What are the parameters for a rectangle in the polygon shape class

I want to make a rectangle with the polygon class. I know you can use the rectangle class, but it needs to be made under the polygon class. How can i set paramters to initalize a rectangle. Im using javafx.

        Polygon polygon = new Polygon();
        
        //Adding coordinates to the polygon 
         polygon.getPoints().addAll(new Double[]{ 
         200.0, 50.0, 
         400.0, 50.0, 
         450.0, 250.0,          
         400.0, 250.0, 
         100.0, 250.0,                   
         100.0, 150.0,       
        });

i started with this just as a template, but it makes a pentagon.

Making a rectangle with Polygon instance

From Doc :

a polygon, defined by an array of x,y coordinates. The Polygon class is similar to the Polyline class, except that the Polyline class is not automatically closed.

So , a Polygon is made of 2d xy coordinates where the last 2dpoint make an edge with the first one automatyically closing its shape

In this example a 200*50 pixels rectangle is made like so

rectangle xy

App.java

public class App extends Application {

    @Override
    public void start(Stage stage) {
        Polygon polygon = new Polygon();
        polygon.getPoints().addAll(new Double[]{
            0.0, 0.0,// a
            200.0, 0.0,//b
            200.0, 50.0,//d
            0.0, 50.0 //c   
        });
        polygon.setFill(Color.YELLOWGREEN);
        polygon.setStroke(Color.BLACK);
      
        
        var scene = new Scene(new StackPane(polygon), 640, 480);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }

}

result :
