What is the difference between the decorator and adapter patterns?

What is the difference between the decorator and adapter patterns?

The decorator pattern adds behavior to objects dynamically, while the adapter pattern allows incompatible interfaces to work together.

Can you give me an example of the decorator pattern?

Sure! Imagine a coffee shop where you can add milk, sugar, or whipped cream to your coffee. Each addition is a decorator that enhances the coffee's functionality.

And what about the adapter pattern?

An example of the adapter pattern is a power adapter that allows a device with a specific plug type to connect to a different power outlet.

When should I use each pattern?

Use the decorator pattern when you want to add responsibilities to objects without modifying their structure. Use the adapter pattern when you need to integrate incompatible interfaces.
