Tic Tac Toe Game (Console Based) in Java full project free download

Game Features

• As the program starts executing, player X starts
• The player types in a column and a row number. For example for column A and row 3, it should be ‘A3’.
• The program should verify that the box is not already populated, if it is already set then the program asks the player to re-enter a new column and a row. If it is not already populated then set that particular box to X.
• Program checks to verify if there is any winner
• The program prints out the Tictactoe board.
• Program asked player O to type in a column and a row number.
• The program should verify that the box is not already populated, if it is already set then the program asks the player to re-enter a new column and a row. If it is not already populated then set that particular box to O.
• Program checks to verify if there is any winner
• The program prints out the Tictactoe board.
• The steps should be repeated until all boxes are populated or a winner is found.
• The program should end.
