Tic-Tac-Toe Game (Java)

This program runs the game tic-tac-toe within the console. The players, X and O, take turns placing their character onto the 3x3 grid. When a player successfully makes 3 in a row, either vertically, horizontally, or diagonally, they win. If no winner is decided upon all squares being filled, it is a stalemate.

I'm wondering how efficient this code is. Are there any redundancies, formatting issues, legibility issues, etc.?

TicTacToe.java

package tictactoe;

public class TicTacToe {

    public static void main(String[] args) {
        GameBoard myGame = new GameBoard();
        myGame.displayBoard();

        int counter = 1;

        while (myGame.gameActive() && counter < 10) {
            if (counter % 2 == 0)
                myGame.askPlayer('O');
            else
                myGame.askPlayer('X');
            counter++;

            System.out.println("\n");
            myGame.displayBoard();
            myGame.checkForWinner();

            if (counter == 10 && myGame.gameOnGoing() == true)
                System.out.print("Stalemate!\n");
        }

    }

}

GameBoard.java

package tictactoe;

import java.util.Arrays;
import java.util.Scanner;

public class GameBoard {
    private char[][] gameBoard;
    private boolean gameOnGoing = true;

    //This is the constructor for the GameBoard class.
    public GameBoard() {
        gameBoard = new char[3][3];

        for (int row=0; row  3 || row  3 || col =0 && row =0 && col <=2) {
            if (gameBoard[row][col] != ' ')
                return false;
            else {
                gameBoard[row][col] = player;
                return true;
            }
        }
        else
            return false;
    }   //end of method makeMove

}

Below are just some quick points. I didn't get into the meat of the GameBoard class.

TicTacToe.java

-
You're using a Magic Number here for your counter. This should be extracted as a constant.

-
The stalemate conditional can be placed outside of the while block, as you already know that counter = 10.

-
I would also extract the X and O chars as constants. I'm curious about what will happen when an unexpected char is passed to askPlayer.

-
There's rarely a point in having a \n in a print or println statement. In your finaly line, you can just have System.out.println("Stalemate!");

-
You have all this game logic in a main method, when it should properly encapsulated into its own separate method.

GameBoard.java

-
Minor point, but I wouldn't initialize gameOnGoing to true by default. Rather, I'd have it set after everything was initialized in the constructor.

-
Extract the gameboard size, 3` as a constant.

-
Regarding comments, you should use proper JavaDoc comments for your methods, and there's no need to comment the end of every method. So this,

//This is the constructor for the GameBoard class.
public GameBoard() {
    gameBoard = new char[3][3];
    for (int row=0; row < gameBoard.length; row++) {
       Arrays.fill(gameBoard[row], ' ');
   }
 }   //end of constructor

should be this:

/**
 * This is the constructor for the GameBoard class.
 */
public GameBoard() {
    gameBoard = new char[3][3];

    for (int row=0; row < gameBoard.length; row++) {
        Arrays.fill(gameBoard[row], ' ');
    }
}
