Can anyone help me use Bridge design pattern to develop a School Management System [closed]

Use Bridge design pattern to develop a School Management System. The requirements:

• Unlike Student, Teacher shall be able to add a new homework. • Unlike Teacher, Student shall be able to submit a solution. • Unlike Local Person, Foreigner shall be able to request for a dormitory. • Unlike Foreigner, Local Person shall be able to request for loan.

When the program starts, let the main class create four different kinds of users: a local teacher, a foreign teacher, a local student and a foreign student. You will be asked to demo to show how each of these users can use the functionalities listed above.
