Help with method getRoom()

[susan]

I have a bunch of room objects. I need a method to return a certain room object based on a String input.

Code:

public Room getRoom(String roomName){
     //code to return the room object with the name roomName
     return room;
}

I also need a way to randomly return a room object.

A room object:
Code:

public Room(String name, String description) {
        this.name = name;
        this.description = description;
        visits = 0;
    }

Thanks

I think in your case, you'd be better off using a HashMap, for problem A anyway. That way you wont have to do an interactive search, and you can mention why you used a hashmap and its advantages over other collections for this particular problem.
Also think about applying generics if you are using Java 5.
