У меня есть приложение Java, содержащее одно текстовое поле, и я использую джойстик.

Как я могу что-то сделать в текстовом поле при нажатии кнопки джойстика?

На основе учебника проекта здесь: https://theuzo007.wordpress.com/2013/10/26/joystick-in-java-with-jinput-v2/ это выглядит, как вы должны цикла и просто проверить вещи, так

private void con(){ 
    JInputJoystick joystick = new JInputJoystick(Controller.Type.STICK); 
    while (joystick.isControllerConnected()) { 
     // Go trough all components of the controller. 
     Component[] components = joystick.getComponents(); 
     for(int i=0; i < components.length; i++) { 
      Component component = components[i]; 
      Identifier componentIdentifier = component.getIdentifier(); 

      // Buttons 
      if(componentIdentifier.getName().matches("^[0-9]*$")){ // If the component identifier name contains only numbers, then this is a button. 
       // Is button pressed? 
       if(component.getPollData() != 0.0f) { 
        txt.setText("Button got pressed!") 
       } 
      } 
     } 

     // We have to give processor some rest. 
     try { 
      Thread.sleep(25); 
     } catch (InterruptedException ex) { 
      Logger.getLogger(JoystickTest.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    } 
    txt.setText("Controller not connected"); 
}
