This is a classic Java serialization question. Option B is definitely the right answer.

I agree with Scot. The readObject method is part of the deserialization process, so it's called after the object is deserialized.

Option B seems to be the correct answer. The readObject method is called after the object is deserialized, not before.

Well, let's think about it. The readObject method is used to deserialize an object, so it makes sense for it to be called after the object is deserialized.

I think the readObject method is called before the object is deserialized.
