Classpath problem

Question

i am here stuck..
my dir structure is
c:\my\xxx\yyy\zzz
i have a code ...
package xxx.yyy.zzz;
class A
// some code
}i have compiled sucessfully and put the clsss file into c:\my\xxx\yyy\zzz folder.
now i want to import it in another class
like...
package xxx.yyy; // note this
import xxx.yyy.zzz.*; // note this
class B
// some code
// creating instance of class A here
}question is how do i compile and run it ?
i am at c:\my---> what should be the command to compile and run the above code?
plz give me the explicit command so that i can test and verify . i have given the dir structure.
i have tried several ways but got class not found exception and errors . i know its a classpath problem but i could not figure out what should i type at the c:\my prompt.
can u give exact command to run and compile the above code in steps ?
thanx

question is how do i compile and run it ?You don't with that code. You've defined class A to have "package visibility," meaning it can't be used from outside its package. You should declare it with public visibility instead, like "public class A {...".
Once you change that, use these commands to compile and run:c:\my\>javac xxx/yyy/zzz/A.java
c:\my\>javac xxx/yyy/B.java
c:\my\>java xxx.yyy.B
