UML diagram to Java code I am having a hard time with the room and door class to transform it from UML diagram to JAVA CODE. The human class and Thing class does not need to be coded but the room

class and door class needs to be coded. Here is what I have for world class so far, if you think it needs fixing, please fix it:

public class World{ private ArrayList rooms; //constructor public World(){ //arrayList for type Room rooms = new ArrayList(); } public void addRoom(Room room){ //add room object into arrayList room rooms.add(room); } public ArrayList getRooms(){ return room; } public String toString(){ /* *will show info on each room */ String info = ""; for(int i= 0; i

World - rooms: ArrayList + World0 +addRoom(room Room) +getRooms() ArrayList + toString(): String
