Hi Sean, Did you get this sorted out? If not, could you post the full code for Person and the class that uses it (sean?) - including the package & import statements at the top of the class. The error looks really weird - like it thinks that the class is called Person. rather than Person - maybe you compiled it with javac Person..java by mistake? (Though I'm not sure that javac would let you do this). Also, if sean is a class, it should start with a capital letter. Package names should be all lower case.
