Can I use the inner class of one containing class by the other class

Question

Can I use the inner class of one containing class by the other class in the same package as the containing class
eg I have a class BST which has inner class Enumerator. Can I use the inner class from the other class in the same pacckage as BST?

Answer 1

Inner classes do not share the namespace of the package of the containing class. Also they are never visible to other classes in the same package.Believe what you want, then, if you're going to make up your own rules about how Java works. For people interested in how Java actually works, here is an example that shows why that assertion is false:
package com.yawmark.jdc;
public class Outer {
     public class Inner {
}And...
package com.yawmark.demo;
import com.yawmark.jdc.*;
public class Demo {
     public static void main(String[] args) {
          assert new Outer().new Inner() != null;
}~
