Question

4.interface
given below. In the main method also include a simple usage example.
Here are the rules of N x N Tic-Tac-Toe game:
• Players take turns placing characters into empty squares (" ").
• The first player A always places "X" characters, while the second player B always places "O" characters.
• "X" and "O" characters are always placed into empty squares, never on filled ones.
• The game ends when there are N of the same (non-empty) character filling any row, column, or diagonal.
• The game also ends if all squares are non-empty.
• No more moves can be played if the game is over

Must be outputted in the console not with gui.

Interface to be implemented:
public interface TicTacToe
{
/** Starts a new game on a board of size x size.
@return void. */
public void reset (int size);
/** Retrieves either ', 'X' or '0' from the position x and y on the
board.
1
@return Char'', 'X' or '0'.
@throws TicTacToeException ("Invalid coordinates") if values x, y
exceeds board size. */
public Char boardValue (int x, int y);
/** Simulates palyer A move. Player A plays 'X'.
@return 1 if player A won. 0 if this was the last move and the board
is full, thus draw. -1 if the game is not finished.
@throws TicTacToeException ("Invalid coordinates") if values x,y
exceeds board size. TicTacToeException ("Cell is already used") if
the cell at coordinates x,y was already used before */
public int playerAMove (int x, int y);
/** Simulates palyer B move. Player B plays '0'.
@return 1 if player B won. O if this was the last move and the board
is full, thus draw. -1 if the game is not finished.
@throws TicTacToeException ("Invalid coordinates") if values x, y
exceeds board size. TicTacToeException ("Cell is already used") if
the cell at coordinates x,y was already used before */
public int playerBMove (int x, int y);
} // end TicTacToe

Exception class to be used:
public class TicTacToeException extends Exception {
public TicTacToeException (String message) {
super (message);
}
}
