What are interfaces and why are they important in programming?
Interfaces define a contract for classes, ensuring they implement specific methods. They're crucial for polymorphism.
Can you show me how to implement an interface in Java?
Sure! In Java, you define an interface using the 'interface' keyword, then implement it in a class using 'implements'.
What about in Python? How do I implement interfaces there?
Python uses abstract base classes (ABCs) to define interfaces. You can use the 'abc' module to create them.
Are there any languages that don't support interfaces?
Yes, some languages like JavaScript don't have a formal interface concept, but you can achieve similar behavior using duck typing.
