Wait, I thought interfaces were for storing user data. This coding stuff is way over my head.

Don't worry, coding can be complex but with practice, you'll get the hang of it!

Option B and D are correct because they define methods that must be implemented by classes that use the interfaces.

Interfaces in coding are used to define a set of methods that a class must implement.

A and B, easy peasy. Interfaces are like the Highlander - there can be only one abstract method per interface!

C looks good to me. Extending an interface to add more methods makes sense.

I agree, B is correct because it defines two functions without any implementation.

I think A is incorrect because 'abstract' is not a valid keyword for a function in an interface.

D is definitely wrong. Interfaces can't implement other interfaces, they can only extend them.

I think A and B are the correct answers. Interfaces can only have abstract methods, and they can't inherit from concrete classes like Point.
