字符串反转案例演示
键盘输入字符串,如”abc”
输出结果”cba”

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入一个字符串:");
        String str = scanner.nextLine();
        char[] chars = str.toCharArray();
        String result = "";
        for (int i = chars.length - 1; i >=0; i--) {
            result += chars[i];
        }
        System.out.println(result);
    }
