About Java-FX Controller

public class SettingsController implements  Initializable{
 @Override
  public void initialize(URL location, ResourceBundle resources) {
   
}
}

This is the way to write controller class in javafx

But  remember some point about controller class in javafx

- It is not necessary to extends Initialization interface to create controller class
- But if you implements initialization interface then it is necessary to override initialize method as shown

second way :

public class SettingsController {

  public void initialize() {
   
}
}

this is also a correct way to create controller class in jaavfx


Note - method name should be initialize it is starting point of your controller class

ex : public class SettingController
{
init(){
This is not a valid controller class
}
}
