Class ArrayList<E>
E - the element type.public class ArrayList<E> extends AbstractList<E> implements List<E>, Cloneable, RandomAccess, Serializable
This implementation differs from JDK 1.5 ArrayList in terms of
capacity management. There is no speed advantage to pre-allocating array
sizes in JavaScript, so this implementation does not include any of the
capacity and "growth increment" concepts in the standard ArrayList class.
Although ArrayList(int) accepts a value for the initial
capacity of the array, this constructor simply delegates to
ArrayList(). It is only present for compatibility with JDK
1.5's API.
