以下是我的程序，基本上都是仿照Ｆ＆Ｑ里面的
public class Main
{
    public static void main (String args[]) throws Exception
    {
        BufferedReader in = 
            new BufferedReader(
                new InputStreamReader(System.in));

        String in_line = in.readLine();
        StringTokenizer st = new StringTokenizer(in_line);
        int a = Integer.parseInt(st.nextToken());
        int b = Integer.parseInt(st.nextToken());
        if(a<0||b>10)
        System.out.println("Input error");
        else System.out.println(a+b);
    }
}

但是结果是Compile Error
而且有５处无法编译，
C:\temp\361829\Main.java:5: cannot find symbol
symbol  : class BufferedReader
location: class Main
        BufferedReader in = 
        ^

location: class Main
            new BufferedReader(

symbol  : class InputStreamReader
location: class Main
                new InputStreamReader(System.in));
                    ^
C:\temp\361829\Main.java:10: cannot find symbol
symbol  : class StringTokenizer
location: class Main
        StringTokenizer st = new StringTokenizer(in_line);
        ^

symbol  : class StringTokenizer
location: class Main
        StringTokenizer st = new StringTokenizer(in_line);
                                 ^
5 errors

真不明白什么回事，哪位兄弟用java过了此题的，能否借我参考？ＱＱ：33025498
