Class AddWords


public class AddWords
extends Object

This class is used to control the adding of new words to the word list. It accepts input from stdin (typically the keyboard). If a word is at least three characters long it attempts to insert it into the word list. If the word already exists nothing happens, otherwise it is added to the list. If a word of two or fewer characters is entered, then the current word list is saved to a file.
