What is the difference between the Composite Pattern and the Decorator Pattern?

What is the difference between the Composite Pattern and the Decorator Pattern?

The Composite Pattern is used to treat individual objects and compositions uniformly, while the Decorator Pattern adds behavior to individual objects dynamically.

Can you give me an example of each pattern?

Sure! In the Composite Pattern, you might have a graphic system where shapes can be grouped. In the Decorator Pattern, you could have a coffee shop where you can add milk or sugar to a coffee object.

When should I use one pattern over the other?

Use the Composite Pattern when you need to work with tree structures and treat individual and composite objects the same. Use the Decorator Pattern when you want to add responsibilities to objects dynamically.

Are there any drawbacks to using these patterns?

Yes, the Composite Pattern can lead to a complex structure, making it hard to manage. The Decorator Pattern can result in many small classes, which can complicate the system.
