> I am using Windows XP. In my system, CLASSPATH is set to "E:\workspace
> \pkg\src". Initially, the file is present in the folder "E:\workspace
> \pkg\src\". When I tried to compile it, there was no error. But when I
> tried to execute the command,
>
> java haaa.hello
>
> then it returned an error like this:-
>
> Exception in thread "main" java.lang.NoClassDefFoundError: haaa/hello

> Caused by: java.lang.ClassNotFoundException: haaa.hello
> at java.net.URLClassLoader$1.run(Unknown Source)
> at java.security.AccessController.doPrivileged(Native Method)

> Also, my system has a Linux OS. In Linux OS, whenever I compile and

> I try to compile in terminal using javac command then it tells that
> "no such command found". For setting PATH variable in Linux, I need to
