hi,

I am making a game in Java FX but I have completed the connect 4 games. I need help with making that into Java model view controller which I don't know hows that work. Please help me with creating MVC. Please help me, I spend so much time to figured it out.

here is my working code:

import javafx.application.Application; import javafx.geometry.Insets; import javafx.geometry.Pos; import javafx.scene.layout.*; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.stage.Stage; public class ConnectFour extends Application { //declaring an instance variables  int columns = 7; int rows = 6; private char playerTurn='p'; private Cell[][] cell = new Cell[rows][columns]; @Override public void start(Stage primaryStage) throws Exception { //creating an GirdPane  GridPane gridPane = new GridPane(); for (int i = 0; i < 6; i++) for (int j = 0; j < 7; j++) gridPane.add(cell[i][j] = new Cell(i,j), j, i); //creating an border pan to display the connect-four game  BorderPane borderPane = new BorderPane(); HBox bottomPane = new HBox(); bottomPane.setAlignment(Pos.CENTER); bottomPane.setPadding(new Insets(20)); borderPane.setBottom(bottomPane); borderPane.setCenter(gridPane); //setting the size for the consule  Scene scene = new Scene(borderPane, 750, 750); scene.setFill(Color.GREEN); primaryStage.setTitle("Exercise16_31"); primaryStage.setScene(scene); primaryStage.setResizable(true); primaryStage.show(); } //now all thses function going to check all circle  public boolean isWon(char occurrence) { for (int p = 0; p < 6; p++) if (cell[p][0].getOcc() == occurrence && cell[p][1].getOcc() == occurrence && cell[p][2].getOcc() == occurrence && cell[p][3].getOcc() == occurrence) { cell[p][0].setFlashCircles(occurrence); cell[p][1].setFlashCircles(occurrence);
