解题思路:

注意事项:

参考代码:

Scanner sc = new Scanner(System.in);

int[] arr = new int[10];

for (int i = 0; i < arr.length; i++) {

arr[i] = sc.nextInt();

}

for (int i = 0,j = arr.length - 1; i < j; i++,j--) {

int temp = arr[i];

arr[i] = arr[j];

arr[j] = temp;

}

for (int i = 0; i < arr.length; i++) {

System.out.print(arr[i] + " ");

}
