arraylist reverse in arraylist in java

1ArrayList<Integer> arrlist = new ArrayList<Integer>();
2//This is how to reverse arrlist's oringinal order.
3Collections.reverse(arrlist);
4
5//This is how to sort in a reverse order
6 Collections.sort(arrlist, Collections.reverseOrder());

4        for(int i = 1; i < 6; i++){ // bu element index degil.
5            list.add(i);

10            int each = list.get(i);  // unboxing

1I want to store them in another ArrayList
2        ArrayList<Integer>list1 = new ArrayList<>();
3        for(int a = 1; a < 8; a++){
4            list1.add(a);
5}
6   System.out.println(list1); // [1, 2, 3, 4, 5, 6, 7]
7
8ArrayList<Integer>reverse = new ArrayList<>(); //reversleri bunun icine ekledik
9  for (int a = list1.size()-1; a >= 0; a--) {
10 // int each = list1.get(a);  // unboxing altaki ile ayni
11      reverse.add(list1.get(a));
12}
13System.out.println(reverse); // [7, 6, 5, 4, 3, 2, 1]
