Question

I am trying to convert a section of code from using an ArrayList of custom objects to a regular array.

Previous my definition was

ArrayList<Room> rooms = new ArrayList<Room>();

Which I have now changed to

Room[] rooms;

Previously I used the below line to add items to the array list

rooms.add(new Room(1,1,30,false,true,true,false));

But I am now struggling to find the way I should simply add individual items to the array throughout code.

I think you are best sticking with an arrayList here, but just to give you a bit more light on it.

To do what you are trying to do, you will have to keep a index integer which will just point to the current position in the array, then when you add you can increment this and add the new object into the next poisition.
When you get to the maximum size of your array, you will need to expand it.
You will find that there has been questions on expanding an array which have been asked already and you can find the answers here:
