Figure 14-5 . Creating shapes
How It Works
In this solution, you generated some basic 2D shapes. The first shape is a
javafx.scene.shape.CubicCurve class, which allows you to construct a cu-
bic curve (a “squiggly line”) effect. To create a cubic curve, simply look for the appro-
priate constructor to be instantiated. The following code snippet is used to create a
javafx.scene.shape.CubicCurve instance:
CubicCurve cubicCurve = new CubicCurve();
cubicCurve.setStartX(50);
