JavaFX: Working with Label widget

Label is used to display non-editable text in the user interface.

How to create Label?

Label class provides below constructors to define label widget.

public Label()

public Label(String text)

public Label(String text, Node graphic)

Ex

Label label1 = new Label();

label1.setText("Hello JavaFX");

Label label2 = new Label("Good Morning");

InputStream is = new FileInputStream(imageFilePath);

Image image = new Image(is);

Label label3 = new Label("Java Icon", new ImageView(image));

Find the below working application.

LabelApp.java

package com.sample.demos;

import static javafx.geometry.Pos.CENTER;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class LabelApp extends Application {

 private static String imageFilePath = "C:\\Users\\krishna\\Documents\\Study\\javaFX\\javaIcon.png";

 @Override
 public void start(Stage primaryStage) throws FileNotFoundException {

  Label label1 = new Label();
  label1.setText("Hello JavaFX");

  Label label2 = new Label("Good Morning");

  InputStream is = new FileInputStream(imageFilePath);
  Image image = new Image(is);
  Label label3 = new Label("Java Icon", new ImageView(image));

  VBox vBox = new VBox(10, label1, label2, label3);
  vBox.setAlignment(CENTER);

  Scene scene = new Scene(vBox, 600, 600);

  /* Set the scene to primaryStage, and call the show method */
  primaryStage.setTitle("JavaFX Label Example");
  primaryStage.setScene(scene);
  primaryStage.show();
 }

}

TestFx.java

package com.sample.demos;

import javafx.application.Application;

public class TestFX {
 public static void main(String args[]) {
  Application.launch(LabelApp.class, args);
 }
}

When you ran above application, you can able to see below window.
