How to retrieve the contents of a text field in JavaFX?

The text field accepts and displays the text. In the latest versions of JavaFX, it accepts only a single line. In JavaFX the javafx.scene.control.TextField class represents the text field, this class inherits the javafx.scene.control.TextInputControl (base class of all the text controls) class. Using this you can accept input from the user and read it to your application.

To create a text field you need to instantiate this class, to the constructor of this class. It inherits a property named text from its superclass TextInputControl. This property holds the contents of the current text field. You can retrieve this data using the getText() method.

Example

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class TextFieldGettingData extends Application {
   public void start(Stage stage) {
      //Creating nodes
      TextField textField1 = new TextField();
      TextField textField2 = new TextField();
      Button button = new Button("Submit");
      button.setTranslateX(250);
      button.setTranslateY(75);
      //Creating labels
      Label label1 = new Label("Name: ");
      Label label2 = new Label("Email: ");
      //Setting the message with read data
      Text text = new Text("");
      //Setting font to the label
      Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 10);
      text.setFont(font);
      text.setTranslateX(15);
      text.setTranslateY(125);
      text.setFill(Color.BROWN);
      text.maxWidth(580);
      text.setWrappingWidth(580);
      //Displaying the message
      button.setOnAction(e -> {
         //Retrieving data
         String name = textField1.getText();
         String email = textField2.getText();
         text.setText("Hello "+name+"Welcome to Tutorialspoint. From now, we will
         communicate with you at "+email);
      });
      //Adding labels for nodes
      HBox box = new HBox(5);
      box.setPadding(new Insets(25, 5 , 5, 50));
      box.getChildren().addAll(label1, textField1, label2, textField2);
      Group root = new Group(box, button, text);
      //Setting the stage
      Scene scene = new Scene(root, 595, 150, Color.BEIGE);
      stage.setTitle("Text Field Example");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
