java - Confused at to why this arraylist code is not working? Includes alist.removeLast(); -


anyone know code does?

i confused, , doesn't work reason though in textbook.

here array list:

   arraylist<integer> alist = new arraylist<integer>();     while(!alist.isempty()){       alist.removelast();   }

the alist.removelast(); piece of code has error in it

im not sure piece of code supposed , how work.

if exact code in textbook, textbook wrong. arraylist.removelast() not exist. however, linkedlist.removelast() exist.

and looks method taking strange approach emptying list.
