CodingForums.com - Help Finishing a Program

I'm trying to write a program that creates a tic-tac-toe board using an array and then lets you play it. I need help writing the code that checks if a player has won using a method.
Here is what I have:

Code:

public static char checkForWin(char [][] board){

        char retval = 'F'; // 

        int xCount = 0;

        int oCount = 0;

        

        for(int row = 0; row < board.length; row++){

            for(int col = 0; col < board.length; col++){

                if(board[row][col] == 'X')

                    xCount+= 1;

                else if(board[row][col] == 'O')

                    oCount+= 1;

            }

        }

        

        if(xCount < board.length || oCount < board.length)

            retval = 'N';

        else if(xCount == board.length)

            retval = 'X';

        else if(oCount == board.length)

            retval = 'O';

                    

        return retval;

then where the method is called:

Code:

win = checkForWin(board);

            } while(win == 'N'); // must be F, O or X to leave loop

            if(win == 'F'){

                System.out.printf("\nThe board is Full: no Winner\n");

            } else {

                System.out.printf("\nThe winner is %c\n", win);
