# Class Circle

java.lang.Object
javafx.scene.Node
javafx.scene.shape.Shape
javafx.scene.shape.Circle

All Implemented Interfaces:
  `Styleable`, `EventTarget`

public class Circle extends Shape
The `Circle` class creates a new circle with the specified radius and center location measured in pixels.

Example usage. The following code creates a circle with radius of 50 pixels centered at (100,100).

    import javafx.scene.shape.Circle;

    Circle circle = new Circle();
    circle.setCenterX(100.0f);
    circle.setCenterY(100.0f);
    circle.setRadius(50.0f);

Since:
  JavaFX 2.0
