Problem

Gomoku is a game played by two players on a 19 by 19 board. One player uses black stones and the other player uses white stones. The two players alternate putting down stones on the board with the goal to be the first to get five of their stones in a row either vertically, horizontally, or diagonally. Your task is to make a GUI implementation of this game using JavaFX.

The application shall display the game board. The board shall be tan or beige. The grid shall be black. The game shall allow the two players to alternate placing their stones on the board. The application shall only allow players to place their stones in valid locations. The application shall not allow players to place their stones on stones already on the board. One player's stones shall be black. The other player's stones shall be white. The application shall indicate which player's turn it currently is. The application shall detect horizontal, vertical, and diagonal wins. When a player wins, the five stones in a row shall be highlighted on the board. When a player wins, the application shall indicate who the winner is.
