Package Problem, Please Help...

[Marius BONG]

i write 2 two java application (in separate file)
one is called SubclassB.java and another one is SuperclassA.java
-----------------------------------------------

SuperclassA.java
package packageA;
public class SuperclassA
{
public int superclassVarA;
public void superclassMethodA( )
{
}
}
class SubclassA extends SuperclassA
{
void subclassMethodA( )
{
superclassVarA = 10;
}
}
class AnyClassA
{
SuperclassA obj = new SuperclassA( );
void anyClassMethodA( )
{
obj.superclassMethodA( );
}
}
---------------------------------------------
//SubclassB.java
package packageB;
import packageA.*;
public class SubclassB extends SuperclassA
{
void subclassMethodB()
{
superclassMethodA();
}
}
class AnyClassB
{
SuperclassA obj = new SuperclassA( );
void anyClassMethodB( )
{
obj.superclassVarA = 20;
}
}

when i compile the SuperclassA.java, no problem. But when i compile SubclassB.java this errors come up:
C:\My Documents\Java\SubclassB.java:3: package packageA does not exist
import packageA.*;

if the packageA is in folder say "thecode"
and your making packageB in that folder,you got to import thecode.packageA.*;
ie. always go up one level if your in another package within abig package(folder)
hope i'm right

Make sure that your directory
C:\My Documents\Java
is in the classpath.
Then, when you say that SuperclassA is in package packageA, you have to make sure that it IS. You are promising the compiler that there is a subdirectory under the classpath with the given package name.
So SuperclassA.class needs to reside in
C:\My Documents\Java\packageA\SuperclassA.class
- unless of course you have it jarred up, in which case the jar file that contains that subdirectory needs to be in the classpath directory.
