Write a program to play tic-tac-toe with a user at the terminal using java. The user chooses who goes first and can play the game multiple times. The implemented strategy will complete a 2-in-a-row if possible and will otherwise block a user 2-in-a-row. The program recognizes a win by either player and a cat's game situation when it is the computer's turn.

(Please Include Comments within the code explaining each portion and how it works)
