JAVA编程训练——Game: playing a TicTacToe game

     In a game of TicTacToe, two players take turns marking an available cell in a 3x3 grid with their respective tokens(either X or O). When one player has placed three tokens in a horizontal, vertical, or diagonal row on the grid, the game is over and that player has won, A draw (no winner) occurs when all the cells on the grid have been filled with token and neither player has achieved a win. Create a program for playing TicTacToe.

    The program prompts two players to enter X token and O token alternately. Whenever a token is entered, the program redisplays the broad on the console and determines the status of the game (win, draw, or continue).
