Wait, what if we just make the whole thing abstract? That might do the trick. Option A could be the way to go here.

I disagree with Blondell, I believe changing Line 2 to an abstract method is more important.

Haha, imagine if we just made the whole thing extend AutoCloseable. That would be a wild move, but I kinda like option D.

Ah, I see. We can't have an interface with a method body, so we'll need to change Line 2 to an abstract method. Option E looks like the way to go.

I think we also need to change Line 2 access modifier to protected.

Hmm, I think we need to change Line 1 to make this class compile. I'm leaning towards option C, making it a regular class.
