My NullTest.java contains:
package forpackagetest;
public class NullTest {
final int c[] = {1,2};
final int d[] = {1,2};
//c = null;
}
class abc {
}
class def {
}
My thisisatest.java contains:
import forpackagetest.*;
public class thisisatest {
public static void main ( String args[])
{
NullTest var = new NullTest();
}
}
I do not understand why am I getting the error. Could you help ?
Package structure and directory structure must match.
package forpackagetest;
means that the files mus be:
forpackagetest\NullTest.java
forpackagetest\NullTest.class
So u r saying that I should create forpackagetest folder under C:\Java
Files manually.
Yes.
Then what would be the use of :
C:\Java Files>javac -d . NullTest.java
command ?
You will use the same command down on the forpackagetest folder !
This does not make sense to me because I thought that -d option can
create the package subdirectory for you and to instantiate a class
object you only needed the .class files (I am instantiating NullTest
object in thisisatest ).
I forgot that.
So:
javac NullTest.java
or
javac -d .. NullTest.java
down in that dir.

I started off with :
C:\Java Files> dir
Volume in drive C has no label.
Volume Serial Number is 2EB8-82AA
Directory of C:\Java Files
08/03/2008 04:45 PM <DIR> .
08/03/2008 04:45 PM <DIR> ..
08/03/2008 11:40 AM 180 NullTest.java
08/03/2008 12:30 PM 144 thisisatest.java
2 File(s) 324 bytes
2 Dir(s) 30,197,694,464 bytes free
Then I did:
C:\Java Files>javac -d . NullTest.java
which led to :
C:\Java Files>dir
Volume in drive C has no label.
Volume Serial Number is 2EB8-82AA
Directory of C:\Java Files
08/03/2008 04:48 PM <DIR> .

And

Volume in drive C has no label.

Now this gives error:
