An exercise asks you to use basic objects of type Rectangle
, Polygon
, Elipse
... I used cycles for
but only part of the board appears correct. I leave the code below:

import javafx.stage.*;
import javafx.scene.shape.*;
import javafx.embed.swing.*;

import javafx.scene.text.*;
import java.util.*;
import javafx.scene.paint.Color;
