Lists

• In addition to the standard collection methods, the List interface allows for random access of elements through its get and set methods.
• List indices are zero based, so list.get(list.size())) is not a valid element.

  	List stuff = new ArrayList();
  
  	stuff.add("Apple");
  	stuff.add("Orange");
  
  	// what's the last item? Indexes are zero based!
  	System.out.println(stuff.get(stuff.size() - 1));
  
  	// change the first item to a pear.  
  	stuff.set(0, "Pear");
  
  	// now iterate
  	Iterator it = stuff.iterator();
  
  	while(it.hasNext())
  	{
  		String item = (String)it.next();
  		System.out.println(item);
  	}
  

• ListIterator allows element addition, removal, and replacement during iteration.
• The java.util package provides two new List implementations: ArrayList and LinkedList.
• Vector is a legacy class retrofitted to the new Collection framework, and is thread safe.
