public static void main(String[] args) throws IOException {
		List<Integer> list = addnum();
		System.out.println("输入：");
		// 方法一：强大的Scanner类
		 Scanner sc = new Scanner(System.in);
		 System.out.println("输入的是:" + sc.next());
		// 方法二：
		// BufferedReader br = new BufferedReader(new
		// InputStreamReader(System.in));
		// System.out.println(br.readLine());
		// 方法三：
//		char i = (char) System.in.read();
//		System.out.println(i);
