The java.util package has an interface called ListIterator that extends the Iterator interface and includes additional methods specific to iterating through the elements of lists forward or backward. Write a class called ArrayListIterator 2 that adds some or all of these methods. The methods to add are as follows (see the Java API Specification for descriptions of each method):

• public void add(E value)
• public boolean hasPrevious()
• public int nextIndex()
• public E previous()
• public int previousIndex()
• public void set(E value)
