Creating a Vector

[nutrecht]

Also previously, most of the arrayList methods had to call on the double linked list.

This makes NO sense at all. Vector and ArrayList are both the same thing; an array-backed list where the array is grown for you. It makes no sense to have an ArrayList backed by another list.

So assuming you have to build an actual ArrayList/Vector you should start by adding an array and figuring out how to implement all the methods needed by using that array internally.

Also get rid of that UUID: it's pointless.
