Quick study sessions to strengthen memory and retain key concepts.
How does Java support multiple inheritance?
Java supports multiple inheritance through interfaces. Java avoids the complexity of multiple inheritance by allowing a class to…
View Card →Why does deep inheritance hierarchies matter in practice?
They can become difficult to manage and extend. Deep inheritance hierarchies increase complexity, making it hard to understand…
View Card →Why is 'favor composition over inheritance' a common design advice?
It promotes more flexible and maintainable code structures. Favoring composition over inheritance helps avoid the pitfalls of rigid…
View Card →How does polymorphism relate to inheritance?
Polymorphism allows objects to be treated as instances of their parent class. Polymorphism enables methods to be invoked…
View Card →What are design tradeoffs of using inheritance?
Inheritance allows code reuse but can lead to inflexible and complex hierarchies. While inheritance promotes code reuse, it…
View Card →How does inheritance impact flexibility?
Inheritance can reduce flexibility by tightly coupling subclasses to parent classes. Inheritance creates a strong coupling between a…
View Card →Why might you prefer composition over inheritance in Java?
Composition offers greater flexibility and reduces tight coupling. Composition is preferred because it allows changing parts of a…
View Card →What is composition in Java?
Composition is a design principle where a class is composed of one or more objects from other classes.…
View Card →What is reuse by collaboration?
Using composition to achieve code reuse by collaborating objects. Reuse by collaboration involves using objects together to achieve…
View Card →Can a class extend multiple classes in Java?
No, Java does not support multiple inheritance for classes. Java restricts a class to extend only one superclass…
