This study guide covers inheritance hierarchies, focusing on the relationships between superclasses and subclasses. It explains type diagrams (or hierarchy trees) as visual representations of these relationships. The guide also introduces polymorphism, demonstrating how subclass objects can have multiple types and its implications for method parameters, arrays, and ArrayLists.
