JavaFX PasswordField

However, typing a password in a text field is not secure for the user. The Application must use a specific component to get the password from the user.

Passwordfield can be created by instantiating javafx.scene.control.PasswordField class. PasswordField class contains a method named as setPromptText() for showing a prompt text to the user in password field. The data written in the passwordfield is retrieved by getText() method.

Example:

  package application;  import javafx.application.Application;  import javafx.scene.Scene;  import javafx.scene.control.Button;  import javafx.scene.control.Label;  import javafx.scene.control.PasswordField;  import javafx.scene.control.TextField;  import javafx.scene.layout.GridPane;  import javafx.stage.Stage;  public class PasswordFieldTest extends Application {      public static void main(String[] args) {  launch(args);  }    @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  Label user_id=new Label(“User ID”);  Label password = new Label(“Password”);  TextField tf=new TextField();  PasswordField pf=new PasswordField();  pf.setPromptText(“Enter Password”);  Button b = new Button(“Submit”);  GridPane root = new GridPane();  root.addRow(0, user_id, tf);  root.addRow(1, password, pf);  root.addRow(5, b);  Scene scene=new Scene(root,300,200);  primaryStage.setScene(scene);  primaryStage.setTitle(“PasswordField Example”);  primaryStage.show();  }  }
