Question

Method signatures are included in which diagram?

1) Activity diagram
2) Package diagram
3) Class diagram
4) Design class diagram

Answer 1

Method signatures are included in Class diagrams and Design class diagrams, which show the static structure of a system including classes and their relationships.

Step-by-step explanation:

Method signatures are typically included in a Class diagram or a Design class diagram. In UML (Unified Modeling Language), a Class diagram displays the static structure of a system, including classes, their attributes, operations (or methods), and the relationships between the classes. The signature of a method, which includes the method name, its parameters, and return type, is represented within the class compartments of these diagrams. On the other hand, Activity diagrams and Package diagrams do not typically show method signatures as their purpose is to represent workflow or package organization, respectively.
