Notice that we didn’t need to override a method and implement it for us to be able to serialize a Person object. This is because Serializable is a marker interface.

A better start would be to tell me what an interface is, before telling me about a particular type of interface

The course is really good and I highly recommend it. However, be aware that some important aspects are not covered and they expect you to know them beforehand, such as interfaces. Also, throughout all Java modules there are some other fundamental principles which are not really discussed, such as abstraction.
