Does anybody could give a code for Airport Managment JAVA?

I am student ta one european University. We have Objectorientinted Programming. The organisation of the course is so bad, that is impossible.
It is very hard for me and my friends that we small programming experance have.

Could some one help?

In a few sentences we must to :

We must to organise types of the Persons and Emloyes (abstract) and define Passangeres, Pilots, Steward., destination, orgijg, flight.... We habe also special enums of Passanger Identification (Passport , ID cars...) , enum of Pilot cathegory (captain and coplitot) and we habe types of the Airplanes and we have to connect it with a vectros clases. we habe some list of plane types and we need to implemetn vector to organise the:
Personmanagment, Flightmanagment origing and destinaiton managment.
ans also we have some crew and passngeres.
at the and we habe controller that schould implements all classes.

It to hard to axplain because of that that I dont unterstand it.

I would be really thankful if you could somwthing to help me.
