Hangman Java class: Dictionary (2 of 3)

package org.inksaver.java;
/*
    Hangman console version Java
    You will need all 3 class files:
    Main.java       http://pastebin.com/nbuy3y90
    Hangman.java        http://pastebin.com/chsL0dbY
    Dictionary.java     http://pastebin.com/BKkvSap3
    get dictionary.txt from github or elsewhere call it "dictionary.txt" in same folder as src
    https://github.com/dmcguinness/Hangman/blob/master/dictionary.txt
    The methods used here may not be the most efficient, but have been chosen to
    match as far as possible the code used in the Lua and Python versions,
    so they can be directly compared and contrasted.
