}

}

class fin extends lib

First, before going into technical details about a specific language (like Java), you will have to decide what information you want to manage, and perhaps save in a database, about the students. Do you want only simple things like student name, age, sex, telephone? Do you need to record information about every subject for which the student registers, including at least the final grades? Do you want to include payment information?

Depending on how complete the system is going to be, you might easily need 20 or more different tables in a database, and the corresponding windows and other objects to manage the information.
