ArrayList?

[Jon Camilleri]

What's wrong here?

...
ArrayList<Integer> magicNumbersList = new ArrayList<Integer>();
	for (int x = 0; x < 10; x++)
	{
		for (int y = 0; y < 10; y++)
		{
			Integer anInteger = Integer.valueOf(magicNumbers[x][y]);
			magicNumbersList.add(anInteger);
			if (y == 9)
				{
					System.out.println();
				}
		}
	}

	for (int i = 0; i < magicNumbersList.size(); i++)
	{
		System.out.println(magicNumbersList.get(i));
	}
...

If you want to get the item you just added, you can do this:

System.out.println(magicNumbersList.get(magicNumbersList.size()-1)); //what do I get?

Do you have an import statement for ArrayList at the top of your program?
