uml class diagram java

From: http://blog.csdn.net/onetree2010/article/details/6197463 In Visio, the relationship between the package and the class is the inclusion relationship. After the class is dragged into the folder of the package, the relationship is established. The binary Association symbol can be set to aggregation and synthesis.Interface: hollow circle + straight line (Tang Lao duck

PrefaceI have been using php for more than two years. I have prepared to write frequently-used design patterns based on my own practical experience. Of course, before using the design patterns, I must first understand the design patterns, therefore, we will first explain the UML class diagram. Through UML

class is responsible for coordinating other jobs. After learning about classes and class diagrams, I began to draw class diagrams. This is really a headache. When I was writing a document, I felt very eager to draw a UML diagram, because it was useful at that time, but no

Class diagramThe class diagram shows the construction module of the object-oriented system. Depicts a static view of a model or part of a model, showing the properties and behaviors it contains, rather than describing the function or refinement of the operation in detail. Class diagrams are most commonly used to expres

, after reading the above description, we should understand the relationship between the relationships and specific to the code is how, so-called repetition, is only the above extension, such as A and B has a "1-to-many" of the repetition, there is a list in a, which holds the B object's n references , that's it.Well, to here, already put the above diagram of the relationship is finished, I hope you can have some gains, I also spent a lot of time ah (

In the specific business logic, logwapper needs logs to assist with the completion of a specific task, which is also dependent. Class "recursion" relationship and "Triangle" Relationship Recur

directly with each other, then these two classes should not have direct interaction, and if one of the classes needs to invoke a method of another class, the call can be forwarded through a third party. The fundamental idea of this principle is to emphasize the loose coupling between classes, and the weaker the coupling between classes, the more beneficial the reuse, the more weakly coupled class is mo

In UML class diagrams, the following relationships are common: Generalization (generalization) Implementation (Realization) Association (Association) Aggregation (Aggregation) Combination (composition) Dependency (Dependency) The order of strength of the various relationships:Generalization = implementation > Composition > Aggregation > Association > dependenciesFirst, gene

UML class diagram relationships include association, aggregation/combination, dependency, and generalization (inheritance ). The Association is divided into two-way Association, one-way Association, and self-Association. Let's take a look at what these relationships are and what their differences are. 1.

, the object as a local variable, call the static method of the class. The class that is called within the parentheses of a class function is dependent on itself. Because this relationship is weakly connected, from the point of view of high cohesion and low coupling, such code is optimally organized, whether it is object-oriented or process-oriented.There is a sp
