compile -- permission denied

Hi all,
I was trying to compile my java files and got the message below. I
didn't understand the message, "Permission denied", but I just tried
again as a root. Then, I was able to compile.

I'd like to understand why this happens.
I am using Java 1.5 and Fedora core 4.

-------------------------------------------------
[jonghook@localhost Research]$ javac Main.java
Main.java:18: error while writing Main: Main.class (Permission denied)
public class Main {
^
1 error
[jonghook@localhost Research]$ sudo javac Main.java
Password:
[jonghook@localhost Research]$
----------------------------------------------------

You don't have permission to create files in that directory. You need
to either change the permissions (using chmod as root) or put the result
of the compiler elsewhere (using the -d option to javac).

I don't use that feature often, but could it be that the directory
where the target class files were directed to does not yet exist?

The "error while writing" + "(Permission denied)" bits seem to indicate
that you don't have permission to write to the target file. If the file
already exists, check that you are the owner, and/or that you have write
permission on it. Otherwise, check that you are the owner of the current
directory and/or you have permission to create new files in it.

Thank you. You're exactly right. I already had compiled files and
those were compiled as a root. So I deleted all those files and
compiled again as a user. In that way, I was able to run the program.

Thank you very much, everyone.
