working directory要改为哪里？最好举个简单的例子

c:\sample\A.java的内容如下：
package sample;
class A{
public static void main(String[] args){
System.out.println("hello world");
}
}

查看目录：
C:\>dir sample
Volume in drive C is OS
Volume Serial Number is 94D2-727F

Directory of C:\sample

06/25/2009 10:32 PM <DIR> .
06/25/2009 10:32 PM <DIR> ..
06/25/2009 10:32 PM 108 A.java
1 File(s) 108 bytes
2 Dir(s) 36,781,862,912 bytes free

编译A.java
C:\>javac sample\A.java

再次查看目录，多了A.class
C:\>dir sample
Volume in drive C is OS
Volume Serial Number is 94D2-727F

Directory of C:\sample

06/25/2009 10:34 PM <DIR> .
06/25/2009 10:34 PM <DIR> ..
06/25/2009 10:34 PM 414 A.class
