Class Diagram UML的组成 根据目的分类 类之间的关系 Generalization,一般化 UML的组成 UML共有14个图、7个结构图和7个行为图。 结构图的目的是根据系统概念、关系等来表示元素,并查看每个元素的静态一面, 而动作图的目的是查看每个元素的变化、流动、数据进出等行为,类图对应于结构图。 类图是显示类内静态内容或...
Example:In a class diagram, you might represent classes like “Car,”“Engine,” and “Wheel,” showing their attributes and methods, as well as relationships like “Car has an Engine” and “Car has Wheels.” Object Diagram: Purpose:Object diagrams, on the other hand, focus on capturing ...

The following diagram shows an object diagram with its defining class diagram inset, and it illustrates the way in which an object diagram may be used to test the multiplicities of assignments in class diagrams. The car class has a 1-to-many multiplicity to the wheel class, but if a 1-to...
Object is an instance of a class in a particular moment in runtime that can have its own state and data values. Likewise a static UML object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time, thus an object diagram...

In UML, object diagrams provide a snapshot of the instances in a system and the relationships between the instances. By instantiating the model elements in a class diagram, you can explore the behavior of a system at a point in time.
