Example of using getSuperclass()

The getSuperclass() method returns the Class representing the superclass of the entity (class, interface, primitive type or void) represented by this Class. If this Class represents either the Object class, an interface, a primitive type, or void, then null is returned. If this object represents an array class then the Class object representing the Object class is returned.

This example list the superclasses of a class.


package javagetsuperclass;

/**

 * @web http://java-buddy.blogspot.com/
 */
public class JavaGetSuperClass {

    public static void main(String[] args) {

        JavaGetSuperClass me = new JavaGetSuperClass();
        me.doSomething();
        
        SubJavaGetSuperClass subMe = new SubJavaGetSuperClass();
        subMe.doSomething();
        
        Class testClass = javafx.scene.chart.AreaChart.class;
        printClassInfo(testClass);
    }

    public void doSomething(){
        printClassInfo(this.getClass());
    }
    
    static private void printClassInfo(Class someClass){

        StringBuilder info = new StringBuilder();
        
        info.append("someClass: ").append(someClass).append("\n");
        
        do{
            someClass = someClass.getSuperclass();
            info.append("superClass: ").append(someClass).append("\n");
        }while(someClass != null);
        
        info.append("=====").append("\n");
        System.out.println(info);
    }

Google Translate (with tts) on JavaFX, using java-google-translate-text-to-speech

JavaFX Choice Box example

JavaFX Choice Box is UI controls that provide support for quickly selecting between a few options, something like spinner.


Example code: 
package javafxchoicebox;

import javafx.application.Application;
import javafx.beans.value.ObservableValue;
import javafx.collections.FXCollections;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ChoiceBox;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

/**
 *
 * @web http://java-buddy.blogspot.com/
 */
public class JavaFXChoiceBox extends Application {
    
    @Override
    public void start(Stage primaryStage) {
        
        Label label1 = new Label();
        Label label2 = new Label();
        
        ChoiceBox choiceBox = new ChoiceBox(
            FXCollections.observableArrayList(
                "java-buddy", "Java", "Buddy")
        );
        choiceBox.getSelectionModel().selectFirst();
        choiceBox.getSelectionModel().selectedItemProperty()
            .addListener((ObservableValue observable, 
                    Object oldValue, Object newValue) -> {
                label1.setText((String)newValue);
        });
        
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        btn.setOnAction((ActionEvent event) -> {
            String selected = choiceBox.getSelectionModel()
                    .getSelectedItem().toString();
            label2.setText("Hello " + selected);
        });
        
        VBox root = new VBox();
        root.getChildren().addAll(choiceBox, btn, label1, label2);
        
        Scene scene = new Scene(root, 300, 250);
        
        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
    
}
