JavaFX Textfield Examples

Continue your JavaFX Components learning via this tutorial.

Example 1: Textfield

Let us look at the code

Step 1: Create Project

1. Open your favorite Java IDE.
2. In the menu go to File --> Create New Project.

Step 2: Dependencies

No dependencies are needed for this project.

Step 3: Write Code

Our code will comprise the following java files:

• TextFieldExample.java

1. In your editor or IDE, create a file known as TextFieldExample.java.
2. Then add the following code:

(a). TextFieldExample.java

Our class will do with some imports. Let's go ahead and add them:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;

Extend the class as shown below:

public class TextFieldExample extends Application {

Our class will have the following methods:

• void main(String[] args)
• void start(Stage primaryStage)

The starting point of our Java app will be main method which we create as follows:

    public static void main(String[] args) {

In this particular class we will be overriding our void start(Stage primaryStage) method.
Prepend the code>@Override</code modifier to your method. Then add implementation code as follows:

    @Override
    public void start(Stage primaryStage) {
        TextField textField = new TextField();
        textField.setFont(Font.font("Arial", FontWeight.BOLD, 36));

        textField.setText("This text is visible");

        String text = textField.getText();
        System.out.println(text);

        Scene scene = new Scene(new Pane(textField), 500, 250);
        primaryStage.setScene(scene);
        primaryStage.show();

    }

Here is the full code:

package com.jenkov.javafx.textfield;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;

public class TextFieldExample extends Application {

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

    @Override
    public void start(Stage primaryStage) {
        TextField textField = new TextField();
        textField.setFont(Font.font("Arial", FontWeight.BOLD, 36));

        textField.setText("This text is visible");

        String text = textField.getText();
        System.out.println(text);

        Scene scene = new Scene(new Pane(textField), 500, 250);
        primaryStage.setScene(scene);
        primaryStage.show();

    }
}
