javac compile error

Question

Hi.

Trying to create a test app that imports another test package.

The test apps are listed, as is the compile cmd and the err..

The files are all in the same dir. I was able to compile the MyIncorrectnessListener.java, and the MycssErrorHandler.java with no warnings/errs.

I'm trying to figure out what's the cause of the err >>> sjsu_classes.java:33: '.' expected <<<<<

Any pointers/comments are appreciated...

thanks

the compile cmd/err

[root@toshiba parseapp2]# javac -Xlint -classpath '/opt/htmlunit/lib/
*:/parseapp2/' sjsu_classes.java sjsu_classes.java:33: '.' expected
import MyIncorrectnessListener;
                             ^
sjsu_classes.java:33: ';' expected 
import MyIncorrectnessListener;
                              ^
sjsu_classes.java:34: class, interface, or enum expected 
import MycssErrorHandler;
      ^

3 errors
3 warnings

Your java files have to be in a directory that matches their package names, so you have to place MyIncorrectnessListener.java in a directory named MyIncorrectnessListener, MycssErrorHandler.java in a directory named MycssErrorHandler and so on.

You could place them all in the same directory, but you have to remove the 'package' statement in the files.

The error you're getting is because you're only giving a package name in the import statement. You should import something specific, or everything, from a package. Change it to

import MyIncorrectnessListener.MyIncorrectnessListener;

or

import MyIncorrectnessListener.*;

Or if you don't place your files in any packages, you don't need any import statements.
