Show other window when click button JavaFX

Question

I want to solve my homework and I don't know how to start; the goal is to make 2 GUI Forms in JavaFX. The 1st is home form that contains Button1, and when the user clicks Button1 : show the 2nd Form and close the 1st.

How to do that ? hope to give me examples.

Thanks for reading and helping.

You can do something like this, but please keep in mind that we learn via practicing and training, try to do your own one after having a look at the idea in this example:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class TwoForms extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        StackPane root = new StackPane(); // TLC (Top Layer Container) a root container for all other components, which in your case is the Button 
        Button button = new Button("Go To Second Form"); // the button
        root.getChildren().add(button); // add the button to the root
        Scene scene = new Scene(root, 500,500); // create the scene and set the root, width and height
        primaryStage.setScene(scene); // set the scene
        primaryStage.setTitle("First Form");
        primaryStage.show();

        // add action listener, I will use the lambda style (which is data and code at the same time, read more about it in Oracle documentation)
        button.setOnAction(e->{
            //primaryStage.close(); // you can close the first stage from the beginning

            // create the structure again for the second GUI
            // Note that you CAN use the previous root and scene and just create a new Stage 
            //(of course you need to remove the button first from the root like this, root.getChildren().remove(0); at index 0)
            StackPane root2 = new StackPane();
            Label label = new Label("Your are now in the second form");
            root2.getChildren().add(label);
            Scene secondScene = new Scene(root2, 500,500);
            Stage secondStage = new Stage();
            secondStage.setScene(secondScene); // set the scene
            secondStage.setTitle("Second Form");
            secondStage.show();
            primaryStage.close(); // close the first stage (Window)
        });
    }

    public static void main(String[] args) {
        launch();

    }

}

Result

After Clicking on the Button -> Second Window.
