## Class Arc

- java.lang.Object
- - javafx.scene.Node
  - - javafx.scene.shape.Shape
    - - javafx.scene.shape.Arc

- All Implemented Interfaces:
    `Styleable`, `EventTarget`

      public class Arc
      extends Shape

  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);

  Since:
    JavaFX 2.0
