* backed by a sequential-access store, such as a linked list. For random
* access data, use AbstractList. This class implements the random access
* methods (<code>get</code>, <code>set</code>, <code>add</code>, and
* <code>remove</code>) atop the list iterator, opposite of AbstractList's
* approach of implementing the iterator atop random access.
* <p>
*
* To implement a list, you need an implementation for <code>size()</code>
* and <code>listIterator</code>. With just <code>hasNext</code>,
* <code>next</code>, <code>hasPrevious</code>, <code>previous</code>,
* <code>nextIndex</code>, and <code>previousIndex</code>, you have an
* unmodifiable list. For a modifiable one, add <code>set</code>, and for
* a variable-size list, add <code>add</code> and <code>remove</code>.
* <p>
*
* The programmer should provide a no-argument constructor, and one that
* accepts another Collection, as recommended by the Collection interface.
* Unfortunately, there is no way to enforce this in Java.
