Very Simple Question

Posted by John Lee on November 16, 2000 at 5:56 PM

//DirectAccess.java
package mylib;

class DirectAccess {
public Integer var = new Integer(10);
}

------------------------------------------------------

//IndirectAccess.java
package mylib;

public class IndirectAccess {
public DirectAccess obj= new DirectAccess();
}

------------------------------------------------------

//client.java
import mylib.*;

class client {
public static void main(String arg[]) {
IndirectAccess ia = new IndirectAccess();
System.out.println(ia.obj.var);
}
}

------------------------------------------------------

compile client.java, got complaint:

client.java:6: The type mylib.DirectAccess to which the member var belongs is
not accessible from class client.
System.out.println(ia.obj.var);
^
1 error

MY QUESTION IS:

in class DirectAccess: wheather var is public or default doesn't make any difference, why wouldn't compiler
complain about this, because if there is no way for any class outside mylib package to access "var", then
its modifier "public" only cause confusion.

Thanks,
John
