Note: This can be a pair programming activity or done independently.

This homework will provide you with some more practice on creating abstract classes, subclasses, and interfaces. You need to design an app that manages a school. The school has Classrooms, and the Classrooms have Teachers and Students assigned to them. Each classroom contains students in a single grade (1st, 2nd, 3rd, etc.).

The actions and properties of each class is up to you to decide.

• At least one abstract class
• At least one interface
• At least 3 subclasses
• Each subclass must be unique from the others

Bonus:

• Add extra classes/subclasses/interfaces

Java code for classes/interface(s) that meet the requirements above.
