Hi
I am really new to JAVA. I've created an ArrayList<String> and want to
sort

1. <application, algorithm> To arrange a collection of items
	in some specified order.  The items - {records} in a file or
	data structures in memory - consist of one or more {fields} or
	members.  One of these fields is designated as the "sort key"
	which means the records will be ordered according to the value
	of that field.  Sometimes a sequence of key fields is
	specified such that if all earlier keys are equal then the
	later keys will be compared.  Within each field some ordering
	is imposed, e.g. ascending or descending numerical, {lexical
	ordering}, or date.

	Sorting is the subject of a great deal of study since it is a
	common operation which can consume a lot of computer time.
	There are many well-known sorting {algorithms} with different
	time and space behaviour and programming {complexity}.

	Examples are {quicksort}, {insertion sort}, {bubble sort},
	{heap sort}, and {tree sort}.  These employ many different
	data structures to store sorted data, such as {arrays},
	{linked lists}, and {binary trees}.

	2. <tool> The {Unix} utility program for sorting lines of
	files.

	{Unix manual page}: sort(1).

the elements. I tried using toArray(), but I cannot grok

/grok/, /grohk/ (From the novel "Stranger in a Strange Land",
	by Robert A. Heinlein, where it is a Martian word meaning
	literally "to drink" and metaphorically "to be one with")

	1. To understand, usually in a global sense.  Connotes
	intimate and exhaustive knowledge.

	Contrast {zen}, which is similar supernal understanding
	experienced as a single brief flash.  See also {glark}.

	2. Used of programs, may connote merely sufficient
	understanding.  "Almost all C compilers grok the "void" type
	these days."

the docs I
found at
http://JAVA.sun.com/j2se/1.4.2/docs/api/JAVA/util/ArrayList.html#toArray()

This seems like it should be trivial but I am just not 'getting it'

TIA

See Collections.sort(List);

Awesome thanks :)
