Quick study sessions to strengthen memory and retain key concepts.
What role do abstract classes play in inheritance?
Abstract classes define common behavior and enforce a contract for subclasses. An abstract class in Java provides a…
View Card →Why might forced inheritance be a poor design choice?
Forced inheritance can lead to rigid and complex code. If inheritance is used when a 'has-a' relationship is…
View Card →How can visibility affect inheritance in Java?
Visibility controls which class members are accessible to subclasses. In Java, visibility modifiers like 'protected' and 'private' determine…
View Card →What does subclassing mean in Java?
Subclassing is creating a new class based on an existing class. In Java, subclassing is when you create…
View Card →How does the 'is-a' relationship guide inheritance in Java?
The 'is-a' relationship means a subclass should truly be a type of the superclass. In Java, inheritance should…
View Card →Why does interfaces in polymorphism matter in this design?
They define methods for dynamic method resolution. Interfaces in Java allow different classes to be treated through a…
View Card →When should you consider composition over inheritance?
When flexibility and decoupling are needed. Composition involves building complex types by combining objects, offering more flexibility than…
View Card →How does Java handle multiple inheritance with interfaces?
Through interfaces, not class inheritance. Java doesn't support multiple inheritance of classes due to ambiguity issues, but it…
View Card →Why does using 'final' in inheritance change runtime behavior?
Prevents further subclassing or method overriding. In Java, marking a class as `final` means it cannot be subclassed,…
View Card →When is inheritance a good fit?
When the subtype is a real, stable specialized form of the parent type. Inheritance works best when the…
