cannot find symbol

Hi

I have a very basic problem, I think, I am crazy?

There are two files:

public class Z{}

public class Y extends Z {}

These two files are saved in the same folder. I can not compile the file called Y.java.

This is the message:

cannot find symbol
symbol class Z
public class Y extends Z {}

What is wrong?

You haven't given enough details.

Do the two files have package declarations? In which case you might only be able to compile them in the order Z--->Y. Try that.

They do not have package declarations. It is very basic.

Z.java
Y.java

The source code is writen above. It is really a stupid problem, but I need to understand it.

are the files both named correctly? is your CLASSPATH set?

show us your actual code,
show us the actual error message,

use code tags!

There are two files saved in the same folder:

Z.java:
public class Z{}

Y.java:
public class Y extends Z {}

That is all. I can compile the file Z.java. But I can not compile the file Y.java. I get the following message:

cannot find symbol
symbol class Z
public class Y extends Z {}

Is the folder where Z.class is generated in the CLASSPATH? If you have
"." in the classpath, you should be able to compile from the folder where Z.class is present.

I have saved both files on the desktop. I added CLASSPATH in the environment variable.

C:\Dokumente und Einstellungen\Urs W�fler\Desktop

This is saved in CLASSPATH.

But it does not work. I do not properly understand CLASSPATH.

cd C:\Dokumente und Einstellungen\Urs W�fler\Desktop
javac -classpath . Y.java

Hi,
Do one thing, First after compiling z.java..search it class file where it got generated...compiler is not able to find out that file..!!

It worked.

javac -classpath . Y.java

This was the solution. Thank you.

That's great!
