By using this program:

import javafx.application.*;

import javafx.scene.*;

import javafx.stage.*;

import javafx.scene.layout.*;

import javafx.scene.control.*;

import javafx.event.*;

import javafx.geometry.*;

public class TextFieldDemo extends Application {

TextField tf;

Label response;

Button btnGetText;

public static void main(String[] args) {

launch(args);

}

public void start(Stage myStage) {

myStage.setTitle("TextField Demo");

FlowPane rootNode = new FlowPane(10,10);

// Center the controls in the scene

rootNode.setAlignment(Pos.CENTER);

// Create a scene

Scene myScene = new Scene(rootNode, 230, 140);

// Set the scene on the stage.

myStage.setScene(myScene);

// Create a label that will display the string

response = new Label("You entered: ");

// Create a button that gets the text.

btnGetText = new Button("Get String");

// Create a text field

tf = new TextField();

// Set the prompt

tf.setPromptText("Enter a String");

// Set the preferred column count

tf.setPrefColumnCount(15);

// when ENTER is pressed

tf.setOnAction(new EventHandler() {

public void handle(ActionEvent ae) {

response.setText("You entered: " + tf.getText());

}

});

// get text when button is pressed

btnGetText.setOnAction(new EventHandler() {

public void handle(ActionEvent ae) {

response.setText("You entered: " + tf.getText());

}

});

// Use a separator to better organize the layout.

Separator separator = new Separator();

separator.setPrefWidth(200);

// Add controls to the scene graph.

rootNode.getChildren().addAll(tf, btnGetText, separator, response);

// Show the stage and its scene.

myStage.show();

}

}
