What are some examples of interfaces in code?

Interfaces in code define a contract for classes. For example, in Java, you might have an interface called 'Vehicle' with methods like 'start()' and 'stop()'.

Can you give me a specific example in Java?

Sure! Here's a simple example:

interface Vehicle {
    void start();
    void stop();
}

class Car implements Vehicle {
    public void start() {
        System.out.println("Car started.");
    }
    public void stop() {
        System.out.println("Car stopped.");
    }
}

What about interfaces in Python?

In Python, we use abstract base classes to create interfaces. Here's an example:

from abc import ABC, abstractmethod

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

class Dog(Animal):
    def sound(self):
        return "Bark"
