Java - File Output

In order to do this,  you will need to write an output method in the back end classes for all of the UI windows you creating that allow the user to enter data. Specifically, the following backend classes will need an output method:

Faculty

Student

BaseClass

Classroom

Select 1 of the output methods - .PrintWriter or XML Formatted Output

Make sure that whatever methods you choose, you write out all the data in the class, including any lists, even if there is no data in the lists, they should be part of the output in the event that there is data in a list.

Although it's not necessary to create data objects to store the data, I would like to see data persistence done via the back end classes.

Any help clearing compile errors would be appreciated.
