[FIXED] How to hide "stage1" after you show "stage2" on a button click [JavaFX]

Issue

I have 2 .fxml files (stage1.fxml and stage2.fxml) and its controller class.

I have a button in stage1.fxml which opens stage2.fxml when clicked, it has this code on it:

public void btnStage2(ActionEvent event) {
        try {
            Parent stage2 = FXMLLoader.load(getClass().getResource("/application/stage2.fxml"));
            Stage stage = new Stage();
            stage.setScene(new Scene(stage2));
            stage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }

this opens stage2 just fine, however the stage1 is still open and I can just tab into it and still use the buttons in that stage, and I don't want that.

How can I .setVisible(false) the stage1 when I press the btnStage2 just before opening the stage2.fxml?

I found other posts regarding "hiding" the stage instead of closing it when I pressed the close button, but that doesn't match my need. Thanks for the help!

Solution

after hours of trial and error, I think I finally understood how stage.close() works.

the solution to my problem is to just slap these 2 lines of code in the method for the button:

Stage stage1= (Stage) btnStage2.getScene().getWindow();
stage1.close();

Previously, I thought that I cannot call multiple Stage in a single function. Turns out I was wrong.
