how many objects are eligible for garbage collection when end line of main is reached?
===

My main problem is how many object is really created at executing the line
 
    Dozens [] da = new Dozens[3];
And how many object will be eligible for garbage collection at the end of main function

    class Dozens {

    int[] dz = {1,2,3,4,5,6,7,8,9,10,11,12};

    }

    public class Eggs {

    public static void main(String[] args) {

    Dozens [] da = new Dozens[3];

    da[0] = new Dozens();

    Dozens d = new Dozens();

    da[1] = d;

    d = null;

    da[1] = null;

 // do stuff

    }

    }
