使用Pair访问Map中的值

Question

    import java.util.HashMap;
    import java.util.Iterator;
    import java.util.Map;

    import org.javatuples.Pair;

    public class Graph {
        /*Map for memorizing the hallways and the rooms*/
        public static HashMap<Vertices,Pair<Room,Room>> House = new HashMap<Vertices,Pair<Room,Room>>(200);          

        public static void main(String[] args) throws NullPointerException {            

            Room r1 = new Room (1,"room");
            Room r2 = new Room (2,"room");
            Room r3 = new Room (3,"room");
            Room r4 = new Room (4,"room");

            Room h1 = new Room (5,"hallway");
            Vertices v1_1 = new Vertices (1,2);
            Vertices v1_2 = new Vertices (1,5);

            Vertices v2 = new Vertices (2,5);
            Vertices v3 = new Vertices (3,5);
            Vertices v4 = new Vertices (4,5);           

            r1.setDoorNumber(2);
            System.out.println(r1.doorNumber);

            for (int i = 0; i<r1.doorNumber; i++) {
                Door d = new Door("room");

                r1.Doors.add(d);
            }   

            r2.setDoorNumber(2);
            for (int i = 0; i<r2.doorNumber; i++) {
                Door d = new Door("room");
                r1.Doors.add(d);
            }
            r3.setDoorNumber(1);
            for (int i = 0; i<r3.doorNumber; i++) {
                Door d = new Door("room");
                r1.Doors.add(d);
            }
            r4.setDoorNumber(1);
            for (int i = 0; i<r4.doorNumber; i++) {
                Door d = new Door("room");
                r1.Doors.add(d);
            }

            House.put(v1_1, Pair.with(r1, r2));
            House.put(v1_2, Pair.with(r1, h1));     
            House.put(v2, Pair.with(r2, h1));
            House.put(v3, Pair.with(r3, h1));
            House.put(v4, Pair.with(r4, h1));



            for (Map.Entry<Vertices,Pair<Room,Room>> entry: House.entrySet())
            {
                Vertices key = entry.getKey();
                Pair<Room, Room> value = entry.getValue();

                System.out.println(key.firstLabel + " " + key.secondLabel);
                System.out.println(value.getValue(0) + " " + value.getValue(1)); //

            }

        }

    }

我尝试制作一个代表建筑物的项目。我试过这个，但是我无法得到我的对的实际价值（我得到了房间@ 17327b6房间@ 14ae5a5输出，但我需要像1对的房间 - “房间”等等意味着来自Pair的对象类的价值）
