Is there a way to see if certain integers are in certain places within an arraylist?

Question

For example, if an arraylist holds the values [1, 2, 3], is there any way to check if they are in that order using indexOf or any other way?

Are you asking if there is a way to check if a list is sorted? — gariepy, Jan 13 '16 at 16:03
No, I am wondering if you can check if an arraylist has certain values in certain places of an array. — Trevor, Jan 13 '16 at 16:15

Just compare the order and the array with a for-loop:

public boolean isArrayInOrder(int[] array, int... order) {
    if(array.length == order.length) {
        for(int i = 0; i < array.length; ++i) {
            if(array[i] != order[i]) return false;
        }
        return true;
    }
    return false;
}
