The stroke property specifies/defines the color of the boundary of a shape. You can set the color of the boundary using the setStroke() method of the javafx.scene.shape.Shape class.
This method accepts a Color value as a parameter and sets the given color to the boundary of a shape.
By default, the value of this property for the shapes (objects) line, path and polyline is null and, for all the remaining shapes the default value of this property is Color.BLACK.

//Creating a Group object
