You could implement this using an array:

class Room {
    private Room[] exits = new Room[4];
}

In this example, exits[0] could contain a reference to the room to the north, exits[1] the room to the east, and so on. If an element contains null then that might represent no exit in that direction.

Note that you can create nonlinear data structures using this method, such as A -> B -> C -> A.
