Scoping Java objects - using package protected scope to ensure abstractions don't bleed out

AwesomeSauce.java

package com.lolz;

public class AwesomeSauce {

    {
        // Note that the interface is package protected so trying to access these outside the
        // package is no-bueno!
        Foo.Bar bar = new Foo.Bar();
        Foo.Baz baz = new Foo.Baz();

        //THIS is the weird syntax I was talking about - "declaring 'new' off of an instance"
        Foo.Bar.BarBazzer1 bazzer1 = bar.new BarBazzer1();
        Foo.Bar.BarBazzer2 bazzer2 = bar.new BarBazzer2();
    }
}

Foo.java

package com.lolz;

//Package level interface within Foo.java - This will provide package only access to the 
// classes defined within the interface

interface Foo {
  
    class Baz {
        public void doTheBaz() {

        }
    }

    class Bar {

        class BarBazzer1 {
            void doTheBazzer() {

            }
        }

        class BarBazzer2 {
            void doTheBazzer() {
            }
        }
    }
}
