JavaFX Sphere

Implementation

So, we have seen the functionality of the sphere class. Now, let's see the actual implementation.

The below program creates a sphere with a radius of 50.0. After that, a group object is created to which our sphere is attached. Then the position of the sphere is changed using setTranslationX() and setTranslationsY() methods. Then we set the title for our application. After that, a new scene is created to which our group object is attached then, this scene is attached to the stage. Finally, we call the show method available on the stage to show the output.

• Scene: This class acts as the container for all the scene graphs in our application.
   
• Group: It is a container component which doesn't give its children any particular layout guidelines. Nodes that are child components are all positioned at 0.
   
• Stage: The most basic JavaFX container is the JavaFX Stage class.

Program

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.shape.Sphere;
import javafx.stage.Stage;
import javafx.scene.*;

public class Sphere_Example extends Application {

	public void start(Stage stage) {
		// Creating a sphere
		Sphere sphere = new Sphere(50.0f);

		// Creating a group
		Group group = new Group(sphere);

		// setting the position of sphere 
		sphere.setTranslateX(250);
		sphere.setTranslateY(250);

		// setting the title for our application
		stage.setTitle("Sphere Example");

		// creating a scene
		Scene scene = new Scene(group, 500, 500);

		// setting scene
		stage.setScene(scene);

		stage.show();
	}

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

Run Code

Execution

To execute the above program. You can follow the given steps:

1. Open up the terminal in the same folder where you have saved your source code.

2. Enter the below code and hit enter.
javac --module-path path/to/your/javaFx/modules --add-modules javafx.fxml,javafx.controls filename.java
After you hit enter a new file will automatically be generated namely filename.class

3. Now, enter the below command and hit enter to execute the above program.
java --module-path path/to/your/javaFx/modules --add-modules javafx.fxml,javafx.controls filename.java

4. You have successfully executed the JavaFX program.

Frequently Asked Questions

What are the three components of JavaFX?

Stage, Scene, and Nodes are the three main components of a JavaFX application.
 

What is a stage in JavaFX?

A stage in a JavaFX application is represented by the Stage class in the javafx.stage package. A Scene, which is made up of visual components, is hosted by a Stage in JavaFX. The start(Stage s) 
method of the Application class receives the platform-created primary stage as a parameter.
 

What is a group JavaFX?

A group is a component that serves as a container for the children without applying any special structuring. Every child node or component, in this case, will remain at position 0,0.

Conclusion

In this article, we have extensively discussed the Sphere Class present inside the JavaFX Framework. We have seen different constructors to initialize the sphere object. Also, we have seen different methods available inside the class along with their implementation.
