Trouble grouping objects into a list
Hello, I'm working on this program for school and I'm a bit stumped. To the point:
In a class that is known as mazeLevel which basicly creates "Room" objects, which map out the game's level using a HashMap by assigning exit key values to each room. I need to make an array list of the fields (just a list of Room variables) in the mazeLevel class. I need to be able to get an array list of rooms out of any *Level class that I may put in the game there for make a method outside the mazeLevel class.
Could anyone give me some idea of how I could do this? Do you need more information?
Would this be possible to do with a for:each loop or is there some other way, thanks. :)

I'd create a 2 dimensional array to hold those Room objects:
int rows = 7, columns = 10;
Room[][] map = new Room[rows][columns];
for(int r = 0; r < rows; r++) {
for(int c = 0; c < columns; c++) {
String value = (char)(c+'a')+""+(r+1);
System.out.println("Creating: Room("+value+")");
map[r][c] = new Room(value);
}
}
