Folks,
Thanks for all your help on getting two classes that depend upon
each other to compile; I've finally gotten things to work. Seems I had
a combination of import stupidity (my own) coupled with CLASSPATH misadventures.
Except ...
I was under the impression that the default access modifier was protected.
In java.awt.Container:
Container() {
}
So, Container() should be protected, meaning that it can only be accessed
by classes in the same package OR subclasses in a different package, correct?
I've got this:
trilby >> cat foo/A.java
package foo;
import java.awt.Container;
class A extends Container {
B b = null;
}
When I try and compile A.java:
trilby >> javac foo/A.java
foo/A.java:5: No constructor matching Container() found in class java.awt.Container.
class A extends Container {
^
1 error
If I change Container's default constructor access modifier to protected
explicitly:
// In Container.java:
protected Container() {
}
and then recompile Container.java, I get:
trilby >> javac foo/A.java
trilby >>
What's the deal? Is protected not the default access modifier?
I'm using the BETA release on Solaris 2.4, BTW.
