在corejava这本书的原码中，有用到Console类的用例v1ch3/lotteryodds的地方
我按书上写的设置：set classpath=.;c:/corejava
但编译lotteryodds.class时，还是提示Console类路径问题
我把带有console.java的目录corejava 拷贝到lotteryodds.java的目录下就没有问题，
不晓的set classpath应怎样设置？？

编译时必须让所有药用的java所在的路径都在classpath里

我设过了，
我的autoexec.bat如下：
path =d:/JBuilder6/jdk1.3.1/bin
set classpath=e:/download/corejava //这里有问题吗？？
set classpath=d:/JBuilder6/jdk1.3.1/lib
set classpath=.;d:/JBuilder6/jdk1.3.1/dt.jar;d:/JBuilder6/jdk1.3.1/tools.jar

set classpath=.;d:/JBuilder6/jdk1.3.1/dt.jar;d:/JBuilder6/jdk1.3.1/tools.jar
为什么是=.: ? 中间有个小点

Set path =d:/JBuilder6/jdk1.3.1/bin
set classpath=e:/download/corejava
set classpath=d:/JBuilder6/jdk1.3.1/lib;%classpath%
set classpath=.;d:/JBuilder6/jdk1.3.1/dt.jar;d:/JBuilder6/jdk1.3.1/tools.jar;%classpath%

"为什么是=.: ? 中间有个小点"
这不是当前目录吗？

to强人：
不是第一句的问题 Set path =d:/JBuilder6/jdk1.3.1/bin
我编译都能找到javac

果然如此，怪不得我每次执行时都要加上 -classpath . Xxx
现在classpath中加入 .;就可不用加-classpath执行了.

目录结构是：
c:/corejavabook
c:/corejavabook/corejava/console.java
c:/corejavabook/v1ch2/
c:/corejavabook/v1ch3/LotteryOdds/LotteryOdds.java
其中LotteryOdds.java中
/**
* @version 1.00 07 Feb 1996
* @author Cay Horstmann
*/
import corejava.*;
public class LotteryOdds
{ public static long lotteryOdds(int high, int number)
{ long r = 1;
int i;
for (i = 1;
i <= number;
i++)
{ r = r * high / i;
high--;
}
return r;
}

public static void main(String[] args)
{ int numbers = Console.readInt
("How many numbersdo
you need to draw?");
int topNumber = Console.readInt
("What is the highest number you can draw?");
long oddsAre = lotteryOdds(topNumber, numbers);

System.out.println
("Your odds are 1 in " + oddsAre + ". Good luck!");
}
}

再加上/jre/rt.jar试试
set classpath=.;d:/JBuilder6/jdk1.3.1/dt.jar;d:/JBuilder6/jdk1.3.1/tools.jar ;
d:/JBuilder6/jdk1.3.1/jre/lib/rt.jar

还是不起作用！连编译也同不过，
import corejava.*是引入的corejava.jpr包吗，本人刚学，实在不懂？
