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.

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).

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.

• Operations Compartment :
