What are various 2D shapes provided by JavaFX?

JavaObject Oriented ProgrammingProgramming

Following are various geometrical shapes that you can draw using JavaFX

• Line − A line is a geometrical structure joining two-point. The javafx.scene.shape.The line class represents a line in the XY plane.

• Rectangle − A rectangle is a four-sided polygon that has two pairs of parallel and concurrent sides with all interior angles as right angles. The javafx.scene.The Rectangle class represents a rectangle in the XY plane.

• Circle − A circle is a line forming a closed loop, every point on which is a fixed distance from a center point. The javafx.scene.The Circle class represents a circle in the XY plane.

• Ellipse − An ellipse is defined by two points, each called a focus. If any point on the ellipse is taken, the sum of the distances to the focus points is constant. The javafx.scene.Ellipse's class represents an ellipse in the XY plane.

• Polygon − A closed shape formed by a number of coplanar line segments connected end to end is known as a polygon. The javafx.scene.Polygon class represents a polygon in the XY plane.

• Polyline − A polyline is the same as a polygon except that a polyline is not closed in the end. Or, a continuous line composed of one or more line segments. The javafx.scene.Polyline class represents a polyline in the XY plane.

• Cubic Curve − A cubic curve is a Bezier parametric curve in the XY plane is a curve of degree 3. The javafx.scene.CubicCurve class represents a cubic curve in the XY plane.

• QuadCurve − A quadratic curve is a Bezier parametric curve in the XY plane is a curve of degree 2. The javafx.scene.QuadCurve class represents a quad curve in the XY plane.

• Arc − An arc is part of a curve. The javafx.scene.Arc class represents an arc in the XY plane.

To create a required shape you need to −

• Instantiate the respective class.

• Set its properties.

• Add the created object to Group.

//Drawing a Rectangle
Rectangle rect = new Rectangle(150, 30, 100, 65);
//Drawing an ellipse
Ellipse ellipse = new Ellipse(330, 60, 60, 35);
//Drawing Polygon
Polygon poly = new Polygon(410, 60, 430, 30, 470, 30, 490, 60, 470, 100, 430, 100 );
//Drawing a Line
Line line = new Line(540, 30, 540, 90);
line.setStrokeWidth(5.0);
//Drawing a Poly line
Polyline polyLine = new Polyline(25, 210, 100, 210, 50, 180, 50, 230);
polyLine.setStrokeWidth(5.0);
//Drawing a cubic curve
CubicCurve cubicCurve = new CubicCurve(150.0, 210.0, 200.0, 70.0, 200.0, 290.0, 270.0, 210.0);
