Renaming things is just good practice, not refactoring.

Wait, really? I thought that could be part of it.

I feel like extracting interfaces is a gray area, but I think it still counts as refactoring. Changing external APIs seems like the odd one out here.

I'm not entirely sure, but I think reordering method parameters might be considered refactoring since it improves readability?

I remember practicing a question where we had to identify refactoring techniques, and I feel like extracting methods and renaming things are definitely part of it.

I think refactoring is all about improving code without changing its behavior, so maybe changing external interfaces or APIs isn't refactoring?

Ah, I think I've got it. Changing external interfaces or APIs would be a more significant change than just refactoring, so that's the answer I'm going with.

I'm a bit confused on this one. Reordering method parameters and extracting interfaces both seem like they could be considered refactoring, but I'm not 100% sure.

Extracting methods and renaming things to be more logical both sound like textbook refactoring techniques to me. I'm not sure about the other options.

Changing external interfaces or APIs seems like it would be more than just refactoring, so I'm going to go with that as the answer.

Hmm, this is a tricky one. I'll need to think carefully about the definition of refactoring to figure this out.

Refactoring, huh? I guess that's what they call it when you're just rearranging the deck chairs on the Titanic.

Changing external interfaces or APIs? That's like doing open-heart surgery on your codebase. Not exactly what I'd call a 'refactor'.

Extracting methods and interfaces - those are classic refactoring techniques to improve code organization and flexibility. Can't go wrong with those choices!
