Object List (help please)

Question

Hey, I was wondering how I could add objects to an array list as they are created. I have a class that consists of a method that creates "Room" objects and as each one is created I need to add it to an array list:
public static void createRooms()
        Room
                            a1,b1,c1,d1,e1,f1,g1,h1,i1,j1,
                            a2,b2,c2,d2,e2,f2,g2,h2,i2,j2,
                            a3,b3,c3,d3,e3,f3,g3,h3,i3,j3,
                            a4,b4,c4,d4,e4,f4,g4,h4,i4,j4,
                            a5,b5,c5,d5,e5,f5,g5,h5,i5,j5,
                            a6,b6,c6,d6,e6,f6,g6,h6,i6,j6,
                            a7,b7,c7,d7,e7,f7,g7,h7,i7,j7;
        a1=new Room("a1");
        a2=new Room("a2");
        a3=new Room("a3");
        a4=new Room("a4");
        a5=new Room("a5");
        a6=new Room("a6");
        a7=new Room("a7");
        b1=new Room("b1");
        b2=new Room("b2");
        b3=new Room("b3");
//etc.....
//and the room class:
public class Room
    private String description;
    private HashMap<String, Room> exits;
    public static Room currentRoom;
    public ArrayList roomList = new ArrayList();
    public Random numGEN = new Random();
    public Room(String description)
        this.description = description;
        exits = new HashMap<String, Room>();
        roomList.add(this);
    }What I need is for each room object's name to be added into the array list as a room object, so, roomList(0) = a1, roomList(1) = a2, etc...
Thanks

I already know how to
do arrays and array listsBased on this, I am included to disagree:
Room
                            a1,b1,c1,d1,e1,f1,g1,h1,i1,j1,
                            a2,b2,c2,d2,e2,f2,g2,h2,i2,j2,
                            a3,b3,c3,d3,e3,f3,g3,h3,i3,j3,
                            a4,b4,c4,d4,e4,f4,g4,h4,i4,j4,
                            a5,b5,c5,d5,e5,f5,g5,h5,i5,j5,
                            a6,b6,c6,d6,e6,f6,g6,h6,i6,j6,
                            a7,b7,c7,d7,e7,f7,g7,h7,i7,j7;
        a1=new Room("a1");
        a2=new Room("a2");
        a3=new Room("a3");
        a4=new Room("a4");
        ... etc. ...
