In general, an arc is a small segment of a curve. In JavaFX it is represented by the javafx.scene.shape.Arc class. This class contains six properties they are −
centerX − This property represents the x coordinate of the center of the arc. You can set the value to this property using the setCenterX() method.
centerY − This property represents the y coordinate of the center of the arc. You can set the value to this property using the setCenterY() method.
radiusX − This property represents the width of the full ellipse of which the current arc is a part of. You can set the value to this property using the setRadiusX() method.
radiusY − This property represents the height of the full ellipse of which the current arc is a part of. You can set the value to this property using the setRadiusY() method.
startAngle − This property represents the starting angle of the arc in degrees. You can set the value to this property using the setStartAngle() method.
length − This property represents the angular extent of the arc in degrees. You can set the value to this property using the setLength() method.
To create a circle you need to −
Instantiate this class.
Set the required properties using the setter methods or, bypassing them as arguments to the constructor.
Add the created node (shape) to the Group object.
