2D ArrayList (Read 1739 times)

2D ArrayList
Oct 26th, 2007, 6:56am  
I've been at this one for a while now.
I've created an initial ArrayList and then I add more ArrayList in it (so it becomes a 2D array). No problem there.

example:
-----------------------------------------------------
ArrayList root = new ArrayList();

ArrayList subArray = new ArrayList();
subArray.add("text01");
subArray.add("text02");

root.add(subArray);
-----------------------------------------------------

So far, so good, No error.
The problem is, when I try to read the data.
-----------------------------------------------------
println(root.get(0)) //returns [text01, text02];
-----------------------------------------------------

Problem there, is I can't access the information after that because it returns an Object.

My question is, is there any way I could access the information in my Object or can I convert my Object to an Array?

Any help would be very appreciated.

You have to cast the object you get into an ArrayList :

Code:
ArrayList array = (ArrayList)root.get(0);
println(array.get(0));
println(array.get(1));
