatedly. Step 1: define the scope of the activity diagram. First, define the modeling

This article begins with a discussion of code-level issues. The main feature of Markdown is the design implementation.This article begins with the markdown perimeter code:UML sequence diagrams are obtained from https://github.com/bramp/js-sequence-diagrams copy.When this UML code also uses two JS, function library and drawing.First of all, talk about this JS core class:Https://github.com/bramp/js-sequence-diagrams/blob/master/src/sequence-diagram.jsFi

arrows can only be nouns or noun phrases, and the entire graph does not reflect the order of execution of the processing.③ generally do not draw material flow. Data flow reflects the data that can be processed by computer, it is not physical, so the flow chart of the target system is generally not to draw material stream.④ has at least one input data stream and one output stream per processing, reflecting the source and processing results of this processing data.⑤ number.

statements at the common layer once. If you do not need the common layer and the same SQL statements are used more frequently, You need to modify each statement at the time of modification, it is prone to errors. Layer B is a logical combination of methods in layer D classes to complete a function. It can be said that a specific use case requires a class or method in layer B. Of course, sometimes layer B does not need layer D. The time sequence diagram
