I need help finishing this class??? it is for Java
Class: PlayTicTacToe
The Tic Tac Toe client Application class is the driver program that contains the main method.
The main method will get the names of the players from the user and use those names to instantiate an instance of the TicTacToe class called game.
The main method will have one big loop that will execute as long as the client says “yes” he/she whishes to play another game of tic tac toe.
Inside the loop (every time the game is played):
The game will be initialized
(While the last player to take a turn is not a winner and the players have not taken 9 turns)
- The player is switched (i.e. if the player is PLAYER_X, the player will become PLAYER_O, etc…)
- The player takes A Turn. - number of turns taken is incremented.
The results will be displayed The players will be asked if they wish to play the game again.
