通过Scanner类，获取键盘的输入

        var sc = new Scanner(System.in);
       // while (sc.hasNext())
       //     System.out.println("key context : " + sc.next());
       // 
        //while (sc.hasNextLong())
        //    System.out.println("key context : " + sc.nextLong());
        //
        while (sc.hasNextLine())
            System.out.println("key context : " + sc.nextLine());
