java - How do I replace an item in an array in an arraylist? -

i have arraylist, initialized follows:

    public static list<int[]> items = new arraylist<int[]>(); 

i add items this:

    items.add(new int[] {2,0,1,0,1}); 

can change specific entry on array on arraylist (for example: 2 @ index 0), or have recreate array every time items.set()?

you can this:

int[] array = items.get(0); array[0] = <new value>;
