Java List addressing first and last elements

Question

Is there any better way to access the first and last locations on a java list other than

curr.set(curr.size()-1, 10);
curr.get(curr.size()-1);
curr.set(0, 10);
curr.get(0);

Where curr can be assumed to be a list.

Answer 1

If you use LinkedList you can get the last and first elements.

LinkedList<String> linkedList = new LinkedList<>();
linkedList.add("element");

String last = linkedList.getLast();
String first = linkedList.getFirst();

Both operations are constant time, but a NoSuchElementException will be thrown if the list is empty.
