What is the difference between the Bridge Pattern and the Adapter Pattern?

What is the difference between the Bridge Pattern and the Adapter Pattern?

The Bridge Pattern is used to separate an abstraction from its implementation, allowing them to vary independently. The Adapter Pattern, on the other hand, is used to allow incompatible interfaces to work together by converting one interface into another.

Can you give me an example of each pattern?

Sure! For the Bridge Pattern, imagine a remote control that can operate different types of devices (like TVs and radios) without being tied to a specific device. For the Adapter Pattern, think of a power adapter that allows a device with a specific plug type to connect to a different type of socket.

When would I use one pattern over the other?

Use the Bridge Pattern when you want to decouple an abstraction from its implementation, especially when both can evolve independently. Use the Adapter Pattern when you need to integrate a new class into an existing system without modifying the existing code.

Are there any drawbacks to using these patterns?

Yes, both patterns can introduce complexity. The Bridge Pattern can lead to a larger number of classes, while the Adapter Pattern can make the system harder to understand if overused.
