Take Three - Java IO and Sorting

EDIT- 
Jan 21, 2012 
It was brought to my attention that there are libraries to implement different sorting algorithms.
I've decided NOT to reinvent the wheel (though I do intend to learn wheel-crafting in case I am ever in a jam).

C++ version of assignment :

• HERE 
• Tested with THIS text file
• OUTPUT
• Can sort by word count or alphabetical order  

NOTE:
Works on my machine, but compiling on trucks/moons doesn't work (doesn't recognize 'strtok' - scope issue? Perhaps there is an alternative? )

TAKE THREE DRAFT:
So far, Version 3 on its way... Plus a few thoughts:

• realized I forgot to print a file with the other versions. (Fixed it)
• What's better?
• sorting as you add data 
• sorting after you've added all data
• What about functors? 
• make different functors for different algorithms?
• switch functors and compare times? 

How can I add color.... hmmm.....
