What is the difference between the composite pattern and other design patterns?

The composite pattern is a structural design pattern that allows you to compose objects into tree structures to represent part-whole hierarchies. It differs from other patterns like the decorator or strategy patterns, which focus on behavior rather than structure.

Can you give me an example of the composite pattern in use?

Sure! Imagine a graphic application where you have shapes like circles and squares. You can create a composite shape that groups these shapes together, allowing you to treat them as a single object. This way, you can apply transformations to the entire group.

How does the composite pattern compare to the decorator pattern?

The composite pattern is about creating a tree structure of objects, while the decorator pattern is about adding behavior to individual objects dynamically. The composite pattern focuses on the 'whole-part' relationship, whereas the decorator enhances functionality.

Are there any drawbacks to using the composite pattern?

Yes, one drawback is that it can make the design overly complex if not managed properly. It may also lead to performance issues if the tree structure becomes too deep or large.
