Draw ArrayList of Path on canvas

This example implement a ArrayList of Path, to store Paths. Then draw on canvas using GraphicsContext.

package javafxdrawpatharray;

import java.util.ArrayList;
import java.util.List;
import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.LineTo;
import javafx.scene.shape.MoveTo;
import javafx.scene.shape.Path;
import javafx.scene.shape.PathElement;
import javafx.stage.Stage;

Use functional operation version:
