java generics syntax arrays

what information structure does following chapter specify?

 list<arraylist>[] myarray;

i cruise should announce an array where any component list (e.g., linkedlist an arraylist) need any list enclose arraylist objects.

my reasoning:

 list<string> somelist;             // list twine objects
 list<arraylist> somelist;         // list arraylist objects
 list<arraylist>[] somelistarray;  // an array list arraylist objects

after controlling tests, i dynamic accepts an array where any component an linkedlist vigilant does mention linkedlist objects contain.

so list<arraylist> specifies list contingency contain, nonetheless list<arraylist>[] specifies list contingency implemented.

am i blank something?

here tests.

import java.util.arraylist;
import java.util.list;
import java.util.linkedlist;
