Java - remove last known item from ArrayList

Question

OK, so here is my ArrayList:

private List clients = new ArrayList();

and here is what I am

Answer 1

It should be:

ClientThread hey = clients.get(clients.size() - 1);
clients.remove(hey);

Or you can do

clients.remove(clients.size() - 1);

The minus ones are because size() returns the number of elements, but the ArrayList's first element's index is 0 and not 1.
