Tic-Tac-Toe Success

I'm so happy I finished my tic-tac-toe project.  Its a simple text based Java app that allows two players to enter coordinates and play a game of ti-tac-toe.  I know its not earth-shattering or really anything super different, but it was pretty difficult for me to complete and took about 2 weeks.  It got easier after I backed up and restarted & I figured out a mistake I was making in passing variables out of methods back to the main method & learned a few new tricks using strings and printf(). 

Even though these are relatively simple programs I've been building, I would like to learn how to deploy them.  

The next project I chose will be working with regex (regular expressions) to write a program that goes through text and determines its readability.  After that I will probably chose the matrix problem.  JetBrains keeps suggesting I start some super-hard problem.  After my pain with tic-tac-toe, I feel like I can take on the medium style problems rather than skipping right to the big super duper problems.  We'll see how this goes.
