ArrayList is a List, where u can store any objects.
List list = new ArrayList();
If you just want int or String in it, you have to use Generics.
List<String> list = new ArrayList<String>();
If you want to store data in it, use the add() method.
list.add("test");
An ArrayList stores objects in your save order, so list[0] is your first added data, list[1] your second, etc.
Your 'Tile Map editor':
Use buttons (squares) and each time you click on a button (square), add your data to your list.
List list = new ArrayList();
