How do programming interfaces differ across languages?

Programming interfaces can vary significantly between languages. For example, in Java, interfaces are used to define methods that must be implemented by classes, while in Python, interfaces are more about duck typing and can be implemented using abstract base classes.

Can you give examples of interfaces in Java and Python?

Sure! In Java, an interface might look like this:

public interface Animal {
    void makeSound();
}

In Python, you could use an abstract base class:

from abc import ABC, abstractmethod

class Animal(ABC):
    @abstractmethod
    def make_sound(self):
        pass

What are the advantages of using interfaces?

Interfaces promote a clear contract for classes, enhance code reusability, and allow for polymorphism, making it easier to manage and scale code.

Are there any languages that don't support interfaces?

Yes, some languages like JavaScript do not have a formal interface construct, but they achieve similar functionality through duck typing and object-oriented principles.
