数据量不大:
| Scanner sc = new Scanner(System.in); |
| int a = sc.nextInt(); |
| char op = sc.nextLine().charAt(0); |
如果比较大可以换:
| Scanner sc = new Scanner(new BufferedInputStream(System.in)) |
不嫌麻烦可以写:
| public class Main { |
| |
| static BufferedReader cin = new BufferedReader(new InputStreamReader(System.in)); |
| static PrintWriter cout = new PrintWriter(new OutputStreamWriter(System.out)); |
| |
| public static void main(String[] args) throws IOException { |
| int a = Integer.parseInt(cin.readLine()); |
| cout.println(a); |
| |
| cout.flush(); |
| cout.println(a); |
| cout.flush(); |
| } |
| } |
