Can you explain what class composition is in programming?
Sure! Class composition is a design principle where a class is composed of one or more objects from other classes, allowing for code reuse and flexibility.
How does it differ from inheritance?
Inheritance creates a parent-child relationship, while composition allows for building complex types by combining simpler ones without a strict hierarchy.
Can you give me an example of class composition?
Absolutely! For instance, if you have a Car
class, it can be composed of Engine
and Wheel
classes, allowing you to create different types of cars with various engines and wheels.
What are the advantages of using class composition?
Class composition promotes code reusability, easier maintenance, and greater flexibility in changing behaviors without altering existing code.
