What are the differences between mixins and interfaces in programming?

What are the differences between mixins and interfaces in programming?

Mixins are a way to add functionality to classes by including methods from other classes, while interfaces define a contract that classes must follow without providing implementation.

Can you give me an example of how to use a mixin?

Sure! In Python, you can create a mixin class with methods and then inherit from it in your main class to add those methods.

What about interfaces? How do they work?

Interfaces in languages like Java define methods that a class must implement, ensuring a certain structure without dictating how the methods should work.

Are there any advantages to using mixins over interfaces?

Yes, mixins allow for code reuse and can provide default implementations, while interfaces focus on defining a contract without implementation.

Can you summarize when to use each?

Use mixins when you want to share behavior across classes, and use interfaces when you want to enforce a contract for class behavior.
