The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, the Unified Modeling Language). This course aims to show the highlights of UML. There are nine types of modeling icons in UML: Use case diagram

actually a class diagram. ② Behavior diagramThere are 5 behavior graphs:(1) usecasedi.pdf)The UML diagram uses a condition chart to organize the behavior of the system, describing a group of conditions, participants, and their relationships. The condition chart is used to describe the static usage view of the system. (2) sequencedigoal and collaborationdigoal)In

of being able to add multiple abstract methods with stronger representation capabilities. 3) Association class Like a class, association can also have its own attributes and operations. In this case, this association is actually an association class. An association class is both an association and a class. It connects two classes like an association, and can define a group of characteristics that belong to the association itself. Note: you can create an association class only when the objects

passed between the object classes that complete a behavior and those object classes. A sequence diagram is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the chronological order in which messages are sent between objects, and is used to represent the order of behavior in a use case. sequence

continue today to see the diagrams in the UML basic building blocks. a diagram of a UML basic building block A diagram of a UML basic building block is an abstract description of the system in a specific perspective. A graph is the classification of a collection of things,

Because of learning Java to do course assignments need to spend class UML diagram, online Search a lot of methods. This is the way to install the green plugin. Sometimes want to write our class to generate a UML diagram, is the code looks more clear, so we found a Java cla

, W runs in the application process, and winstate exists with the system Server process.1.5 Aggregation aggregations express the dependencies of two classes, but unlike composition, their lifecycles are different. A classic example is the factory and the car, the factory built, the factory closed, the car can continue to open, and vice versa. Policymanager and Phonewindow are similar relationships in the diagram.1.6 Inherritance is the most common i

UML

addition to providing a graphical border, framework components used in graphs also have important functions to describe interactions, such as sequence diagrams. In a sequence diagram, a sequence receives and sends messages (also known as interactions). A model can be established by connecting the message and the Framework Element Boundary (see figure 2 ). This will be described in more detail in the later section "Beyond basics. Figure 2: A Sequence

UML State diagrams and activity diagramsThe Unified Modeling Language UML (Unified Modeling Language) is a non-patented third-generation modeling and specification language. UML is an open approach for explaining, visualizing, building, and writing an open approach to an object-oriented, software-dense system of artifa
