public class Main {
    public static void main(String[] args) {
        int[] arr = new int[6];
        Scanner scanner = new Scanner(System.in);
        for (int i = 0; i < arr.length; i++) {
            arr[i] = scanner.nextInt();
        }
        System.out.println(Arrays.toString(arr));

        //write your code here......
	   //把数组先复制到一个新的数组newArr
        int[] newArr=new int[6];
        for (int i = 0; i < arr.length; i++) {
            newArr[i]=arr[i];
        }
	  //然后将数组newArr的值倒着遍历赋给arr就ok了
        int i=0;
        for(int j=arr.length-1;j>=0;j--){
            arr[i]=newArr[j];

        }
