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

UML static view-class diagram, object diagram, package diagram, and uml package diagram The most important thing to draw a class chart is to abstract the class and first recall the basic content of the class. I. Category 1. Concep

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
