my question how to load register form in main.java and on click signup button i need to switch registerform

i set controller,onaction,fx:id to login.fxml

Share your fxml file and what do you mean by switching? Hide the signup anchorpane and show registerform??? Or keep both visible? — IR Emon
i designed two fxml file one is for login form and other register form...if i clicked signup button which is in login form stage(window) it should open register form window — Anish Kumar Ramagiri
So actually you want to load a different fxml file in the same scene, right? Currently you are calling same method showSignUp() in the button action which loads the same fxml in the scene. So if you are trying what i said, first load the login fxml and load the register form in button action — IR Emon
first its loading login form.. how to load register form in main.java. can u help me in this... actually i didnt defined code for showSignUp method in main.java. — Anish Kumar Ramagiri
Do you want to load the register form in the same window, or in a new window? — IR Emon

You should have an AnchorPane in login.fxml which will be the parent and will be the container of all other elements and i set anchorPane as the id of that Anchorpane (you can choose yours). After doing it, you just need to add these code section in your controller class

@FXML AnchorPane anchorPane;

@FXML
private void RegisterStage() throws IOException {
    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("reg.fxml"));
    Pane registerPane = (Pane) fxmlLoader.load();
    try {
        anchorPane.getChildren().clear();
        anchorPane.getChildren().add(registerPane);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Replace the reg.fxml by your desired fxml you want to load.
