java中怎么将一个字符数组反序

Question

新手java中怎么将一个字符数组反序，不要new数组，只能使用一个字符数组，三克油

可以用Collection.reverse(list)呀，先把你的数组放到List里，再Collection.reverse(list)，然后再从list中拿回来，示例代码：

public static void main(String[] args) {
        String[] deal = new String[3];
        deal[0] = "0";
        deal[1] = "1";
        deal[2] = "2";
        List<String> list = new ArrayList<String>();
        for (int i = 0; i < deal.length; i++) {
            list.add(i, deal[i]);
        }
        Collections.reverse(list);
        for (int i = 0; i < list.size(); i++) {
            deal[i] = list.get(i);
        }
        for (int i = 0; i < deal.length; i++) {
            System.out.println(deal[i]);
        }

    }
