You need something like this in HomeScreenController

Use this in your Button (ActionListener): // YOU CAN USE ANONYMOUS INNER ...

public void ActionPerformed(ActionEvent e){
    if(e.getSource() == but){
        HomeScreenController h = new HomeScreenController(this); 

Use this in your HomeScreenController Class

public class HomeScreenController{
    public LoginScreenController main;
    public HomeScreenController(LoginScreenController login){
        this.main = login;

you can use variable main to change data from your LoginScreenController

Declare this in your LoginScreenController:
Public String data= "";
Usage in HomeScreenController:
main.data = field.getText();

 i have written code like this in button Ok click event getting incompatible type error

 @FXML public void handleOk( final ActionEvent e){

        btnOk.setOnAction(new EventHandler<ActionEvent>(){

            public void handle(ActionEvent t) {
              if(e.getSource() == btnOk){
                    HomeScreenController rpt = new HomeScreenController(this); /* incompatible types: <anonymous EventHandler<ActionEvent>> cannot be converted to LoginScreenController*/



        main.data = txtData.getText();

Is your class "LoginScreenController" extended to JFrame or JPanel?
Maybe that helps? or try this:

(Sorry I don't have time to write some test programs to check for myself)
