I'm confused because the VampirePersister in the example is a class that implements serializable. Instead of using serializable , you wanted us to make it an interface so that BinaryMonsterPersister can implement from MosnterPersister?

The idea here is that you can create the interface and implement it in different ways. The assignment requires you to implement it one way, using binary file I/O. In other circumstances you might implement the interface it some other way, for example using text I/O.
