当我在编译的时候出现的一个问题．
E:\jpp>javac LotteryOdds.java
LotteryOdds.java:10: cannot find symbol
symbol  : method nextIn()
location: class java.util.Scanner
        int n = in.nextIn();
                  ^
1 error

这个应该怎么样解决啊？
我的环境变量设置为：
classPath
.;E:\java\JDK\lib\dt.jar;E:\java\JDK\lib\tools.jar;


程序源码为：

import java.util.*;

public class LotteryOdds
{
    public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);

        System.out.print("How many numbers do yow need to draw?");
        int n = in.nextIn();

        int lotteryOdds = 1;
        for(int i=1;i<=n;i++){
            lotteryOdds = lotteryOdds * (n-i+1)/i;
        }
        System.out.println("Your odds are 1 in "+lotteryOdds+" Good Luck!");
    }
}
