JAVA PROJECT!!

I need help writing a project proposal for a Java Program. I'm open to better ideas, but I'm looking to write a program that does the generic procedure of choosing a school schedule. For example, the student needs to have a semester schedule where he/she would look for classes (Science, Math, English), then look for the different professors that teach the class and then look for the available sections (times when the class is being taught). I should be able to get 10 fields between the available courses, amount of professors and sections available. My main classes could be schedule, school classes, professors and available sections.

So far, that's all I have in mind. Here are the instructions to follow for the first part of the project...

For this deliverable, you are to detail the type of application you want to create. You will create this project proposal in a word document. This word document should detail what the app will do. This document should be a minimum of 300 words in length. The word document should detail the following information related to the application you intend on creating:

Purpose of the app

Classes you expect you will need for this app. You should detail a minimum of three classes.

Relationship of these classes (ex. parent class, child class, etc.)

Fields these classes will contain (minimum of 10 total fields)

You are to create a complete Java application. This application must be approved by your instructor; however, you will decide what this application is about. This application must include at a minimum:

• Three classes minimum
• At least one class must use inheritance
• At least one class must be abstract
• JavaFX front end as you will see, JavaFX will allow you to create a GUI user interface.
• The User Interface must respond to events.
• If your application requires a data backend, you can choose to use a database or to use text files.

Error handling - The application should be able to handle invalid data
