The document contains Java code for a Tic Tac Toe game, including a main class and a TicTacToe class. The main class handles player input for names and markers, manages turns, and checks for winners or ties while enabling players to continue playing. The TicTacToe class manages the game state, including the game board and rules, while handling player markers and win conditions.
