Printing two strings with same size and similar names but different number at the end

Question

So I am trying to print two strings in the same for loop and here is what i am working at

        ArrayList Arr1 = new ArrayList(15);
        ArrayList Arr2 = new ArrayList(15);

        for(int i=0;i<2;i++)
        for(int y=0;y < Arr(i).size();y++){

            System.out.println(Arr(i).get(y));
        }
