What is the composite pattern and where is it used in real life?

The composite pattern is a structural design pattern that allows you to compose objects into tree structures to represent part-whole hierarchies. It's commonly used in scenarios where you want to treat individual objects and compositions of objects uniformly.

Can you give me some real-world examples of the composite pattern?

Sure! One common example is a graphic design application where shapes like circles, squares, and groups of shapes can be treated as a single object. Another example is a file system where files and directories can be treated uniformly.

How does it differ from other design patterns?

The composite pattern differs from other design patterns like the decorator pattern, which adds behavior to individual objects, while the composite pattern focuses on treating individual objects and compositions uniformly.

What are the benefits of using the composite pattern?

The main benefits include simplifying client code, allowing for easier management of complex tree structures, and promoting flexibility in adding new components.
