What is the difference between composition and decorator patterns?
An example of an AI chatbot conversation about composition vs decorator design patterns.
What is the difference between composition and decorator patterns?
Composition is a design principle where objects are composed of other objects, while the decorator pattern adds behavior to objects dynamically.
Can you give me an example of each?
Sure! In composition, you might have a 'Car' class that is composed of 'Engine' and 'Wheel' classes. In the decorator pattern, you could have a 'Coffee' class and a 'MilkDecorator' that adds milk to the coffee.
When should I use one over the other?
Use composition when you want to create complex types by combining simpler ones. Use decorators when you want to add responsibilities to objects without modifying their structure.
