specify various standard Java classes, such as iterators, wrappers, and collection classes. Although the sequence diagram can show the loop and branch structure to be used, it is generally better for readers to read the Java source code under the guidance of the sequence diagram. Figure 4 uses together controlcenter to reverse engineer the complete () of the sale class and asks it to provide the sequence diagram obtained by all the detailed information. For most people, there may be too many de

The development of Object-Oriented Analysis and Design (OOA D) methods has seen a climax from the end of 1980s to the end of 1990s. UML is the product of this climax. It not only unifies the Expression Methods of booch, Rumbaugh, and jacbson (father of UML: three persons), but also makes further development on it, and finally unified it into a standard modeling language accepted by the industry. The emerge

First, let's talk about why we want to convert the format. The HTML format can be viewed through the web page, which is convenient for those who have not installed the software about UML. I sent a picture to my master, and he said that he would change it to HTML format. How can this problem be solved? It's ration.If Rose comes with this function, it still needs to be converted through other software. Master said Rose can be directly transferred. Let's

The basic structure of UML. Several types of relationships in UML: inheritance, implementation, dependency, association, aggregation, and combination. Use case diagram (usecase di#)-UML diagram (1) Class digraphs-UML diagram (2) Object digraphs-UML diagram (3) Activity digra

programming language code, or use a reverse Generator tool to convert the program source code to a UML model. It includes two concepts: semantics and representation. (1) semantics describes UML-based Precise meta-model definitions using natural languages. The meta-model provides simple, consistent, and general definitions for all UML elements in terms of syntax

First, as a modeling language, the definition of UML includes two parts of UML semantics and UML notation. UML semantics: Describes the definition of exact meta-model based on UML. UML notation: Defines the representation of

Object-Oriented Analysis and Design have suddenly emerged, software Enterprises are transitioning from process-oriented to object-oriented. On the other hand, rose embodies the advanced design ideas of Unified Software Modeling (UML), and can express various design ideas in a concise and effective manner through a unified set of graphical symbols. Of course, the commonly used

, We often use it in software development, in fact, other modeling areas can also be used. For example, if we want to model our home appliances, it is clear that we may need graphic symbols for television, or graphical symbols for set-top boxes, and these graphic symbols related to the application area are not fully defined in

First, some questions are raised: What is the full name of UML? Why is UML? Origin and Development of UML Unified Modeling Language. From multiple sourcesObject-Oriented Modeling MethodIt is a tool for visualizing, detailing, structuring, and documenting systems. Developed by OMG, it has become an industrial annotation. The object-oriented modeling language firs

graphs drawn in two different styles. The first one is complex and has no rules, while the second one is simple and well organized (although tedious ). Which one do you think is better? Most people will agree that the second one looks better, because although the two designs are functionally equal, the second arrangement is more neat.

I hope you will have some knowledge about the UML class diagram symbols through this section, next let's take a look at the detailed introduction of
