Array list returns null

In a class (State):

Code :

---

 
	private int[][] array = board.startArray();
 
 
	public int[][] getArray() {
		return array;
	}
 
I use the arrayList fine in the rest of the code (startArray works).

---

In another class

Code :

---

State game;
int[][] testArray = game.getArray();

---

Why does the arrayList return null? Im sure I have used this before.

Thanks

Looks like the object (of type State) hasn't been initialized.

If you are certain you are initializing it, you may want to check over to see if you are waiting for user input or something similar. In a past program I created, I found an object wasn't being initialized because it was waiting for user input. Hope this helps.

And by the way, it looks like you are working with arrays here, not an array list. They are quite different as an array list is dynamic (can grow and shrink) and an array is of fixed size.

Sorry, i have used arraylists so much lately i forgot i used an array there.

Thanks, i will check and see what i get
