    //write your code here......
    int[] adverseArr = new int[arr.length];
    int index = arr.length - 1;
    for (int i = 0; i < adverseArr.length; i++) {
        adverseArr[i] = arr[index];
        index--;
    }

// 把数组arr的值全部替换成数组adverseArr的值。 for (int i = 0; i < arr.length; i++) { arr[i] = adverseArr[i]; }

    System.out.println(Arrays.toString(arr));
