Named Vs Unnamed Packages

[Sudhanshu Mishra]

Hi all,
I have a little doubt regarding two codes:

file Bclasse.java
package BBB;
class Bclasse extends Aclasse
{
public static void main(String...a)
{
}
}

File Aclasse.java
public class Aclasse
{
public static void main(String...a)
{
System.out.println("printed in class A");
}
}


Now as you can see that the two codes are in separate files,why is Bclasse unable to access Aclasse even if Aclasse is public.Is it because Aclasse is in unnamed package and Bclasse is in a named package?How does that makes a difference?


Thanks....

Though the class is public, since it's in different package, you have to import it. But for importing the class, you have to specify the fully qualified class name with the package name. So you have no chance of importing classes in default package and using it in a class that belongs to a named package.
