The document outlines key concepts related to the Unified Modeling Language (UML) relevant to the SCJA exam, focusing on UML representations of classes, inheritance, and associations. It emphasizes the importance of understanding various UML diagram types, particularly the class diagram, as part of the exam's requirements. Additionally, it provides specific details on the notation used for attributes and operations in UML.

[<visibility>] <variable_name> [: <type>] [= default_value]
• Operations Compartment :
[<visibility>] <method_name> [<parameter-list>] [: <return-type>]

Chapter 9:Representing Object-Oriented Concepts with UML
- 2. Recognizing Representations of Significant UML Elements • Exam Objective 2.1 Recognize the UML representation of classes, (including attributes and operations, abstract classes, and interfaces), the UML representation of inheritance (both implementation and interface), and the UML representation of class member visibility modifiers (-/private and +/public). 2
- 3. • The SCJA exam requires minimum knowledge of the UML Infrastructure and Superstructure specifications. Of the 14 UML diagram types, the class diagram is the only diagram type on the exam. • There is value in understanding UML diagrams and features that are outside the scope of this exam. • So in your independent research on UML, don’t ignore the other diagram types since this knowledge will surely come in handy later for you at work. 3
