An oft-overlooked access level is "default" (a.k.a. "package-
private"), which is the level when there is no other access keyword
('public', 'protected' or 'private'). This creates package-friendly
access, allowing access (and inheritance) for types in the same
package but not otherwise.

For real fun, consider an inner class that inherits from its
containing type:

 package eg;
 public class Foo
 {
    /* p-p */ void packageFriendly()
    {
        System.out.println( "Foo#packageFriendly()" );
    }

    private void hiddenInside()
    {
        System.out.println( "Foo#hiddenInside()" );
    }

    class InnerFoo extends Foo
    {
        void packageFriendly()
        {
            System.out.println( "InnerFoo#packageFriendly()" );
        }

        private void hiddenInside()
        {
            System.out.println( "InnerFoo#hiddenInside()" );
        }
    }

    public static void main( String[] args )
    {
        Foo foo = new Foo().new InnerFoo();
        foo.packageFriendly();
        foo.hiddenInside();
    }
 }

run:
InnerFoo#packageFriendly()
Foo#hiddenInside()
