The Arc class represents a 2D arc object, defined by a center point, start angle (in degrees), angular extent (length of the arc in degrees), and an arc type (ArcType#OPEN, ArcType#CHORD, or ArcType#ROUND).

Example usage: the following code creates an Arc which is centered around 50,50, has a radius of 25 and extends from the angle 45 to the angle 315 (270 degrees long), and is round. 

import javafx.scene.shape.*;

Arc arc = new Arc();
arc.setCenterX(50.0f);
arc.setCenterY(50.0f);
arc.setRadiusX(25.0f);
arc.setRadiusY(25.0f);
arc.setStartAngle(45.0f);
arc.setLength(270.0f);
arc.setType(ArcType.ROUND);
