Advanced Java Concepts: Inheritance, Method Overriding, and UML Diagrams for CPSC 233

This tutorial for CPSC 233 (Winter 2013) focuses on advanced Java programming concepts, emphasizing inheritance, method overriding versus method overloading, and the role of static members. It incorporates practical exercises using UML diagrams to clarify the relationships and functionalities within class hierarchies. Participants will analyze source code to identify inherited data members and methods, as well as recognize method overrides and overloads. Additionally, a review and quiz section will help reinforce understanding of these key concepts.
