title: How to close a java window with a button click - JavaFX Project
body: <p>I made a JavaFX project and created the GUI for the first-login frame in the java Scene Builder. When the login is successful, the login frame must be closed and the next frame must be visible (main program frame). I can make the new frame appear, but I can't make the login frame closed. I tried stuff like <code>dispose()</code> but nothing works. Below is the code for the main class:</p>
  
  <pre><code>public class KuberComm extends Application {
  
      @Override
      public void start(Stage stage) throws Exception {
          Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
  
          Scene scene = new Scene(root);
          stage.setResizable(false);
          stage.setTitle("Login to KuberComm");
          stage.setScene(scene);
  
          stage.show();
      }
  
      /**
       * @param args the command line arguments
       */
      public static void main(String[] args) {
          launch(args);
      }
  
  }
  </code></pre>
  
  <p>The handler for the login button is located in another class (controller class made by the NetBeans IDE). I can't figure out what the frame's name is in order to use it in the controller class.</p>
  
  <p>Any help will be much appreciated!</p>
