Create a class RectangleExample in eclipse. Copy the following code into the class.

RectangleExample.java

package mypackage; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.shape.Rectangle; public class RectangleExample extends Application { Rectangle rect1, rect2; @Override public void start(Stage stage) { Group root = new Group(); //Drawing a Rectangle rect1 = new Rectangle(); //Setting the properties of the rectangle rect1.setX(20.0f); rect1.setY(20.0f); rect1.setWidth(300.0f); rect1.setHeight(10.0f); rect1.setFill(javafx.scene.paint.Color.RED); //Add to a Group object root.getChildren().add(rect1); //Drawing a Rectangle rect2 = new Rectangle(); //Setting the properties of the rectangle rect2.setX(20.0f); rect2.setY(40.0f); rect2.setWidth(200.0f); rect2.setHeight(10.0f); rect2.setFill(javafx.scene.paint.Color.GREEN); //Add to a Group object root.getChildren().add(rect2); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Drawing a Rectangle"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }

If necessary, add package name to accommodate to your eclipse setup.

Run the code to see the output.

Change the length, position, and color of the rectangles to see the effect.
