I need to make this program into a tic tac toe game versus the computer instead of user in Javafx. Highlight the winning row too if possible. Thank you.

BorderPane borderPane = new BorderPane(); borderPane.setCenter(pane); borderPane.setBottom(lblStatus); // Create a scene and place it in the stage Scene scene = new Scene(borderPane, 450, 170); primaryStage.setTitle("TicTacToe"); // Set the stage title primaryStage.setScene(scene); // Place the scene in the stage primaryStage.show(); // Display the stage }
