What information is typically included in the attributes section of a class diagram?

The attributes section of a class diagram specifically details the variables associated with that class. These variables represent the data elements that define the state of the objects created from the class. By including attributes in a class diagram, developers can visualize what properties an object of the class will have, facilitating a better understanding of how the class will function and interact within the system.

While methods, relationships with other classes, and access modifiers are important aspects of a class diagram, they do not belong in the attributes section. Methods represent the behavior of the class and are listed separately, relationships illustrate how classes interact with one another through associations, and access modifiers indicate the visibility of attributes and methods but are not themselves attributes. Thus, focusing on the attributes is essential as they provide crucial information about the data that the class will manage.
